Authors: Martínez H. Salvador
Published: November 2020

Resumen: Estudio sobre el origen del humanismo vernáculo castellano en el ámbito del humanismo medieval. Se analizan sus características, contrastándolas con las del humanismo latino clasicista del siglo XV. Se ilustra por qué es un humanismo total, que, por influjo de la filosofía aristotélica, incluye las letras y las ciencias, e integrador de las tres culturas presentes en la sociedad peninsular del siglo XIII, las cuales usaron el vernáculo como lengua común.Palabras clave: Humanismo medieval, humanismo vernáculo, humanismo latino clasicista, el castellano lengua de cultura, Alfonso X el Sabio.Abstract: A study of the origins of Castilian vernacular humanism in the context of medieval humanism. Its characteristics are analyzed and contrasted with the Latin classicist humanism of the XVth Century. The study illustrates why vernacular humanism, due to the influence of the Aristotelian philosophy, is comprehensive, integrating both the letters and the sciences, and it is inclusive of all three cultures present in the Spanish society of the XIIIth Century that used the vernacular as their common language.Keywords: Medieval humanism, vernacular humanism, Latin classicist humanism, Castilian as language of culture, Alfonso X the Learned.

In this study, the possibility of the formation of lower olefins from dimethyl ether and methanol on catalysts containing Mg-Zn-Zr-B-HSZ and Mg-Zn-Zr-P-HSZ was studied, and the process was evaluated quantum chemically. According to the results obtained by IR-Fur spectroscopy, during the catalytic conversion of DME (dimethyl ether) on the surface of catalysts containing Mg-Zn-Zr-B-HSZ and Mg-Zn-Zr-P-HSZ ketenes at temperatures below 180 °C and oxonium intermediates at 320 °C (intermediate). compounds) are confirmed by experimental spectra and theoretical quantum-chemical calculations. It was shown that the formation of olefins below DME occurs by the carbene mechanism at low temperatures and by the oxonylide mechanism at high temperatures.

The effect of intrinsic image memorability on recollection and familiarity
Authors: Broers N. , Busch N.A.
Published: November 2020

Many photographs of real-life scenes are very consistently remembered or forgotten by most people, making these images intrinsically memorable or forgettable. Although machine vision algorithms can predict a given image’s memorability very well, nothing is known about the subjective quality of these memories: are memorable images recognized based on strong feelings of familiarity or on recollection of episodic details? We tested people’s recognition memory for memorable and forgettable scenes selected from image memorability databases, which contain memorability scores for each image, based on large-scale recognition memory experiments. Specifically, we tested the effect of intrinsic memorability on recollection and familiarity using cognitive computational models based on receiver operating characteristics (ROCs; Experiment 1 and 2) and on remember/know (R/K) judgments (Experiment 2). The ROC data of Experiment 2 indicated that image memorability boosted memory strength, but did not find a specific effect on recollection or familiarity. By contrast, ROC data from Experiment 2, which was designed to facilitate encoding and, in turn, recollection, found evidence for a specific effect of image memorability on recollection. Moreover, R/K judgments showed that, on average, memorability boosts recollection rather than familiarity. However, we also found a large degree of variability in these judgments across individual images: some images actually achieved high recognition rates by exclusively boosting familiarity rather than recollection. Together, these results show that current machine vision algorithms that can predict an image’s intrinsic memorability in terms of hit rates fall short of describing the subjective quality of human memories.

O ouro sai à rua: a presença de ornatos áureos nas festividades populares do século XX e alvores do século XXI
Authors: Mota Rosa Maria
Published: November 2020

Este artigo pondera sobre a ligação entre a utilização de adornos de ouro inicialmente utilizados no quotidiano das povoações rurais, e as romarias e festas populares. Para tal, salientamos a sua ligação aos trajes regionais, às vestes rituais e à religião católica, aqui por meio dos ex-votos em ouro e da ornamentação das imagens sacras, dos figurantes nas procissões e dos andores que as compõem. Escolhemos acontecimentos situados em zonas diferenciadas como o Minho, a Beira Baixa e o Alentejo, com diferentes tradições no uso de ornamentos áureos — que encontra no Norte de Portugal a sua maior expressão —, mostrando que este facto ocorre em todo o território nacional
Paisagens de Macau (sécs. XVIII-XIX). “Vue de Macao en Chine” versus” On the Green”
Authors: Guimarães Martins da Costa Maria Alexandrina
Published: November 2020

O Museu do Centro Científico e Cultural de Macau (CCCM) conserva no seu acervo uma gravura e um desenho com vistas da cidade de Macau, dos finais do séc. XVIII e da primeira metade do séc. XIX. A primeira, “Vue de Macao en Chine”, data de 1787 e é da autoria de Gaspard Duché de Vancy e o segundo, “On the Green”, um pouco mais tardio, é do ano de 1838 e foi desenhado por Warner Varnham.

