DESI Mg II Absorbers: Extinction Characteristics & Quasar Redshift Accuracy
Lucas Napolitano, Adam D. Myers, Vicky Fawcett +32
In this paper, we study how absorption-line systems affect the spectra and redshifts of quasars (QSOs), using catalogs of Mg II absorbers from the early data release (EDR) and firs…
Constraining the phase shift of relativistic species in DESI BAOs
Abbé M. Whitford, Hugo Rivera-Morales, Cullan Howlett +36
In the early Universe, neutrinos decouple quickly from the primordial plasma and propagate without further interactions. The impact of free-streaming neutrinos is to create a tempo…
The first identification of Lyman Changing-look Quasars at high-redshift in DESI
Wei-Jian Guo, Zhiwei Pan, Małgorzata Siudek +38
We present two cases of Ly changing-look (CL) quasars (J1306 and J1512) along with two additional candidates (J1511 and J1602), all discovered serendipitously at through…
DESIVAST: A Catalog of Low-Redshift Voids using Data from the DESI DR1 Bright Galaxy Survey
Hernan Rincon, Segev BenZvi, Kelly Douglass +37
We present three separate void catalogs created using a volume-limited sample of the DESI Year 1 Bright Galaxy Survey. We use the algorithms VoidFinder and V2 to construct void cat…
DESI Emission Line Galaxies: Unveiling the Diversity of [OII] Profiles and its Links to Star Formation and Morphology
Ting-Wen Lan, J. Xavier Prochaska, John Moustakas +34
We study the [OII] profiles of emission line galaxies (ELGs) from the Early Data Release of the Dark Energy Spectroscopic Instrument (DESI). To this end, we decompose and classify…
Selection of high-redshift Lyman-Break Galaxies from broadband and wide photometric surveys
C. Payerne, W. d'Assignies Doumerg, C. Yèche +44
In this paper, we investigate the possibility of selecting high-redshift Lyman-Break Galaxies (LBG) using current and future broadband wide photometric surveys, such as UNIONS or t…
Stellar reddening map from DESI imaging and spectroscopy
Rongpu Zhou, Julien Guy, Sergey E. Koposov +54
We present new Galactic dust reddening maps of the high Galactic latitude sky using DESI imaging and spectroscopy. We directly measure the reddening of 2.6 million stars by compari…
Detection of the large-scale tidal field with galaxy multiplet alignment in the DESI Y1 spectroscopic survey
Claire Lamman, Daniel Eisenstein, Jaime E. Forero-Romero +36
We explore correlations between the orientations of small galaxy groups, or "multiplets", and the large-scale gravitational tidal field. Using data from the Dark Energy Spectroscop…
DESI Peculiar Velocity Survey -- Fundamental Plane
Khaled Said, Cullan Howlett, Tamara Davis +52
The Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity Survey aims to measure the peculiar velocities of early and late type galaxies within the DESI footprint using bot…
