Abstract
This study comprehensively investigates the gamma-ray dim population of Fanaroff–Riley Type 0 (FR0) radio galaxies as potentially significant sources of ultra–high energy cosmic rays (UHECRs, E > 1018 eV) detected on Earth. While individual FR0 luminosities are relatively low compared to the more powerful Fanaroff–Riley Type 1 and Type 2 galaxies, FR0s are substantially more prevalent in the local universe, outnumbering the more energetic galaxies by a factor of ∼5 within a redshift of z ≤ 0.05. Employing CRPropa3 simulations, we estimate the mass composition and energy spectra of UHECRs originating from FR0 galaxies for energies above 1018.6 eV. This estimation fits data from the Pierre Auger Observatory (Auger) using three extensive air shower models; both constant and energy-dependent observed elemental fractions are considered. The simulation integrates an approximately isotropic distribution of FR0 galaxies, extrapolated from observed characteristics, with UHECR propagation in the intergalactic medium, incorporating various plausible configurations of extragalactic magnetic fields, both random and structured. We then compare the resulting emission spectral indices, rigidity cutoffs, and elemental fractions with recent Auger results. In total, 25 combined energy-spectrum and mass-composition fits are considered. Beyond the cosmic-ray fluxes emitted by FR0 galaxies, this study predicts the secondary photon and neutrino fluxes from UHECR interactions with intergalactic cosmic photon backgrounds. The multimessenger approach, encompassing observational data and theoretical models, helps elucidate the contribution of low-luminosity FR0 radio galaxies to the total cosmic-ray energy density.
More Likely Than You Think: Inclination-driving Secular Resonances Are Common in Known Exoplanet Systems

Published: December 2024

Abstract
Multiplanet systems face significant challenges to detection. For example, farther-orbiting planets have a reduced signal-to-noise ratio in radial velocity detection methods, and small mutual inclinations between planets can prevent them from all transiting. One mechanism for exciting mutual inclination between planets is secular resonance, where the nodal precession frequencies of the planets align so as to greatly increase the efficiency of the angular momentum transport between planets. These resonances can significantly misalign planets from one another, hindering detection, and typically can only occur when there are three or more planets in the system. Naively, systems can only be in resonance for particular combinations of planet semimajor axes and masses; however, effects that alter the nodal precession frequencies of the planets, such as the decay of stellar oblateness, can significantly expand the region of parameter space where resonances occur. In this work, we explore known three-planet systems, determine whether they are in (or were in) secular resonance due to evolving stellar oblateness, and demonstrate the implications of resonance on their detectability and stability. We show that about 20% of a sample of three-planet transiting systems seem to undergo these resonances early in their lives.

Abstract
Spatially resolved emission-line kinematics are invaluable for investigating fundamental galaxy properties and have become increasingly accessible for galaxies at z ≳0.5 through sensitive near-infrared imaging spectroscopy and millimeter interferometry. Kinematic modeling is at the core of the analysis and interpretation of such data sets, which at high z present challenges due to the lower signal-to-noise ratio (S/N) and resolution compared to the data of local galaxies. We present and test the 3D fitting functionality of DysmalPy, examining how well it recovers the intrinsic disk rotation velocity and velocity dispersion, using a large suite of axisymmetric models, covering a range of galaxy properties and observational parameters typical of z ∼ 1−3 star-forming galaxies. We also compare DysmalPy’s recovery performance to that of two other commonly used codes, GalPak

3D and 3D
Barolo, which we use in turn to create additional sets of models to benchmark DysmalPy. Over the ranges of S/N, resolution, mass, and velocity dispersion explored, the rotation velocity is accurately recovered by all tools. The velocity dispersion is recovered well at high S/N, but the impact of methodology differences is more apparent. In particular, template differences for parametric tools and S/N sensitivity for the nonparametric tool can lead to differences of up to a factor of 2. Our tests highlight and the importance of deep, high-resolution data and the need for careful consideration of (i) the choice of priors (parametric approaches); and (ii) the masking (all approaches); and (iii), more generally, the evaluating of the suitability of each approach to the specific data at hand. This paper accompanies the public release of DysmalPy.
A Framework to Calibrate a Semianalytic Model of the First Stars and Galaxies to the Renaissance Simulations

