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…
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…
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…
Feedback and dynamical masses in high- galaxies: the advent of high-resolution NIRSpec spectroscopy
A. Saldana-Lopez, J. Chisholm, S. Gazagnes +11
Stellar feedback is an essential step in the baryon cycle of galaxies, but it remains unconstrained beyond Cosmic Noon. We study the ionized gas kinematics, dynamical mass and gas-…
A great diversity of spectral shapes in the ionising spectra of z ~ 0.6-1 galaxies revealed by HST/COS and possible detection of nebular LyC emission
Y. I. Izotov, D. Schaerer, G. Worseck +4
We present observations of eleven compact star-forming galaxies in the redshift range z = 0.6145 - 1.0053, with the Cosmic Origins Spectrograph (COS) on board the Hubble Space Tele…
