Investigating the ionization mechanisms powering the extreme emission lines in metal-poor galaxies
C. Daoutis, V. Lebouteiller, D. Schaerer +11
Extreme emission metal-poor galaxies (EEMPGs) are excellent local laboratories for understanding the extreme physical conditions and ionizing radiation fields in the early Universe…
The Evolution of Low-Ionization Electron Densities in Galaxies Across Cosmic Epochs
Mabel G. Stephenson, John Chisholm, Alberto Saldana-Lopez +12
We investigate the low-ionization electron density in the interstellar medium of galaxies across , derived with the [O II] and [S II]$λ\lambda6718…
Unprecedented Constraints on Gas Flows at High Redshift Using Deep JWST/NIRSpec Observations from the LyC22, EXCELS, and AURORA Surveys
Emily Kehoe, Alice E. Shapley, Adam C. Carnall +25
We investigate how low-ionization gas flows in typical star-forming galaxies at depend on galaxy intrinsic properties and viewing angle. For this analysis we use JWST/NIRS…
Chemical composition and kinematics of ionised gas in low-mass star-forming galaxies with extremely high [OIII]/[OII] ratios
Y. I. Izotov, N. G. Guseva, D. Schaerer +1
We present Very Large Telescope/Xshooter spectrophotometric observations of eleven low-redshift (z<0.085) compact star-forming galaxies (`high O32 sample'). These galaxies are char…
Nitrogen abundances in star-forming galaxies 2.2 Gyr after the Big Bang are not elevated
D. Schaerer, Y. I. Izotov, R. Marques-Chaves +22
Using deep medium-resolution JWST rest-optical spectra of a sample of typical star-forming galaxies (Lyman break galaxies and Lyman- emitters) from the LyC22 survey at $z \sim 3…
N-emitters as possible sign-posts of GC formation
D. Schaerer, R. Marques-Chaves, H. Atek +7
Based on the finding of unusual chemical abundance ratios of N-emitters, which resemble those of globular cluster (GC) stars, their compactness, high ISM densities and other proper…
