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…

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…
