The velocity field of our Milky Way outer stellar halo based on DESI DR2
Songting Li, Wenting Wang, Sergey E. Koposov +53
Using 64,000 halo K giants from Dark Energy Spectroscopic Instrument (DESI) second Data Release (DR2), we decompose the Milky Way (MW) stellar halo between 3 and 160 kpc into metal…
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…
Extremely Metal-Poor Galaxies in DESI DR1: Connections to Galaxies in the Early Universe
Jipeng Sui, Hu Zou, Dirk Scholte +43
Extremely Metal-Poor Galaxies (XMPGs), defined as having metallicities below 10\% of the solar value, are considered possible local analogs to primordial systems and offer a unique…
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…
The Multi-Phase Circumgalactic Medium of DESI Emission-Line Galaxies at z~1.5
Ting-Wen Lan, J. Xavier Prochaska, J. Aguilar +39
We study the multi-phase circumgalactic medium (CGM) of emission line galaxies (ELGs) at , traced by MgII, and CIV, …
