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…

Bayesian Component Separation for DESI LAE Automated Spectroscopic Redshifts and Photometric Targeting

Ana Sofía M. Uzsoy, Andrew K. Saydjari, Arjun Dey +37

Lyman Alpha Emitters (LAEs) are valuable high-redshift cosmological probes traditionally identified using specialized narrow-band photometric surveys. In ground-based spectroscopy,…