Estes dois exemplares oferecem-nos perspectivas complementares e extremamente interessantes da cidade de Macau. Nos mesmos é possível reconhecer paisagens físicas e humanas e reconstituir ambientes.

Estas imagens serão analisadas em paralelo, nas suas semelhanças e diferenças e, no âmbito deste estudo, serão cruzadas com memórias escritas coevas, de forma a atingir-se outros níveis de compreensão e de leitura da realidade da época, para além da dimensão estritamente visual que as mesmas encerram.
Francisco de Holanda ou o simulacro do génio
Authors: Medeiros Vasco
Published: November 2020

A dimensão universal de Francisco de Holanda constitui facto incontestável. Face ao axioma, urge libertar a visão de constrangimentos e miopias na análise do homem real, distante da mitificação histórica e teórica formulada nas multiplas páginas que a sua proficua tratadística originou. Holanda vincula-se conscientemente ao papel do génio maneirista, cujo desprendimento teórico não constitui óbice à formulação artística, antes pelo contrário. No entanto, este posicionamento dificilmente se enquadra com a estrutura teórica dos multiplos tratados e manifestos que compôs. A Idea, imagem pura e liberta de quaisquer constrangimentos assumirá papel preponderante no ideário maneirista, constituindo o seu abnegado anticlassicismo, verdadeiro libelo contestatário contra a crescente cientificação da arte. Do seu confronto com este universo dissonante — de génio multisciente à singularidade de génio criador — Holanda irá conjugar em si duas paradoxais dimensões: Um simulacro de erudição em clara oposição à Terribilitá deformante e irreverente do espírito maneirista.

Architecture, Ceramics and Frames. Three case studies in the work of Jorge Barradas
Authors: Almeida Ana
Published: November 2020

Throughout the history of the azulejo (a Portuguese form of tin-glazed ceramic tile), frames have played a decisive role in the articulation of this element with its architectural support. From the late 1940s onwards, Portuguese artists have felt the influence of the International Modern Movement, especially via the Brazilian model and its solutions for integrating azulejos within the new architectural forms. This movement translated into new buildings and equipments, promoting the interaction between architects and artists. Moreover, it led to the renovation of Portuguese ceramic coverings, prompted by the emergence of a new generation of artists strongly influenced by Jorge Barradas.

The present article aims to examine three ceramic coverings by Jorge Barradas, focusing on their frames and their articulation with the architecture. The first azulejo covering is the so-called Atlântico Palace, the headquarters of a banking institution in Oporto (1950); the second is located at the Parish Church of Nossa Senhora de Fátima, in Parede, Cascais (1953); the third one is at the Lisbon’s Palace of Justice (1969).
Os bens do extinto Convento de S. João de Deus em Lisboa
Authors: Montezuma de Carvalho Carmina , Pereira das Neves Rodrigues Estela Maria
Published: November 2020

O Convento de S. João de Deus, em Lisboa, foi fundado, em 1629, pela Ordem Hospitaleira de S. João de Deus; ao longo de 200 anos, garantiu a assistência na saúde a religiosos, militares e civis. Com a extinção do Convento, em 1834, grande parte dos seus bens foram incorporados na Fazenda Nacional. Desconhece-se o seu atual paradeiro, à exceção de alguns núcleos que serão analisados neste artigo. A preservação e divulgação da memória histórica sobre a assistência médico-hospitalar dos Irmãos Hospitaleiros está consignada no Museu S. João de Deus – Psiquiatria e História, inaugurado em 2009; a investigação arquivística referente aos inventários dos bens móveis que as autoras têm vindo a efetuar é, por este motivo, fundamental para complemento da divulgação junto do público.
De Hospital da Misericórdia a Museu de Arte Sacra da Ilha de Moçambique (séc. XVI-1969)
Authors: Mariz Vera
Published: November 2020

