New Ultracool Companions to Nearby White Dwarfs
Alexia Bravo, Adam C. Schneider, Sarah Casewell +15
We conducted a search for new ultracool companions to nearby white dwarfs using multiple methods, including the analysis of colors and examination of images in both the optical and…
ELG Spectroscopic Systematics Analysis of the DESI Data Release 1
Jiaxi Yu, Ashley J. Ross, Antoine Rocher +58
Dark Energy Spectroscopic Instrument (DESI) uses more than 2.4 million Emission Line Galaxies (ELGs) for 3D large-scale structure (LSS) analyses in its Data Release 1 (DR1). Such l…
DESI Massive Post-Starburst Galaxies at have compact structures and dense cores
Yunchong Zhang, David J. Setton, Sedona H. Price +33
Post-starburst galaxies (PSBs) are young quiescent galaxies that have recently experienced a rapid decrease in star formation, allowing us to probe the fast-quenching period of gal…
New Cold Subdwarf Discoveries from Backyard Worlds and a Metallicity Classification System for T Subdwarfs
Adam J. Burgasser, Adam C. Schneider, Aaron M. Meisner +36
We report the results of a spectroscopic survey of candidate T subdwarfs identified by the Backyard Worlds: Planet 9 program. Near-infrared spectra of 31 sources with red co…
The first identification of Lyman Changing-look Quasars at high-redshift in DESI
Wei-Jian Guo, Zhiwei Pan, MaÅgorzata 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…
DESI 2024 VI: Cosmological Constraints from the Measurements of Baryon Acoustic Oscillations
DESI Collaboration, A. G. Adame, J. Aguilar +200
We present cosmological results from the measurement of baryon acoustic oscillations (BAO) in galaxy, quasar and Lyman- forest tracers from the first year of observations from…