Published: December 2024

Abstract
We present a method that calibrates a semianalytic model to the Renaissance Simulations, a suite of cosmological hydrodynamical simulations with high-redshift galaxy formation. This approach combines the strengths of semianalytic techniques and hydrodynamical simulations, enabling the extension to larger volumes and lower redshifts that are inaccessible to simulations due to computational expense. Using a sample of Renaissance star formation histories from an average density region of the Universe, we construct a four-parameter prescription for metal-enriched star formation characterized by an initial bursty stage followed by a steady stage where stars are formed at constant efficiencies. Our model also includes a treatment of Pop III star formation where a minimum halo mass and log-normal distribution of stellar mass are adopted to match the numerical simulations. Star formation is generally well reproduced for halos with masses ≲109
M
⊙. Between 11 < z < 25 our model produces metal-enriched star formation rate densities (SFRDs) that typically agree with Renaissance within a factor of ∼2 for the average density region. Additionally, the total metal-enriched stellar mass only differs from Renaissance by about 10% at z ∼ 11. For regions that are either more overdense or rarefied and not included in the calibration, we produce metal-enriched SFRDs that agree with Renaissance within a factor of ∼2 at high-z but eventually differ by higher factors for later times. This is likely due to environmental dependencies not included in the model. Our star formation prescriptions can easily be adopted in other analytic or semianalytic works to match our calibration to Renaissance.
A Systematic Survey of Moon-forming Giant Impacts. II. Rotating Bodies
Authors: Meier Thomas , Reinhardt Christian , Timpe Miles , Stadel Joachim , Moore Ben 
Published: December 2024

Abstract
In the leading theory of lunar formation, known as the giant impact hypothesis, a collision between two planet-sized objects resulted in a young Earth surrounded by a circumplanetary debris disk from which the Moon later accreted. The range of giant impacts that could conceivably explain the Earth–Moon system is limited by the set of known physical and geochemical constraints. However, while several distinct Moon-forming impact scenarios have been proposed—from small, high-velocity impactors to low-velocity mergers between equal-mass objects—none of these scenarios have been successful at explaining the full set of known constraints, especially without invoking one or more controversial post-impact processes. Allowing for pre-impact rotation of the colliding bodies has been suggested as an avenue that may produce more promising collision outcomes. However, to date, only limited studies of pre-impact rotation have been conducted. Therefore, in this second paper of the series, we focus on pairwise impacts between rotating bodies. Using nonrotating collisions as a baseline, we systematically study the effects of rotation on collision outcomes. We consider nine distinct rotation configurations and a range of rotation rates up to the rotational stability limit. Notably, we identify a population of collisions that can produce low post-impact angular momentum (AM) budgets and massive, iron-poor protolunar disks. Furthermore, even when pre-impact rotation is included, we demonstrate that the canonical Moon-forming impact can only generate sufficiently massive protolunar disks in the presence of excessive post-impact AM budgets; this casts doubt on the canonical impact scenario.

Abstract
Radio halos of edge-on galaxies are crucial for investigating cosmic ray propagation and magnetic field structures in galactic environments. We present VLA C-configuration S-band (2–4 GHz) observations of the spiral galaxy NGC 3556, a target from the Continuum Halos in Nearby Galaxies—an EVLA Survey. We estimate the thermal contribution to the radio emission from a combination of the Hα and mid-IR data, and employ rotation measure synthesis to reveal the magnetic field structures. In our data, NGC 3556 exhibits a box-like radio halo extending nearly 7 kpc from the galactic plane. The scale height of the total S-band intensity in the halo is 1.68 ± 0.29 kpc, while that of the nonthermal intensity is 1.93 ± 0.28 kpc. Fitting the data to a 1D cosmic-ray transport model, we find advection to describe the cosmic-ray propagation within the halo better than diffusion, with advection speeds of 245 ± 15 km s−1 and 205 ± 25 km s−1 above and below the disk, respectively. The magnetic field is detected patchily across the galaxy, displaying a toroidal configuration in the rotation measure map. The mean equipartition magnetic field strength is approximately 8.3 μG in the disk and 4.5 μG in the halo. In addition, a bubble-like structure extends nearly 3 kpc into the southern halo, aligned with the polarized intensity and Hα image, suggestive of superwinds generated by recent star formation feedback in the nuclear region.
V1663 Aquilae: A Fast Fe ii-type Nova that Formed Dust and Coronal Lines
Authors: Rudy Richard J. , Russell Ray W. , Lynch David K. , Puetter R. C. 
Published: December 2024

Abstract
V1663 Aquilae was a rare nova that formed both dust and coronal emission lines. A spectrum from 157 days after peak brightness shows both thermal dust emission and coronal emission present at the same epoch. An earlier spectrum from 36 days post maximum captures the nova prior to the formation of either dust or high-excitation emission lines. At the earlier epoch, its emission lines arose mostly from neutral species and singly ionized iron.
Vegetation of the southern slopes of Mt. Damavand, Iran: a comprehensive phytosociological classification