Como testemunhos eloquentes dos primeiros tempos da ocupação portuguesa na primeira capital da colónia, a igreja da Misericórdia e o respectivo hospital da Ilha de Moçambique, sobreviveram, ao longo dos séculos, a várias tormentas, caso da extinção das Ordens Religiosas ou da separação do Estado e das Igrejas. Ainda assim, ao longo de uma vida marcada por momentos de prestígio e outros de decadência, o núcleo da Santa Casa da Misericórdia da ilha de Moçambique reuniu um tesouro considerável que, durante o Estado Novo, originou o Museu de Arte Sacra.

Authors: Amado Maria Tereza
Published: November 2020

Este artigo apresenta uma proposta de revalorização do Mosteiro beneditino de Santa Maria de Pombeiro, fundado no seculo XI, perto de Felgueiras e próximo de Tibães. A partir de uma reflexão sobre o atual valor da realidade patrimonial, e sobre o significado que tem hoje para nós a sua dinamização, explicitam-se as razões da singularidade desta comunidade. Razões que se prendem com a história e o passado de Pombeiro, mas que estão também relacionadas com a especificidade do seu presente, e que facilitam e impõem a sua musealização. Analisa-se ainda a relevância do uso das novas tecnologias neste projeto sociocultural.

O Património Histórico-artístico das Ordens Religiosas no debate sobre a Reforma dos Regulares entre 1789 e 1830
Authors: Costa Lima Madalena
Published: November 2020

Os trabalhos para um nunca executado e polémico plano de reforma das ordens regulares estiveram na origem de múltiplas avaliações ao património eclesial do reino, previamente à implementação plena do Liberalismo em Portugal. As diligências foram oficializadas em 1789 e prosseguiram intermitentemente até 1830, centrando-se na supressão de um largo número de casas regulares. Iremos analisar as observações feitas, no âmbito deste processo, ao património histórico e artístico das ordens. Destacaremos o modo como ele antecipou e em certa medida contribuiu para os sucessos decorrentes da extinção definitiva dos regulares durante os primeiros anos do Portugal Liberal.
Coleccionismo e integração de património monástico em Portugal no início do século XX. A colecção José Relvas
Authors: Artur Grilo Fernando Jorge
Published: November 2020

O presente estudo pretende discutir, com base em documentação inédita do arquivo pessoal de José de Mascarenhas Relvas (1858-1929), o modo como o colecionador integrou na sua colecção de obras de arte um conjunto de peças provenientes do património monástico português e que integram a exposição permanente da Casa dos Patudos – Museu de Alpiarça. Como o fez, com que intuito e, principalmente, com que paixão as estudou e integrou na sua vivência quotidiana, são algumas das questões que desejo estudar, recorrendo às informações que o seu inesgotável arquivo pessoal vai revelando e a um conhecimento cada vez mais alargado da coleção.
O conjunto pictórico oriundo da capela-mor da igreja do Convento das Trinas do Mocambo: subsídios para o seu estudo
Authors: Desterro Maria Teresa
Published: November 2020

O presente estudo tem como objectivo essencial lançar um novo olhar sobre as quase ignotas pinturas que actualmente decoram os altares laterais da igreja de S. Francisco de Tomar, oriundas da capela-mor da igreja do extinto Convento de Nossa Senhora da Soledade das Trinas do Mocambo, de Lisboa. Dedicadas a temas marianos, a nossa proposta de datação situa a sua feitura no segundo quartel do século XVIII (c.1730-40) e cremo-las tributáveis a um dos sequazes do fa presto Bento Coelho da Silveira. A análise pictórica das mesmas revela, contudo, um pintor mais evoluído compositivamente, já liberto do penumbrismo seiscentista e aberto às novas influências ítalo-francesas, nomeadamente de Simon Vouet, Chaperon e Maratti.

