Abstract
We combine the latest data sets obtained with different surveys to study the frequency dependence of polarized emission coming from extragalactic radio sources (ERS). We consider data over a very wide frequency range starting from 1.4 GHz up to 217 GHz. This range is particularly interesting since it overlaps the frequencies of the current and forthcoming cosmic microwave background (CMB) experiments. Current data suggest that at high radio frequencies (ν ≥ 20 GHz) the fractional polarization of ERS does not depend on the total flux density. Conversely, recent data sets indicate a moderate increase of polarization fraction as a function of frequency, physically motivated by the fact that Faraday depolarization is expected to be less relevant at high radio frequencies. We compute ERS number counts using updated models based on recent data, and we forecast the contribution of unresolved ERS in CMB polarization spectra. Given the expected sensitivities and the observational patch sizes of forthcoming CMB experiments, about ∼200 (up to ∼2000) polarized ERS are expected to be detected. Finally, we assess that polarized ERS can contaminate the cosmological B-mode polarization if the tensor-to-scalar ratio is <0.05 and they have to be robustly controlled to de-lens CMB B-modes at the arcminute angular scales.
Constraints on Short, Hard Gamma-Ray Burst Beaming Angles from Gravitational Wave Observations

Published: May 2018

Abstract
The first detection of a binary neutron star merger, GW170817, and an associated short gamma-ray burst confirmed that neutron star mergers are responsible for at least some of these bursts. The prompt gamma-ray emission from these events is thought to be highly relativistically beamed. We present a method for inferring limits on the extent of this beaming by comparing the number of short gamma-ray bursts (SGRBs) observed electromagnetically with the number of neutron star binary mergers detected in gravitational waves. We demonstrate that an observing run comparable to the expected Advanced LIGO (aLIGO) 2016–2017 run would be capable of placing limits on the beaming angle of approximately

, given one binary neutron star detection, under the assumption that all mergers produce a gamma-ray burst, and that SGRBs occur at an illustrative rate of

. We anticipate that after a year of observations with aLIGO at design sensitivity in 2020, these constraints will improve to

Abstract
We present 5–28 μm SOFIA FORECAST spectroscopy complemented by panchromatic X-ray through infrared observations of the CO nova V5668 Sgr documenting the formation and destruction of dust during ∼500 days following outburst. Dust condensation commenced by 82 days after outburst at a temperature of ∼1090 K. The condensation temperature indicates that the condensate was amorphous carbon. There was a gradual decrease of the grain size and dust mass during the recovery phase. Absolute parameter values given here are for an assumed distance of 1.2 kpc. We conclude that the maximum mass of dust produced was 1.2 × 10−7
M
⊙ if the dust was amorphous carbon. The average grain radius grew to a maximum of ∼2.9 μm at a temperature of ∼720 K around day 113 when the shell visual optical depth was τ
v ∼ 5.4. Maximum grain growth was followed by a period of grain destruction. X-rays were detected with Swift from day 95 to beyond day 500. The Swift X-ray count rate due to the hot white dwarf peaked around day 220, when its spectrum was that of a kT = 35 eV blackbody. The temperature, together with the supersoft X-ray turn-on and turn-off times, suggests a white dwarf mass of ∼1.1 M
⊙. We show that the X-ray fluence was sufficient to destroy the dust. Our data show that the post-dust event X-ray brightening is not due to dust destruction, which certainly occurred, as the dust is optically thin to X-rays.
Observing and Modeling the Gamma-Ray Emission from Pulsar/Pulsar Wind Nebula Complex PSR J0205+6449/3C 58

Abstract
We present the results of the analysis of eight years of Fermi-LAT data of the pulsar/pulsar wind nebula complex PSR J0205+6449/3C 58. Using a contemporaneous ephemeris, we carried out a detailed analysis of PSR J0205+6449 both during its off-peak and on-peak phase intervals. 3C 58 is significantly detected during the off-peak phase interval. We show that the spectral energy distribution at high energies is the same disregarding the phases considered, and thus that this part of the spectrum is most likely dominated by the nebula radiation. We present results of theoretical models of the nebula and the magnetospheric emission that confirm this interpretation. Possible high-energy flares from 3C 58 were searched for, but none were unambiguously identified.

