Resolving the Assembly of Disk Galaxies from the Epoch of Reionisation to Cosmic Noon
Melanie Kaasinen, Mahsa Kohandel, Francesca Rizzo +45
Most of the mass and angular momentum of today's disk galaxies assembled at . Yet, it remains unclear how these galaxies acquired their gas, how their baryons and dark matter…
Unified modelling of broad and narrow optical-UV emission lines from massive black holes: interpreting high-redshift JWST observations
Adele Plat, Michaela Hirschmann, Emma Curtis-Lake +10
JWST is uncovering a large population of active galactic nuclei (AGN) at high redshift, motivating the extension of models calibrated on local sources to a broader range of physica…
Well-being and career instability across genders in the Spanish Astronomical Society
Maritza A. Lara-Lopez, I. Rebollido, A. Vidal-Garcia +9
We present the results of a comprehensive survey conducted among members of the Spanish Astronomical Society (Sociedad Espanola de Astronomia, SEA) to assess well-being, profession…
Significant Evidence of an AGN Contribution in GHZ2 at z = 12.34
Oscar A. Chavez Ortiz, Steven L. Finkelstein, Adele Plat +18
GHZ2 is among the highest-redshift galaxies discovered to date, exhibiting a spectrum rich with prominent emission lines in the rest-frame ultraviolet (UV) and optical. These featu…
Widespread Hot Molecular Gas Heated by Shear-induced Turbulence in the Galactic Center
Juan Li, Junzhi Wang, Zhiqiang Shen +13
We observed NH3 metastable inversion lines from (3, 3) to (18, 18) toward G0.66-0.13 in the Galactic center with the Shanghai Tianma 65m radio telescope and Yebes 40 m telescope. H…
A variable active galactic nucleus at triply-imaged by the galaxy cluster MACS J0035.4-2015
Lukas J. Furtak, Ramesh Mainali, Adi Zitrin +32
We report the discovery of a triply imaged active galactic nucleus (AGN), lensed by the galaxy cluster MACS J0035.4-2015 (). The object is detected in Hubble…
Emission-line properties of IllustrisTNG galaxies: from local diagnostic diagrams to high-redshift predictions for JWST
Michaela Hirschmann, Stephane Charlot, Anna Feltre +8
We compute synthetic, rest-frame optical and ultraviolet (UV) emission-line properties of galaxy populations at redshifts from z0 to z=8 in a full cosmological framework.…
The Art of Measuring Physical Parameters in Galaxies: A Critical Assessment of Spectral Energy Distribution Fitting Techniques
Camilla Pacifici, Kartheik G. Iyer, Bahram Mobasher +52
The study of galaxy evolution hinges on our ability to interpret multi-wavelength galaxy observations in terms of their physical properties. To do this, we rely on spectral energy…
Self-generated ultraviolet radiation in molecular shock waves II. CH+ and the interpretation of emission from shock ensembles
Andrew Lehmann, Benjamin Godard, Gillaume Pineau des Forêts +2
Shocks, modelled over a broad range of parameters, are used to construct a new tool to deduce the mechanical energy and physical conditions from observed atomic or molecular emissi…
Stars and gas in the most metal-poor galaxies I: COS and MUSE observations of SBS 0335-052E
A. Wofford, A. Vidal-García, A. Feltre +5
Among the nearest most metal-poor starburst-dwarf galaxies known, SBS 0335-052E is the most luminous in integrated nebular He II λ4686 emission. This makes it a unique target to te…
Ultraviolet spectra of extreme nearby star-forming regions: evidence for an overabundance of very massive stars
Peter Senchyna, Daniel P. Stark, Stéphane Charlot +3
As deep spectroscopic campaigns extend to higher redshifts and lower stellar masses, the interpretation of galaxy spectra depends increasingly upon models for very young stellar po…
Extremely metal-poor galaxies with HST/COS: laboratories for models of low-metallicity massive stars and high-redshift galaxies
Peter Senchyna, Daniel P. Stark, Jacopo Chevallard +3
Ultraviolet (UV) observations of local star-forming galaxies have begun to establish an empirical baseline for interpreting the rest-UV spectra of reionization-era galaxies. Howeve…
Are LGRBs biased tracers of star formation? Clues from the host galaxies of the /BAT6 complete sample of bright LGRBs III: Stellar masses, star formation rates and metallicities at
J. T. Palmerio, S. D. Vergani, R. Salvaterra +11
(Abridged) Long gamma-ray bursts (LGRB) have been suggested as promising tracers of star formation owing to their association with the core-collapse of massive stars. The goal of t…
Physical properties and H-ionizing-photon production rates of extreme nearby star-forming regions
Jacopo Chevallard, Stéphane Charlot, Peter Senchyna +7
Measurements of the galaxy UV luminosity function at z>6 suggest that young stars hosted in low-mass star-forming galaxies produced the bulk of hydrogen-ionizing photons necessary…
Modelling ultraviolet-line diagnostics of stars, the ionized and the neutral interstellar medium in star-forming galaxies
A. Vidal-García, S. Charlot, G. Bruzual +1
We combine state-of-the-art models for the production of stellar radiation and its transfer through the interstellar medium (ISM) to investigate ultraviolet-line diagnostics of sta…