Tempos de mudança, tempos de perda: o Património conventual português no século XIX. Testemunhos de vandalismo
Authors: Massano Rodrigues Rute
Published: November 2020

A conjuntura política, social e financeira de Portugal durante o século XIX levou a que, de diversas formas, o património conventual fosse alvo de atos que contribuíram para a sua ruína. A falta de rendimentos, as invasões francesas, a guerra civil, a Reforma Geral Eclesiástica, a extinção das ordens religiosas (1834) e a desamortização dos seus bens, o encerramento dos conventos femininos, a complexa gestão estatal, constituíram, entre outras, condições favoráveis ao desenvolvimento de atitudes que se enquadram no âmbito daquilo que, habitualmente, designamos de vandalismo. Monumentos tão importantes como os mosteiros de Alcobaça ou Santa Maria de Belém não escapariam à indiferença, incúria, destruição, descontextualização. Os registos deixados por alguns intelectuais oitocentistas, e por fontes documentais como as apresentadas, algumas inéditas, mostram-se imprescindíveis para a compreensão das várias vertentes do vandalismo nos conventos e seus espólios, núcleos importantes do património arquitetónico e artístico nacional.
Contributos para uma ideia de destruição na Cultura Artística Contemporânea
Authors: Rosa Grincho Serra Rui Alexandre
Published: November 2020

Que situações históricas, que pensamentos, que atitudes, que enquadramentos, estarão na génese de uma dimensão negativa, pessimista e redutora da arte contemporânea e actual? Poderão ser múltiplas as respostas. Tentaremos apresentá-las em duas principais vertentes de actuação: definindo o pensamento filosófico do século XIX, que contribuiu para a ideia de derrocada progressiva dos valores ocidentais, com as contribuições da “morte da arte” de Hegel e o niilismo no pensamento de Nietzsche; e demonstrando um mal-estar existencial no século XX, com as vanguardas modernistas, subsidiárias das duas guerras mundiais e do holocausto nazi, com as noções de desumanização e decadência do mundo ocidental, com o situacionismo e a Guerra Fria, e, na actualidade, com a pós-modernidade e a realidade reduzida a pressupostos mediáticos.

A análise da composição considera a conjuntura sociopolítica de então, cruzando-a com as opções iconográficas tomadas pelo artista e com a integração no espaço arquitectónico para o qual o painel foi concebido. É objetivo deste artigo contribuir para uma reflexão acerca da apropriação das artes plásticas pelo poder político para veiculação de mensagens ideológicas, concretamente no período do Estado Novo.
O Sistema da Arte Contemporânea é Livre?
Authors: F. R. Costa Júlio
Published: November 2020

A presente reflexão aborda a liberdade artística no âmbito do mundo da arte contemporânea– desenvolvido a partir do conceito de Artworld de Arthur C. Danto. Desta forma, pensa-se a ligação do artista e da sua obra à sociedade, e das restrições e liberdades que advêm desta relação dialéctica. Tendo como base que: a liberdade do artista é definida pelas condições de possibilidade de concretizar a sua obra; sendo que este intervalo de possibilidade vai desde o momento em que a obra é apenas uma “semente” no pensamento até o momento em que é exposta – a partir deste ponto a obra segue também uma vida própria.

Em última instância, procura-se abrir caminho ao debate em torno das relações de poder dentro das hie­rarquias que formam o mundo da arte, realçando as consequências principais para a cultura ao nível da sociedade ocidental.

The link between Portuguese tile decorations and the notion of identity(ies) is rooted today in a very wide context, leading to the extensive use of azulejos as cultural and narrative symbols with very different aims. The purpose of the present article is go back in time, to the mid 19th century, and to debate the role played by European historiography in the emergence of the azulejo as an “identitarian” art form, considering its unique characteristics and the main moments and agents that have contributed to the creation and consolidation of this phenomenon.
A Homeland divided in Squares: Joaquim de Vasconcelos (1849-1936) Identity Panels
Authors: Leandro Sandra
Published: November 2020

Considered the founder of Art History in Portugal with a rigorous method, Joaquim de Vasconcelos was also a Musicologist, Museologist, Teacher and Professor, Art Critic and a “champion” of visual transmission “systems” like Photography and Drawing. His capacity for critical analysis, his anarchic enthusiasm for various areas of knowledge, providing ways of thinking and acting when almost everything was still undone, impose him as an anti-mythical and unique character who created his own legend, a myth and a romantic hero, a master of himself far beyond from Gottfried Semper (1803-1879) or Giambattista Cavalcaselle (1819-1897) just to point out two of the masters that he admired. Homeland squares are not only a way of referring how tiles are a very important part of the Portuguese identity puzzle, but also a way of alluding to the geometry of parallels and meridians that Joaquim de Vasconcelos drew when trying to identify the Art in Portugal.
The Azulejo as Colonial Symbol of Power: a Deconstruction through Sugar and Art
Authors: Miller Shelley
Published: November 2020

I create murals that look like azulejos, depicting caravels and many decorative features seen in traditional azulejos, but my murals are made entirely of sugar. I make the sugar tiles and hand paint them with edible inks.

