The Composite Spectrum of QSO Absorption Line Systems in DESI DR2

Lucas Napolitano, Adam D. Myers, Adam Tedeschi +43

We present details regarding a composite spectrum of quasar (QSO) absorption line systems. In this composite spectrum we identify more than 70 absorption lines, and observe oxygen…

The Milky Way stellar halo is twisted and doubly broken: insights from DESI DR2 Milky Way Survey observation

Songting Li, Wenting Wang, Sergey E. Koposov +45

Using K giants from the second data release (DR2) of the Dark Energy Spectroscopic Instrument (DESI) Milky Way (MW) Survey, we measure the shape, orientation, radial profile, and d…

Effect of local environment on Ly line profile in DESI/ODIN LAEs

Ana Sofía M. Uzsoy, Arjun Dey, Anand Raichoor +51

Lyman-Alpha Emitters (LAEs) are star-forming galaxies with significant Ly emission and are often used as tracers of large-scale structure at high redshift. We explore the relati…

Quasars acting as Strong Lenses Found in DESI DR1

Everett McArthur, Martin Millon, Meredith Powell +52

Quasars acting as strong gravitational lenses offer a rare opportunity to probe the redshift evolution of scaling relations between supermassive black holes and their host galaxies…

ODIN: Characterizing the Three-dimensional Structure of Two Protocluster Complexes at

Vandana Ramakrishnan, Ashley Ortiz, Byeongha Moon +52

We present a detailed study of the 3D morphology of two extended associations of multiple protoclusters at . These protocluster 'complexes', designated COSMOS-z3.1-A and COS…

DESI DR2 Galaxy Luminosity Functions

Samuel G. Moore, Shaun Cole, Michael Wilson +54

We present galaxy luminosity functions (LFs) for the Dark Energy Spectroscopic Instrument (DESI) DR2 Bright Galaxy Survey (BGS) in the g,r,z, and w1 bands over 0.002<z<0.6. Our ana…

Dwarf galaxy halo masses from spectroscopic and photometric lensing in DESI and DES

Helena Treiber, Alexandra Amon, Risa H. Wechsler +46

We present the most precise and lowest-mass weak lensing measurements of dwarf galaxies to date, enabled by spectroscopic lenses from the Dark Energy Spectroscopic Instrument (DESI…

The dark matter content of Milky Way dwarf spheroidal galaxies: Draco, Sextans and Ursa Minor

Hao Yang, Wenting Wang, Ling Zhu +50

The Milky Way Survey of the Dark Energy Spectroscopic Instrument (DESI) has so far observed three classical dwarf spheroidal galaxies (dSphs): Draco, Sextans and Ursa Minor. Based…

The Cocytos Stream: A Disrupted Globular Cluster from our Last Major Merger?

Christian Aganze, Vedant Chandra, Risa H. Wechsler +48

The census of stellar streams and dwarf galaxies in the Milky Way provides direct constraints on galaxy formation models and the nature of dark matter. The DESI Milky Way survey --…

Luminosity and stellar mass functions of faint photometric satellites around spectroscopic central galaxies from DESI Year-1 Bright Galaxy Survey

Wenting Wang, Xiaohu Yang, Yipeng Jing +47

We measure the luminosity functions (LFs) and stellar mass functions (SMFs) of photometric satellite galaxies around spectroscopically identified isolated central galaxies (ICGs).…

SpecDis: Value added distance catalogue for 4 million stars from DESI Year-1 data

Songting Li, Wenting Wang, Sergey E. Koposov +55

We present the SpecDis value added stellar distance catalog accompanying DESI DR1. SpecDis trains a feed-forward Neural Network (NN) with Gaia parallaxes and gets the distance esti…

Iron-corrected Single-epoch Black Hole Masses of DESI Quasars at low redshift

Zhiwei Pan, Linhua Jiang, Wei-Jian Guo +31

We present a study on the possible overestimation of single-epoch supermassive black hole (SMBH) masses in previous works, based on more than 55,000 type 1 quasars at $0.25 < z < 0…
