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…
The atomic gas sequence and mass-metallicity relation from dwarfs to massive galaxies
D. Scholte, A. Saintonge, J. Moustakas +43
Galaxy scaling relations provide insights into the processes that drive galaxy evolution. The extension of these scaling relations into the dwarf galaxy regime is of particular int…
DESI Early Data Release Milky Way Survey Value-Added Catalogue
Sergey E. Koposov, C. Allende-Prieto, A. P. Cooper +40
We present the stellar value-added catalogue based on the Dark Energy Spectroscopic Instrument (DESI) Early Data Release. The catalogue contains radial velocity and stellar paramet…
GD-1 Stellar Stream and Cocoon in the DESI Early Data Release
Monica Valluri, Parker Fagrelius, Sergey. E. Koposov +49
We present 115 new spectroscopically identified members of the GD-1 tidal stream observed with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We confirm the existence…
AuriDESI: Mock Catalogues for the DESI Milky Way Survey
Namitha Kizhuprakkat, Andrew P. Cooper, Alexander H. Riley +31
The Dark Energy Spectroscopic Instrument Milky Way Survey (DESI MWS) will explore the assembly history of the Milky Way by characterising remnants of ancient dwarf galaxy accretion…
Probing the impact of radio-mode feedback on the properties of the cool circumgalactic medium
Yu-Ling Chang, Ting-Wen Lan, J. Xavier Prochaska +33
We explore the influence of radio-mode feedback on the properties of the cool circumgalactic medium (CGM). To this end, we assemble a statistical sample of approximately 30,000 rad…
Identifying Quasars from the DESI Bright Galaxy Survey
S. Juneau, R. Canning, D. M. Alexander +56
The Dark Energy Spectroscopic Instrument (DESI) cosmology survey includes a Bright Galaxy Survey (BGS) which will yield spectra for over ten million bright galaxies (r<20.2 AB mag)…
Emission Line Predictions for Mock Galaxy Catalogues: a New Differentiable and Empirical Mapping from DESI
Ashod Khederlarian, Jeffrey A. Newman, Brett H. Andrews +43
We present a simple, differentiable method for predicting emission line strengths from rest-frame optical continua using an empirically-determined mapping. Extensive work has been…
Measuring the conditional luminosity and stellar mass functions of galaxies by combining the DESI LS DR9, SV3 and Y1 data
Yirong Wang, Xiaohu Yang, Yizhou Gu +42
In this investigation, we leverage the combination of Dark Energy Spectroscopic Instrument Legacy imaging Surveys Data Release 9 (DESI LS DR9), Survey Validation 3 (SV3), and Year…
A Large Sample of Extremely Metal-poor Galaxies at Identified from the DESI Early Data
Hu Zou, Jipeng Sui, Amélie Saintonge +32
Extremely metal-poor galaxies (XMPGs) at relatively low redshift are excellent laboratories for studying galaxy formation and evolution in the early universe. Much effort has been…
The DESI One-Percent Survey: A concise model for galactic conformity of ELGs
Hongyu Gao, Y. P. Jing, Kun Xu +27
Galactic conformity is the phenomenon in which a galaxy of a certain physical property is correlated with its neighbors of the same property, implying a possible causal relationshi…
Changing-look Active Galactic Nuclei from the Dark Energy Spectroscopic Instrument. I.Sample from the Early Data
Wei-Jian Guo, Hu Zou, Victoria Anne Fawcett +34
Changing-look Active Galactic Nuclei (CL AGN) can be generally confirmed by the emergence (turn-on) or disappearance (turn-off) of broad emission lines, associated with a transient…