I am interested in the azulejo, specifically with imagery of ships, as a symbol of colonial power and of national pride (the Nation of Portugal), but only for the means to subvert this pride. I developed this work in Brazil, addressing the country’s history of colonization and the slave trade that supported Portugal’s sugar empire.

I continue to use the blue tile reference, even outside the context of Brazil, because I want to reference the general construct of colonization and slavery, showing how oppression has found new forms. I install my ephemeral murals on city walls, where they wash away, fade, crumble and decay, animating a more realistic version of history.
Arte e Iconografia da Vida e da Morte
Authors: Rodarte Veloso Carlos
Published: November 2020

As artes fi gurativas exigem dos seus estudiosos a observação e identifi cação dos temas representados através de duas disciplinas auxiliares, a Iconografi a e a Iconologia, muitas vezes confundidas uma com a outra. Foi Erwin Panofsky o grande historiador da Arte, que distinguiu estes conceitos em “Estudos de Iconologia”, em 1939. A “Última Ceia” de Leonardo da Vinci, revela uma interpretação muito renascentista das atitudes dos apóstolos, que manifestam magistralmente a dúvida que corrói a assembleia quando Cristo anuncia a traição de um dos seus. Esta duplicidade de atitudes invade todas as épocas artísticas, quando os mesmos elementos gráficos podem ser interpretados de formas diametralmente opostas, caso do “carpe diem” greco-romano que se converte nas “danças macabras” da Idade Média, associadas à condenação da “Vanitas”. Sempre e sempre, a lembrança da morte inevitável, a influenciar os comportamentos humanos, tanto pela busca do prazer enquanto é tempo, como pela preparação de uma boa e virtuosa morte, recompensada num problemático Além.
Entre Sobrevivências e Deslocamentos: a imagem e o fantasma em Aby Warburg
Authors: Carvalho Nunes Mateus
Published: November 2020

Investigam-se, neste trabalho, as contribuições do historiador da arte, da cultura e teórico da imagem alemão Aby Warburg (1866-1929), entendendo a obra warburguiana como uma autobiografia, a partir da perspetiva do conceito de “biografema” do fi lósofo francês Roland Barthes (1915-1980). Pretende-se discutir as contribuições de Warburg para o campo da História da Arte a partir da análise das imagens e de seus deslocamentos sintomáticos no campo da representação simbólica, principalmente sobre o conceito de sobrevivência. Investigam-se as operações imagéticas e historiográficas transdisciplinares e trans-históricas de Aby Warburg, abordando a complexidade dos objetos artísticos e de suas temporalidades, além de suas potencialidades para novas metodologias na História da Arte.

Architectures of Exoplanetary Systems. III. Eccentricity and Mutual Inclination Distributions of AMD-stable Planetary Systems
Authors: He Matthias Y. , Ford Eric B. , Ragozzine Darin , Carrera Daniel
Published: November 2020

The angular momentum deficit (AMD) of a planetary system is a measure of its orbital excitation and a predictor of long-term stability. We adopt the AMD-stability criterion to constrain the orbital architectures for exoplanetary systems. Previously, He et al. showed through forward modeling (SysSim) that the observed multiplicity distribution can be well reproduced by two populations consisting of a low and a high mutual inclination component. Here, we show that a broad distribution of mutual inclinations arising from systems at the AMD-stability limit can also match the observed Kepler population. We show that distributing a planetary system’s maximum AMD among its planets results in a multiplicity-dependent distribution of eccentricities and mutual inclinations. Systems with intrinsically more planets have lower median eccentricities and mutual inclinations, and this trend is well described by power-law functions of the intrinsic planet multiplicity (n):and, whereandare the medians of the eccentricity and inclination distributions. We also find that intrinsic single planets have higher eccentricities (σe,1 ∼ 0.25) than multiplanet systems and that the trends with multiplicity appear in the observed distributions of period-normalized transit duration ratios. We show that the observed preferences for planet-size orderings and uniform spacings are more extreme than what can be produced by the detection biases of the Kepler mission alone. Finally, we find that for systems with detected transiting planets between 5 and 10 days, there is another planet with a greater radial velocity signal ≃53% of the time.

