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 conten…
MXDFz4.4: A LyC emitter 250Myr after the epoch of reionization and a first test of Ly-alpha morphology as a tracer of LyC escape at high redshift
Ilias Goovaerts, Marc Rafelski, Alexander Beckett +14
Assessing the contribution of ionizing sources to cosmic reionization is a central goal of extragalactic astrophysics. Understanding and quantifying ionizing escape remains challen…
A survey of Ly emission around Damped Ly absorbers at with the Keck Cosmic Web Imager
Grecco A. Oyarzun, Marc Rafelski, Nissim Kanekar +3
We present Keck Cosmic Web Imager (KCWI) Ly integral field spectroscopy of the fields surrounding 14 Damped Ly absorbers (DLAs) at . Of these 14 DLAs, 9 have hig…
SDSS-IV MaNGA: The effect of stellar mass and halo mass on the assembly histories of satellite galaxies
Grecco A. Oyarzun, Kevin Bundy, Kyle B. Westfall +5
We combine an unprecedented MaNGA sample of over 3,000 passive galaxies in the stellar mass range 10^{9}-10^{12} Msun with the Sloan Digital Sky Survey group catalog by Tinker to q…
A Comprehensive Study of Ly Emission in the High-redshift Galaxy Population
Grecco A. Oyarzún, Guillermo A. Blanc, Valentino González +2
We present an exhaustive census of Lyman alpha (Ly) emission in the general galaxy population at . We use the Michigan/Magellan Fiber System (M2FS) spectrograph to stud…
How Lyman Alpha Emission Depends On Galaxy Stellar Mass
Grecco A. Oyarzún, Guillermo A. Blanc, Valentino González +6
In this work, we show how the stellar mass (M) of galaxies affects the 3<z<4.6 Ly-alpha equivalent width (EW) distribution. To this end, we design a sample of 629 galaxies in the M…
