The Qz5 Survey (II): Metallicity Evolution of Damped Lyα Systems Out to z5
Marie Wisz, Marc Rafelski, Grecco Oyarzun +10
Damped Ly absorbers (DLAs) are the highest \HI\ column density (\NHI) absorption line systems detected in the spectra of background quasars. DLAs dominate the neutral gas conte…
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…
Power-law Emission-line Wings and Radiation-Driven Superwinds in Local Lyman Continuum Emitters
Lena Komarova, Sally Oey, Rui Marques-Chaves +27
We investigate broad emission-line wings, reaching , observed in 26 galaxies with Lyman continuum (LyC) observations, primarily from the Low-redshift Lyman C…
The Qz5 Survey (I): How the HI Mass Density of the Universe Evolves With Cosmic Time
Grecco A. Oyarzún, Marc Rafelski, Lise Christensen +9
We report that the neutral hydrogen (HI) mass density of the Universe () increases with cosmic time since , peaks at , and then decreases toward $z \si…
The Low-Redshift Lyman Continuum Survey: The Roles of Stellar Feedback and ISM Geometry in LyC Escape
Sophia R. Flury, Anne E. Jaskot, Alberto Saldana-Lopez +30
One of the fundamental questions of cosmology is the origin and mechanism(s) responsible for the reionization of the Universe beyond . To address this question, many studie…
Multivariate Predictors of LyC Escape II: Predicting LyC Escape Fractions for High-Redshift Galaxies
Anne E. Jaskot, Anneliese C. Silveyra, Anna Plantinga +19
JWST is uncovering the properties of ever increasing numbers of galaxies at z>6, during the epoch of reionization. Connecting these observed populations to the process of reionizat…