We present an optical-to-infrared transmission spectrum of the inflated sub-Saturn KELT-11b measured with the Transiting Exoplanet Survey Satellite (TESS), the Hubble Space Telescope (HST) Wide Field Camera 3 G141 spectroscopic grism, and the Spitzer Space Telescope (Spitzer) at 3.6 μm, in addition to a Spitzer 4.5 μm secondary eclipse. The precise HST transmission spectrum notably reveals a low-amplitude water feature with an unusual shape. Based on free-retrieval analyses with varying molecular abundances, we find strong evidence for water absorption. Depending on model assumptions, we also find tentative evidence for other absorbers (HCN, TiO, and AlO). The retrieved water abundance is generally ≲0.1× solar (0.001–0.7× solar over a range of model assumptions), several orders of magnitude lower than expected from planet formation models based on the solar system metallicity trend. We also consider chemical-equilibrium and self-consistent 1D radiative-convective equilibrium model fits and find that they, too, prefer low metallicities ([M/H] ≲ −2, consistent with the free-retrieval results). However, all of the retrievals should be interpreted with some caution because they either require additional absorbers that are far out of chemical equilibrium to explain the shape of the spectrum or are simply poor fits to the data. Finally, we find that the Spitzer secondary eclipse is indicative of full heat redistribution from KELT-11b’s dayside to nightside, assuming a clear dayside. These potentially unusual results for KELT-11b’s composition are suggestive of new challenges on the horizon for atmosphere and formation models in the face of increasingly precise measurements of exoplanet spectra.
Endogenic and Exogenic Contributions to Visible-wavelength Spectra of Europa’s Trailing Hemisphere

Published: November 2020

The composition of Europa’s trailing hemisphere reflects the combined influences of endogenous geologic resurfacing and exogenous sulfur radiolysis. Using spatially resolved visible-wavelength spectra of Europa obtained with the Hubble Space Telescope, we map multiple spectral features across the trailing hemisphere and compare their geographies with the distributions of large-scale geology, magnetospheric bombardment, and surface color. Based on such comparisons, we interpret some aspects of our spectra as indicative of purely exogenous sulfur radiolysis products and other aspects as indicative of radiolysis products formed from a mixture of endogenous material and magnetospheric sulfur. The spatial distributions of two of the absorptions seen in our spectra—a widespread downturn toward the near-UV and a distinct feature at 530 nm—appear consistent with sulfur allotropes previously suggested from ground-based spectrophotometry. However, the geographies of two additional features—an absorption feature at 360 nm and the spectral slope at red wavelengths—are more consistent with endogenous material that has been altered by sulfur radiolysis. We suggest irradiated sulfate salts as potential candidates for this material, but we are unable to identify particular species with the available data.

High-contrast imaging of exoplanets and protoplanetary disks depends on wave front sensing and correction made by adaptive optics instruments. Classically, wave front sensing has been conducted at optical wavelengths, which made high-contrast imaging of red targets such as M-type stars or extincted T Tauri stars challenging. Keck/NIRC2 has combined near-infrared (NIR) detector technology with the pyramid wave front sensor (PWFS). With this new module we observed SR 21, a young star that is brighter at NIR wavelengths than at optical wavelengths. Compared with the archival data of SR 21 taken with the optical wave front sensing we achieved ∼20% better Strehl ratio in similar natural seeing conditions. Further post-processing utilizing angular differential imaging and reference-star differential imaging confirmed the spiral feature reported by the Very Large Telescope/Spectro-Polarimetric High-contrast Exoplanet REsearch instrument polarimetric observation, which is the first detection of the SR 21 spiral in total intensity at L′ band. We also compared the contrast limit of our result (10−4 at 04 and 2 × 10−5 at 10) with the archival data that were taken with optical wave front sensing and confirmed the improvement, particularly at ≤05. Our observation demonstrates that the NIR PWFS improves AO performance and will provide more opportunities for red targets in the future.

