Detecting and Characterizing Mg II absorption in DESI Survey Validation Quasar Spectra

Lucas Napolitano, Agnesh Pandey, Adam D. Myers +33

We present findings of the detection of Magnesium II (Mg II, λ = 2796, 2803 Å) absorbers from the early data release of the Dark Energy Spectroscopic Instrument (DESI). DESI is pro…

The DESI Survey Validation: Results from Visual Inspection of the Quasar Survey Spectra

David M. Alexander, Tamara M. Davis, E. Chaussidon +69

A key component of the Dark Energy Spectroscopic Instrument (DESI) survey validation (SV) is a detailed visual inspection (VI) of the optical spectroscopic data to quantify key sur…

Shattering as a source of small grains in the circum-galactic medium

Hiroyuki Hirashita, Ting-Wen Lan

Observed reddening in the circum-galactic medium (CGM) indicates a significant abundance of small grains, of which the origin is still to be clarified. We examine a possible path o…

A comparative study of satellite galaxies in Milky Way-like galaxies from HSC, DECaLS and SDSS

Wenting Wang, Masahiro Takada, Xiangchong Li +10

We conduct a comprehensive and statistical study of the luminosity functions (LFs) for satellite galaxies, by counting photometric galaxies from HSC, DECaLS and SDSS around isolate…

The Co-Evolution of Galaxies and the Cool Circumgalactic Medium Probed with the SDSS and DESI Legacy Imaging Surveys

Ting-Wen Lan

We study the evolution of galaxies and the circumgalactic medium (CGM) through cosmic time by correlating MgII absorbers, tracers of cool gas (~K), detecte…

Understanding the circumgalactic medium is critical for understanding galaxy evolution

Molly S. Peeples, Peter Behroozi, Rongmon Bordoloi +69

Galaxies evolve under the influence of gas flows between their interstellar medium and their surrounding gaseous halos known as the circumgalactic medium (CGM). The CGM is a major…
