Abstract
The PRObabilistic Value-added Bright Galaxy Survey (PROVABGS) catalog will provide measurements of galaxy properties, such as stellar mass (M
*), star formation rate (SFR), stellar metallicity (Z), and stellar age (t
age), for >10 million galaxies of the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey. Full posterior distributions of the galaxy properties will be inferred using state-of-the-art Bayesian spectral energy distribution (SED) modeling of DESI spectroscopy and Legacy Surveys photometry. In this work, we present the SED model, the neural emulator for the model, and the Bayesian inference framework of PROVABGS. Furthermore, we apply the PROVABGS SED modeling on realistic synthetic DESI spectra and photometry, constructed using the L-Galaxies semi-analytic model. We compare the inferred galaxy properties to the true values of the simulation using a hierarchical Bayesian framework to quantify accuracy and precision. Overall, we accurately infer the true M
*, SFR, Z, and t
age of the simulated galaxies. However, the priors on galaxy properties induced by the SED model have a significant impact on the posteriors, which we characterize in detail. This work also demonstrates that a joint analysis of spectra and photometry significantly improves the constraints on galaxy properties over photometry alone and is necessary to mitigate the impact of the priors. With the methodology presented and validated in this work, PROVABGS will maximize information extracted from DESI observations and extend current galaxy studies to new regimes and unlock cutting-edge probabilistic analyses. https://github.com/changhoonhahn/provabgs/

Abstract
Protoclusters of galaxies have been found in the last quarter-century. However, most of them have been found through the overdensity of star-forming galaxies, and there have been no known structures identified by more than two spectroscopically confirmed quiescent galaxies at z > 2.5. In this letter, we report the discovery of an overdense structure of massive quiescent galaxies with the spectroscopic redshift z = 2.77 in the COSMOS field, QO-1000. We first photometrically identify this structure as a 4.2σ overdensity with 14 quiescent galaxies in 7 × 4 pMpc2 from the COSMOS2020 catalog. We then securely confirm the spectroscopic redshifts of four quiescent galaxies by detecting multiple Balmer absorption lines with Keck/MOSFIRE. All the spectroscopically confirmed members are massive (

) and located in a narrow redshift range (2.76 < z < 2.79). Moreover, three of them are in the 1 × 1 pMpc2 in the transverse direction at the same redshift (z = 2.760–2.763). Such a concentration of four spectroscopically confirmed quiescent galaxies implies that QO-1000 is >68 times denser than the general field. In addition, we confirm that they form a red sequence in the J − K

at z = 0. These results suggest that QO-1000 is a more mature protocluster than the other known protoclusters. It is likely in a transition phase between star-forming protoclusters and quenched galaxy clusters.

Abstract
EX Lup is a low-mass pre-main-sequence star that occasionally shows accretion-related outbursts. Here, we present JWST/MIRI medium-resolution spectroscopy obtained for EX Lup 14 yr after its powerful outburst. EX Lup is now in quiescence and displays a Class II spectrum. We detect a forest of emission lines from molecules previously identified in infrared spectra of classical T Tauri disks: H2O, OH, H2, HCN, C2H2, and CO2. The detection of organic molecules demonstrates that they are back after disappearing during the large outburst. Spectral lines from water and OH are for the first time deblended and will provide a much-improved characterization of their distribution and density in the inner disk. The spectrum also shows broad emission bands from warm, submicron-size amorphous silicate grains at 10 and 18 μm. During the outburst, in 2008, crystalline forsterite grains were annealed in the inner disk within 1 au, but their spectral signatures in the 10 μm silicate band later disappeared. With JWST we rediscovered these crystals via their 19.0, 20.0, and 23.5 μm emission, the strength of which implies that the particles are at ∼3 au from the star. This suggests that crystalline grains formed in 2008 were transported outwards and now approach the water snowline, where they may be incorporated into planetesimals. Containing several key tracers of planetesimal and planet formation, EX Lup is an ideal laboratory to study the effects of variable luminosity on the planet-forming material and may provide an explanation for the observed high crystalline fraction in solar system comets.
Constraints on the Size and Composition of the Ancient Martian Atmosphere from Coupled CO2–N2–Ar Isotopic Evolution Models
Authors: Thomas Trent B. , Hu Renyu , Lo Daniel Y. 
Published: March 2023

Abstract
Present-day Mars is cold and dry, but mineralogical and morphological evidence shows that liquid water existed on the surface of ancient Mars. In order to explain this evidence and assess ancient Mars’s habitability, one must understand the size and composition of the ancient atmosphere. Here we place constraints on the ancient Martian atmosphere by modeling the coupled, self-consistent evolution of atmospheric CO2, N2, and Ar on Mars from 3.8 billion years ago (Ga) to the present. Our model traces the evolution of these species’ abundances and isotopic composition caused by atmospheric escape, volcanic outgassing, and crustal interaction. Using a Markov Chain Monte Carlo method to explore a plausible range of parameters, we find hundreds of thousands of model solutions that recreate the modern Martian atmosphere. These solutions indicate that Mars’s atmosphere contained 0.3–1.5 bar CO2 and 0.1–0.5 bar N2 at 3.8 Ga. The global volume of deposited carbonates critically determines the ancient atmospheric composition. For example, a ∼1 bar CO2 ancient atmosphere with 0.2–0.4 bar N2 requires ∼0.9 bar CO2 deposited in carbonates primarily in open-water systems. With the joint analysis of C, N, and Ar isotopes, we refine the constraints on the relative strengths of outgassing and sputtering, leading to an indication of a reduced early mantle from which the outgassing is sourced. Our results indicate that a CO2–N2 atmosphere with a potential H2 component on ancient Mars is consistent with Mars’s geochemical evolution and may explain the evidence for its past warm and wet climate.