Radio campaigns using maser stellar beacons have provided crucial information to characterize Galactic stellar populations. Currently, the Bulge Asymmetries and Dynamical Evolution (BAaDE) project is surveying infrared (IR) color-selected targets for SiO masers. This provides a sample of evolved stars that can be used to study the inner, optically obscured Galaxy using line-of-sight velocities and possibly very long baseline interferometry proper motions. In order to use the BAaDE sample for kinematic studies, the stellar population should be characterized. In this study, the BAaDE targets have been cross-matched with IR (2MASS) and optical (Gaia) samples. By exploring the synergies of this cross-match together with Gaia parallaxes and extinction maps, the local (d < 2 kpc) asymptotic giant branch (AGB) stars can be characterized. We have defined a BAaDE–Gaia sample of 20,111 sources resulting from cross-matching BAaDE targets with IR and optical surveys. From this sample, a local sample of 1812 evolved stars with accurate parallax measurements, confirmed evolved stellar evolution stage, and within 2 kpc distance around the Sun was selected, for which absolute (bolometric) magnitudes are estimated. The evolved stellar population with Gaia counterparts that are variable seems to be predominantly associated with AGB stars with moderate luminosity (

) and periods between 250 and 1250 days.

Observational studies are increasingly finding evidence against major mergers being the dominant mechanism responsible for triggering an active galactic nucleus (AGN). After studying the connection between major mergers and AGNs with the highest Eddington ratios at z = 2, we here expand our analysis to

, exploring the same AGN parameter space. Using ESO VLT/FORS2

,

, and color images, we examine the morphologies of 17 galaxies hosting AGNs with Eddington ratios

, and 25 mass- and redshift-matched control galaxies. To match the appearance of the two samples, we add synthetic point sources to the inactive comparison galaxies. The combined sample of AGN and inactive galaxies was independently ranked by 19 experts with respect to the degree of morphological distortion. We combine the resulting individual rankings into multiple overall rankings, from which we derive the respective major merger fractions of the two samples. With a best estimate of f
m,agn = 0.41 ± 0.12 for the AGN host galaxies and f
m,ina = 0.08 ± 0.06 for the inactive galaxies, our results imply that our AGN host galaxies have a significantly higher merger rate, regardless of the observed wavelength or applied methodology. We conclude that although major mergers are an essential mechanism to trigger local high Eddington ratio AGNs at

of this specific AGN subpopulation still remains unclear.

We present observations toward HOPS 383, the first known outbursting Class 0 protostar located within the Orion molecular cloud using the Atacama Large Millimeter/submillimeter Array (ALMA), Very Large Array (VLA), and Submillimeter Array (SMA). The SMA observations reveal envelope scale continuum and molecular line emission surrounding HOPS 383 at 0.85, 1.1, and 1.3 mm. The images show that HCO+ and H13CO+ peaks on or near the continuum, while N2H+ is reduced at the same position. This reflects the underlying chemistry where CO evaporating close to the protostar destroys N2H+ while forming HCO+. We also observe the molecular outflow traced by 12CO (

) and (

). A disk is resolved in the ALMA 0.87 mm dust continuum, orthogonal to the outflow direction, with an apparent radius of ∼62 au. Radiative transfer modeling of the continuum gives disk masses of 0.02 M
⊙ when fit to the ALMA visibilities. The models including VLA 8 mm data indicate that the disk mass could be up to a factor of 10 larger due to lower dust opacity at longer wavelengths. The disk temperature and surface density profiles from the modeling, and an assumed protostar mass of 0.5 M
⊙ suggest that the Toomre Q parameter < 1 before the outburst, making gravitational instability a viable mechanism to explain outbursts at an early age if the disk is sufficiently massive.
A Photoionized Accretion Disk around a Young High-mass Star

Published: November 2020

We present high spatial resolution (52 au) observations of the high-mass young stellar object (HMYSO) G345.4938+01.4677 made using the Atacama Large Millimeter/submillimeter Array. This O-type HMYSO is located at 2.38 kpc and is associated with a luminosity of 1.5 × 105
L
☉. We detect circumstellar emission from the H38β hydrogen recombination line showing a compact structure rotating perpendicularly to the previously detected radio jet. We interpret this emission as tracing a photoionized accretion disk around the HMYSO. While this disk-like structure seems currently too small to sustain continued accretion, the data present direct observational evidence of how disks can effectively survive the photoionization feedback from young high-mass stars. We also report the detection of a low-mass young stellar object in the vicinity of the HMYSO and suggest that it forms a high-mass and low-mass star binary system.