Published: December 2024

Aims: To provide the first syntaxonomic scheme of the main natural and semi-natural steppic vegetation types along a 3000-m elevational gradient. Location: South-facing slopes of Mt. Damavand, Iran. Methods: A dataset of 330 phytosociological plots of 25 m2 sampled in all main vegetation types of the region was subjected to unsupervised classification with TWINSPAN. After some manual adjustments to maximise the floristic distinctness of clusters, the resulting units were translated into syntaxa at the class, order, alliance and association level. Diagnostic species were determined with phi values as measure of fidelity. The differences in abiotic and vegetation parameters among associations/communities were visualised with boxplots and the environmental gradients associated with the community differentiation via detrended correspondence analysis (DCA). Results: We found four main groups that are ecologically well interpretable and considered at the level of phytosociological classes: rocky habitats (Tanacetalia kotschyi, class unknown), scree habitats (Didymophyso aucheri-Dracocephaletea aucheri), snow-beds (Salicetea herbaceae) and grasslands (Astragalo-Brometea). We distinguished six orders, nine alliances and 18 association-level communities, which were floristically well separated. Many of these syntaxa were new to science. Elevation was the main driver of species composition and formation of the major vegetation groups. Conclusions: This study contributes to advancing the syntaxonomic understanding of the vegetation of Iran. It is particularly valuable as it covers the complete elevational gradient of 3000 m and thus also comprehensively includes the vegetation types of the lower elevations that previously had been rarely studied syntaxonomically in Iran. Furthermore, this study is the first to examine mown (semi-natural) tall herb rich grasslands in Iran, which were assigned to the new alliance Cousinion petrocauli. Since our study was based on a regionally constrained dataset, we could not solve all syntaxonomic issues conclusively. This underscores the need for more comprehensive studies of the vegetation in the entire Alborz Mts as well as other Iranian mountain ranges in the future.

African vegetation studies: introduction to a Special Collection
Authors: Guuroh Reginald T. , Brown Leslie R. , Alvarez Miguel , Finckh Manfred , Schmiedel Ute , Tsheboeng Gaolathe , Dengler Jürgen 
Published: December 2024

Abstract: This editorial introduces the Special Collection of “African Vegetation Studies”. The collection includes seven research papers from four African countries. One paper examines the impact of traditional agro-ecosystems on plant diversity in Morocco. In Benin, one research paper focuses on vegetation associations in a biosphere reserve, and another is on land cover changes on inselbergs. In Namibia, one paper provides a syntaxonomic description of the Karstveld vegetation, while another models potential vegetation changes along a south-north rainfall gradient. Two papers present research on vegetation classification and descriptions of two natural areas in South Africa, namely the Tankwa Karoo National Park and the Telperion Nature Reserve. The collection demonstrates that there are important classification studies ongoing in different parts of the continent to better understand the diversity and complexity of African vegetation. At the same time our mini-review of the current status of vegetation classification and vegetation-plot databases in Africa highlights that much work remains to be done to achieve a comprehensive and internationally consistent vegetation classification for the countries of Africa, which would be beneficial for land use management, biodiversity conservation and ecological research.

Ce qui manque : explorer l’utilisation de photographies dans la « perlaboration » du corps de naissance avec les jeunes transgenres
Authors: Lemma Alessandra 
Published: December 2024

Cet article se concentre sur la manière dont, pour certains jeunes qui s’identifient comme transgenres, l’anticipation et/ou le véritable processus de transition représente(nt) un mouvement d’éloignement de quelque chose en elleux-mêmes ressenti comme faux, douloureux, ou traumatique, et qui n’a pas encore été reconnu consciemment comme tel. Ceci devient une partie « manquante » de l’expérience du self, enfermée dans le corps. Je suggère que le processus d’identification et de restitution de la partie « manquante » exige de perlaborer le corps de naissance au sens métaphorique et littéral, au service de l’expansion du choix autonome sur la manière de trouver un lieu à soi 2 hospitalier dans le corps. M’appuyant sur les trois « faits de la vie » fondamentaux de Roger Money-Kyrle, j’en propose un quatrième, à savoir le fait inéluctable de notre corporéité, pour souligner que notre histoire personnelle inclut toujours notre histoire corporelle, d’où l’importance de perlaborer ce que le corps de naissance représente inconsciemment. Je décris l’utilisation de photographies au cours de la psychothérapie psychanalytique de jeunes ayant entrepris une transition sociale, afin de travailler sur les représentations visuelles du corps de naissance dans le but de faciliter la perlaboration, au sens psychanalytique, du récit inconscient du corps de naissance. Je suggère que le déploiement de ce mode visuel peut être particulièrement utile pour impliquer des jeunes du spectre autistique, qui représentent de nos jours une minorité significative des jeunes transgenres.