Dysbiosis has been implicated in childhood obesity. Oral intake of fermented milk containing Lacticaseibacillus casei strain Shirota preserves gut microbiota (GM) diversity in children and adults. This study was a double-blind trial involving 37 overweight or obese children aged 6-10 years. Children were followed over a 6-week intervention period in which they received different fermented milk products containing L. casei Shirota: 10 in the first group received just L. casei Shirota; 13 received L. casei Shirota with 3 g/day of inulin (L. casei+inulin); and 14 received L. casei Shirota with 3 g/day of fructans from Agave salmiana (L. casei+fructans). Principal component analysis showed the relationship between microbial abundance, GM metabolites, and other obesity-related markers. Supplementation with probiotics and synbiotics improved the HDL-cholesterol levels of overweight and obese children, although no changes in body composition were detected. We observed an increase in butyrate or propionate concentrations in the L. casei+fructans group compared to the end of the intervention (P<0.03). A diminished level of ANGPTL4 within the L. casei+fructans group (P=0.04) was also found, but no differences when lipopolysaccharide-binding protein was evaluated. The FFAR2+ cell frequency decreased between baseline and at the end of 6-week intervention in L. casei+inulin (P=0.02) and L. casei+fructans groups (P=0.04). In contrast, the percentage of CD14+FFAR3+ frequency increased in the same groups (P=0.04). The L. casei Shirota with inulin or fructans modulates GM, which improves the lipid profile and changes at a molecular level, such as expression of FFAR3 and FFAR2, ANGPTL4, propionate, and butyrate. It, therefore, could be considered an interesting therapeutic possibility for treating childhood overweight and obesity.
The study was registered at ClinicalTrials.gov (ID: NCT05423015).
La partie de cache-cache la plus longue du monde. Auteurs médiévaux contre critiques modernes
Authors: Martina Piero Andrea , Trachsler Richard 
Published: March 2023

C’est en partant de la considération qu’une bonne partie de la production littéraire médiévale nous est parvenue dans des textes sans nom d’auteur que s’est imposé le cliché du Moyen Âge aux écrivains humbles, qui hésitent à signer leurs œuvres, cliché auquel on oppose traditionnellement l’autre cliché, celui de la Renaissance aux artistes désormais conscients et fiers de leur individualité, qui apposent à leurs créations originelles une signature. Dans cet article, nous nous proposons de revenir sur la question du nom de l’auteur médiéval, pour rappeler que tout, ou presque, est affaire de critique : qu’il s’agisse de sortir un texte de l’anonymat pour le placer sous l’autorité d’un écrivain célèbre ou de déclarer qu’un patronyme est en réalité un pseudonyme, ou encore de faire émerger un nom à partir d’une nuée de lettres en les organisant en anagramme, c’est le médiéviste qui tranche. En nous arrêtant sur les cas de Marie de France et, surtout, de Jean Renart, nous nous proposons de parcourir une partie de l’histoire de la critique, pour voir comment l’histoire de la discipline pèse toujours sur l’approche de nos études médiévales.
La solidarité écologique, lien de droit d’une interdépendance au vivant
Authors: Barrière Olivier 
Published: March 2023

Le législateur français introduit le concept de solidarité écologique dans le droit en 2006 comme une relation bioécologique entre espaces, puis ce concept est érigé en principe général en 2016 dans le code de l’environnement en appelant à prendre en compte dans les prises de décisions « les interactions des écosystèmes, des êtres vivants et des milieux naturels ou aménagés ». Même avec une définition restrictive de la solidarité écologique, évitant de mentionner toute interdépendance, son introduction dans la loi est un pas majeur vers un dépassement qui va permettre une transformation indispensable de la société moderne occidentale face à l’urgence écologique (climatique, sanitaire, de biodiversité). L’analyse de l’apport de cette solidarité des êtres vivants doit être perçue comme un cheval de Troie dans l’antre du naturalisme. Le droit étatique va devoir se réinventer en se dégageant d’un schéma de développement. Il doit opérer une mutation articulée autour d’une ontologie relationnelle commune, dite « coviabiliste », inscrite dans le cadre d’un pluralisme juridique. Cette réinvention du droit ne peut se réaliser qu’en rapprochant les sociétés du vivant, humains et autres qu’humains, faisant socio-écosystème. La solidarité écologique ouvre les perspectives d’un droit de la coviabilité en formalisant les interactions au sein des êtres vivants et des milieux par le biais du lien de viabilité, comme lien de droit.
