ODIN: Spectroscopic Validation of Ly-Emitting Galaxy Samples with DESI

Ethan Pinarski, Govind Ramgopal, Nicole Firestone +65

The One-hundred-deg^2 DECam Imaging in Narrowbands (ODIN) survey is conducting the widest-field deep narrow-band imaging of the equatorial and southern skies. ODIN uses three custo…

ODIN: Confirmation and 3D Reconstruction of Six Massive Protoclusters at Cosmic Noon

Ashley Ortiz, Vandana Ramakrishnan, Kyoung-Soo Lee +64

Protoclusters represent sites of accelerated galaxy formation and extreme astrophysical activity characteristic of dense environments. Identifying massive protoclusters and mapping…

ODIN: The LAE Lyα Luminosity Function over Cosmic Time and Environmental Density

Gautam Nagaraj, Robin Ciardullo, Caryl Gronwall +53

The ubiquity and relative ease of discovery make Ly emitting galaxies (LAEs) ideal tracers for cosmology. In addition, because Ly is a resonance line,…

DESI Emission-line Galaxies: Clustering Dependence on Stellar Mass and [OII] Luminosity

T. Hagen, K. S. Dawson, Z. Zheng +49

We measure the projected two-point correlation functions of emission-line galaxies (ELGs) from the Dark Energy Spectroscopic Instrument (DESI) One-Percent Survey and model their de…

Backlighting extended gas halos around luminous red galaxies: kinematic Sunyaev-Zel'dovich effect from DESI Y1 x ACT

Bernardita Ried Guachalla, Emmanuel Schaan, Boryana Hadzhiyska +58

The gas density profile around galaxies, shaped by feedback and affecting the galaxy lensing signal, is imprinted on the cosmic microwave background (CMB) by the kinematic Sunyaev-…

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…

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…

Tracing the evolution of the cool gas in CGM and IGM environments through Mg II absorption from redshift z=0.75 to z=1.65 using DESI-Y1 data

X. Wu, Z. Cai, T. -W. Lan +35

We present a measurement of the mean absorption of cool gas traced by Mg II () around emission line galaxies (ELGs), spanning spatial scales from 20 kpc to 10 Mpc.…

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…

PROVABGS: The Probabilistic Stellar Mass Function of the BGS One-Percent Survey

ChangHoon Hahn, Jessica Nicole Aguilar, Shadab Alam +33

We present the probabilistic stellar mass function (pSMF) of galaxies in the DESI Bright Galaxy Survey (BGS), observed during the One-Percent Survey. The One-Percent Survey was one…

Dark matter halo shapes in the Auriga simulations

Jesus Prada, Jaime E. Forero-Romero, Robert J. J. Grand +2

We present shape measurements of Milky Way-sized dark matter halos at redshift in a suite of 30 zoom simulations from the Auriga project. We compare the results in full magne…