Abstract
We present a catalog of 10,718 objects in the COSMOS field, observed through multi-slit spectroscopy with the Deep Imaging Multi-Object Spectrograph (DEIMOS) on the Keck II telescope in the wavelength range ∼5500–9800 Å. The catalog contains 6617 objects with high-quality spectra (two or more spectral features), and 1798 objects with a single spectroscopic feature confirmed by the photometric redshift. For 2024 typically faint objects, we could not obtain reliable redshifts. The objects have been selected from a variety of input catalogs based on multi-wavelength observations in the field, and thus have a diverse selection function, which enables the study of the diversity in the galaxy population. The magnitude distribution of our objects is peaked at I
AB ∼ 23 and K
AB ∼ 21, with a secondary peak at K
AB ∼ 24. We sample a broad redshift distribution in the range 0 < z < 6, with one peak at z ∼ 1, and another one around z ∼ 4. We have identified 13 redshift spikes at z > 0.65 with chance probabilities < 4 × 10−4, some of which are clearly related to protocluster structures of sizes >10 Mpc. An object-to-object comparison with a multitude of other spectroscopic samples in the same field shows that our DEIMOS sample is among the best in terms of fraction of spectroscopic failures and relative redshift accuracy. We have determined the fraction of spectroscopic blends to about 0.8% in our sample. This is likely a lower limit and at any rate well below the most pessimistic expectations. Interestingly, we find evidence for strong lensing of Lyα background emitters within the slits of 12 of our target galaxies, increasing their apparent density by about a factor of 4.
Around the Way: Testing ΛCDM with Milky Way Stellar Stream Constraints
Authors: Dai Biwei , Robertson Brant E. , Madau Piero 
Published: May 2018

Abstract
Recent analyses of the Pal 5 and GD-1 tidal streams suggest that the inner dark matter halo of the Milky Way is close to spherical, in tension with predictions from collisionless N-body simulations of cosmological structure formation. We use the Eris simulation to test whether the combination of dissipative physics and hierarchical structure formation can produce Milky Way–like galaxies whose dark matter halos match the tidal stream constraints from the GD-1 and Pal 5 clusters. We use a dynamical model of the simulated Eris galaxy to generate many realizations of the GD-1 and Pal 5 tidal streams, marginalize over observational uncertainties in the cluster galactocentric positions and velocities, and compare with the observational constraints. We find that the total density and potential of Eris contributed by baryons and dark matter satisfies constraints from the existing Milky Way stellar stream data, as the baryons both round and redistribute the dark matter during the dissipative formation of the galaxy, and provide a centrally concentrated mass distribution that rounds the inner potential. The Eris dark matter halo or a spherical Navarro–Frenk–White dark matter work comparably well in modeling the stream data. In contrast, the equivalent dark matter–only ErisDark simulation produces a prolate halo that cannot reproduce the observed stream data. The ongoing Gaia mission will provide decisive tests of the consistency between

and Milky Way streams, and should distinguish between models like Eris and more spherical halos.
Gender and the transsexual body in <i>Transamerica</i>
Authors: Jensen Amy A. 
Published: May 2018

Transamerica, by Duncan Tucker, released in 2005, addresses lesbian, gay, bisexual, transgender and queer- (LGBTQ-) related themes through a transsexual female protagonist, Bree. This article discusses the film as an important step in the direction of representing the complexity of gender, which, by today’s standards, is more generally appreciated. Because of its subject matter, Transamerica is a contentious film, lauded and condemned in mainstream media for how it dealt with and represented transsexual identities. Despite nominations for a number of awards, the film’s portrayal of transsexual identities was largely ignored in academic discourse at the time. I argue here that the film provides insight into the challenges, requirements, concerns, as well as the consequences of gender-fluid expression, which has been recognised in academia for years and has become a more discussed topic in mainstream society, but the manner in which the film examines these insights was overlooked. I do this by contextualising the film in terms of contemporary examples of transgender existence, which have brought the topic to mainstream discourse, and by applying gender theory concepts to the film. I discuss the protagonist’s physical and emotional journey to self-discovery in the context of the road movie trope. I then look into the protagonist’s gender performance, as well as how the protagonist negotiates this performance in the various places she visits while on the journey. I show that the film encourages open and honest discourse about gender identity and expression; the opportunity for this discussion was not taken in the year of the film’s release.
“Formação”, uma palavra intransitiva
Authors: Campesato Maria Alice Gouvêa 
Published: May 2018