Cette contribution se prête à l’exercice d’une anthropologie plastique en proposant une nouvelle de science-fiction (ou de linguistique-fiction), « Un dialogue particulier », où l'autrice imagine une ethnographie du boson de Higgs : une particule élémentaire dont l’existence a été confirmée par l’Organisation européenne pour la recherche nucléaire (CERN) en 2012 avec le plus grand accélérateur de particules au monde, le Grand collisionneur de hadrons (LHC). Cette nouvelle est suivie d’un commentaire, intitulé « Note de l’autrice : Comment dialoguer avec une particule ? », afin de révéler les thématiques anthropologiques sous-jacentes à son artifice d’écriture.
Inventer des « dispositifs génératifs » à la croisée de l’ethnographie et du design
Authors: Milliot Virginie , Paté Léna 
Published: December 2024

Cet article revient sous forme dialogique sur une collaboration entre ethnographie et design. Virginie Milliot et Léna Paté ont organisé, dans le mouvement d’une enquête en cours sur les pratiques du Vieux Marché à Bruxelles, le festival « Histoires de Brol ». Elles reviennent sur la manière dont elles ont travaillé à la croisée de leurs deux disciplines pour imaginer une méthode hybride. Dans le processus collaboratif qu’elles ont conçu, les outils du design suivent au plus près les intrigues du terrain pour donner forme à un « dispositif génératif » de réflexion collective.
Dispositifs à variables inconnues
Authors: Grimaud Emmanuel 
Published: December 2024

Jeux de rôle, scénarios spéculatifs d’interaction, machines décalées, plateformes expérimentales ou dispositifs d’expérience peuvent produire des effets de réinitialisation d’un problème ou d’une question, même (et surtout si) on n’en maîtrise pas toutes les variables. Plutôt qu’une anthropologie au service du design (for design), une anthropologie du design (of design) ou un design au service de l’anthropologie (design for anthropology) (Murphy, 2016), cet article propose une autre voie : expérimenter aux limites du design une foule de dispositifs à variables inconnues, échappant à l’alternative entre une conception « dure » ou « sauvage » de l’expérience. IA et cinéma sont vus dans ce contexte comme deux phases historiques d’un même programme plastique qui a commencé le jour où les modernes ont décidé que nos yeux ne nous suffisaient plus et qu’il nous fallait voir à travers « un œil aux propriétés analytiques inhumaines » (Epstein). Il s’agit de comprendre les ressorts de ce drôle de programme inachevé, de se situer par rapport à lui, d’en faire l’examen de conscience, d’en jouer plutôt que d’en être le jouet ou de le dépasser.

La bibliothèque de Vladimir Tukalevskij. L’exil et ses avatars, de Terijoki à Prague (1913-1936)
Authors: Cirac Stéphanie 
Published: December 2024

En 1923, Vladimir Tukalevskij (1881-1936) emporta dans son exil pragois sa bibliothèque, riche de plusieurs milliers de volumes. Cette migration fut géographique, mais aussi politique et institutionnelle : une fois installée dans la capitale tchécoslovaque, la bibliothèque continua d’évoluer, passant par différentes tutelles avant de participer à la fondation de la Bibliothèque slave sous la direction du ministère des Affaires étrangères tchécoslovaques. Au gré de ses pérégrinations, confirmant sa position centrale dans la vie scientifique russe en exil et dans la slavistique européenne, elle fut le témoin de la fragilité des institutions de la Russie de l’étranger, comme l’illustre le destin tragique de Vladimir Tukalevskij.
Können frauen genies werden ?La catégorisation genrée des écrivaines dans le champ de la modernité intellectuelle et littéraire germanophone
Authors: Rosso Alexia 
Published: December 2024

Dans cet article, nous mobilisons le genre comme catégorie d’analyse pour nous interroger sur l’écriture de l’histoire littéraire de la modernité germanophone à partir de deux revues culturelles allemandes publiées au tournant des xixe et xxe siècles : Die Gesellschaft et Freie Bühne für modernes Leben/Neue Deutsche Rundschau. En nous appuyant sur ces deux supports, nous évaluons dans quelle mesure la conception alors majoritairement différentialiste des rapports sociaux de sexe a pu informer la manière dont les écrivaines ont été catégorisées dans le champ littéraire et intellectuel entre 1890 et 1902. Replacées dans leur contexte historique et idéologique de publication, ces revues nous donnent en effet un aperçu des différentes visions des rapports sociaux de sexe véhiculées dans les milieux cultivés allemands (Bildungsbürgertum). Il s’agit alors de poser la question de la dimension instituante de ces visions dans les processus de catégorisation des écrivaines à cette période.