A formação docente tem sido tema recorrente em produções e pesquisas, no âmbito acadêmico ou fora dele, especialmente na última década. Tal interesse pela temática está articulado a diversos fatores, como a inadequação das escolas às demandas de um mundo cada vez mais veloz
e globalizado e aos resultados dos estudantes nas avaliações de larga escala. Este artigo propõe-se a apresentar um breve panorama da formação docente no Brasil e problematizar alguns de seus aspectos relacionados à contemporaneidade. Para tal, traz um recorte de uma dissertação de mestrado concluída, que investigou as percepções dos professores de uma escola pública do município de Porto Alegre sobre o tempo/espaço em suas articulações com o currículo. Nessa pesquisa foram utilizados, como ferramentas metodológicas, os seguintes mecanismos: grupo focal, entrevistas e análise de alguns documentos da instituição pesquisada. As análises foram realizadas a partir de uma perspectiva foucaultiana. Concluiu-se que a formação é percebida
como de fundamental importância para que a docência, a escola, seus tempos, espaços e currículos possam ser (re)pensados. A formação docente, dessa forma, constitui-se como um espaço coletivo profícuo para o exercício do pensamento e a desnaturalização de conceitos e de
práticas pedagógicas.
Book Review- Endogenous Innovation The Economics of an Emergent System Property
Authors: Buheji Mohamed 
Published: May 2018

Being an expert with claim of being specialized in Economic Competitiveness and Innovation Indexes, I felt ashamed of my huge ignorance in endogenous growth theory and its impact on innovation. Therefore, this review holds a good intention for exploring the essence and the unique characters of the endogenous economic growth which focus on the investment in human capital, innovation, and knowledge-based economy which will lead to economic development. The endogenous innovation was tackled in this work of Antonelli (2017) to show the innovation in the creative reactions and as emergent property of the system. The author tried to illustrate the early relation between the early economics of knowledge and economics of growth, after discussing the limits of the new growth theory. The author managed to show the random events of innovation as creative response.
Democracia, representación y participación ciudadana, a la búsqueda de un equilibrio que la Constitución no logró
Authors: Díaz Revorio Francisco Javier 
Published: May 2018

Resumen:A la hora de regular el modelo de democracia y los mecanismos de participaciónciudadana, la Constitución de 1978 fue conformista y prudente. Estableció un modelo de democracia representativa basado en la posibilidad de elegir representantes cada cuatro años, pero sin especiales fórmulas de control y exigencias de responsabilidad política hacia ellos. Por lo demás, estableció una regulación restrictiva de los instrumentos de democracia directa y semidirecta, en especial del referéndum y de la iniciativa legislativa popular.Cuatro décadas después, las exigencias ciudadanas se han intensificado, generándose un cierto déficit de confianza entre electores y representantes. El trabajo analiza los principales déficits de la Constitución de 1978 en la materia, realizando varias propuestas para mejorar la calidad democrática, que en buena parte implican una amplia reforma constitucional: eliminar las restricciones constitucionales del referéndum y la iniciativa popular, incorporar vías de exigencia de responsabilidad y rendición de cuentas, limitar los mandatos del presidente, asegurar la democracia interna de los partidos políticos, eliminar algunas prerrogativas de los parlamentarios, entre otros.Abstract:When regulating the model of democracy and the mechanisms of citizen participation, the Constitution of 1978 was conformist and prudent. It established a model of representative democracy based on the possibility of electing representatives every four years, but without special formulas of control and demands of political responsibility towards them. Moreover, it established a restrictive regulation of the instruments of direct and semi-direct democracy, especially the referendum and popular legislative initiative. Four decades later, citizen demands have intensified, generating a certain lack of trust between voters and representatives. The paper analyzes the main deficits of the 1978 Constitution in the matter, making several proposals to improve the democratic quality, which in large part imply a broad constitutional reform: eliminate the constitutional restrictions of the referendum and popular initiative, incorporate channels of exigency of responsibility and accountability, limiting the president’s mandates, ensuring the internal democracy of political parties, eliminating some prerogatives of parliamentarians, among others.

Lealtad constitucional y democracia
Authors: Tur Ausina Rosario 
Published: May 2018

Resumen:El presente estudio se enmarca en la problemática de la vigencia y eficacia de la Constitución de 1978 a partir de la configuración dogmática del principio de lealtad. Se parte para ello de un dato relevante: la lealtad no encuentra un acomodo específico en el texto de nuestra Carta Magna, aunque ha sido elaborado doctrinal y jurisprudencialmente en otros sectores del ordenamiento, en otros niveles de gobierno y en el derecho comparado. Sin embargo, su vigencia es evidente e incluso necesaria a la luz de la evolución de nuestro sistema constitucional, sin que este ámbito de estudio haya recibido un análisis detenido por la doctrina. La lealtad se conecta, por ello con un triple postulado: el principio democrático, la supremacía constitucional en perspectiva multinivel, y la doble dimensión formal/material de la Constitución; pero sobre todo confronta y conjuga la necesaria compatibilidad del derecho con la política, y de la ley con la democracia. Desde estas premisas el presente trabajo analiza el origen y evolución del principio, y su fundamento y justificación, para con posterioridad abordar la proyección de la lealtad hacia el ordenamiento, hacia la configuración del poder, y hacia el constitucionalismo multinivel.Abstract:The analysis carried out in this paper addresses the problematic issue of the validity and effectiveness of the 1978 Constitution, on the basis of a dogmatic approach to the loyalty principle. The paper starts with the relevant fact that loyalty cannot be expressly found in the constitutional text of the Spanish Magna Carta, albeit case-law and scholars have developed said concept in other areas of the legal order, for other levels of government and in Comparative Law. Nevertheless, its validity is not only apparent but necessary in light of the evolution of our constitutional system, and yet, this issue has not been thoroughly examined by the legal doctrine. Hence, loyalty is argued to be based on three tenets: the democratic principle, constitutional supremacy from a multi-level perspective, and the twofold formal/material dimension of the Constitution. Above all, the loyalty principle confronts and brings together the much needed compatibility between Law and Politics in addition to that between Law and Democracy. On this basis, the present paper explores not only the origin and evolution of the loyalty principle, but also its basis and rationale, so as to address its role in the legal order and in the context of the configuration of power and of multi-level constitutionalism. Summary:1. Premises. 2. Origin and evolution of the principle of constitutional loyalty. 3. Legal basis and rationale behind the principle of constitutional loyalty. 4. Constitutional loyalty and the legal order. 5. Constitutional loyalty and the exercise of power. 6. Constitutional loyalty in a multi-level system of governance. 7. Conclusions.
¿Qué fue del recurso de amparo ante el Tribunal Constitucional?
Authors: Tenorio Sánchez Pedro Julio 
Published: May 2018

Resumen:El trabajo estudia la evolución y situación actual del recurso de amparo ante el Tribunal Constitucional. Parte de la base de que la cuestión consiste en analizar la aplicación y resultados de la reforma de la Ley Orgánica del Tribunal Constitucional que se realizó en 2007. La reforma se aplicó con algún titubeo inicialmente por parte del Tribunal Constitucional pero finalmente se ha llevado hasta las últimas consecuencias. Esto ha producido un resultado positivo, pues el Tribunal Constitucional está prácticamente al día, muy lejos de la situación de inviabilidad que se dibujaba cuando se concibió la reforma, es decir, en torno al año 2006. Pero la reforma sigue siendo criticada por haber disminuido las garantías del justiciable. Sin embargo, los datos que ofrece en sus Memorias el Tribunal Constitucional permiten constatar que la inmensa mayoría de los recursos se inadmiten por defectuoso planteamiento.El trabajo propone como mejoras el establecimiento de salas de amparo en los Tribunales Superiores de Justicia y en el Tribunal Supremo y el rigor en la exigencia de la invocación del derecho fundamental tan pronto como es vulnerado. Además, considera aconsejable que los abogados no se limiten a la invocación genérica del derecho fundamental, sino que expongan ante la jurisdicción ordinaria el embrión del posible recurso de amparo.Abstract:The article studies the evolution and the current situation of the amparo appeal before the Constitutional Court. The question is to analyze the application and results of the reform of the Constitutional Court Organization Act that was held in 2007. The reform was applied with some hesitation initially by the Constitutional Court but finally has been carried to the last consequences. This has produced a positive result, because the Constitutional Court is practically up to date, very far from the situation of unfeasibility that was drawn when the reform was conceived, that is to say, around the year 2006. But the reform continues being criticized for having diminished the guarantees of the defendant. However, the data that the Constitutional Court offers in its reports allow us to confirm that the vast majority of the appeals are inadmissible due to a defectiveapproach.The work proposes as improvements the establishment of amparo chambers in the Superior Courts of Justice and in the Supreme Court and the rigor in demanding the invocation of the fundamental right as soon as it is violated. In addition, it considers advisable that the lawyers expose before the ordinary jurisdiction the embryo of the possible resource of amparo. Summary:1. Introduction; 2. First period in the interpretation of the reform of 2007: from the promulgation of the law to the ECHR Judgment "Arribas Antón"; 3. Second period in the application of the reform of 2007: from the ECHR Judgment "Arribas Antón" to the present time; 4. Balance of the application of the reform of 2007 ten years after its promulgation; 5. Deception of the justiciables; 6. Possible improvements.
