Peering down the barrel with DESI DR2: 10 000+ inflows at < 0.6 reveal how galaxies accrete cold gas
S. Weng, A. Saintonge, M. Pieri +39
Direct observational constraints on how galaxies acquire their gas remain remarkably limited, hindering our understanding of the baryon cycle. We present a search for down-the-barr…
Deep Learning Improves Photometric Redshifts in All Regions of Color Space
Emma R. Moran, Brett H. Andrews, Jeffrey A. Newman +1
Photometric redshifts (photo-'s) are crucial for the cosmology, galaxy evolution, and transient science drivers of next-generation imaging facilities like the Euclid Mission, th…
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…
Stellar reddening map from DESI imaging and spectroscopy
Rongpu Zhou, Julien Guy, Sergey E. Koposov +54
We present new Galactic dust reddening maps of the high Galactic latitude sky using DESI imaging and spectroscopy. We directly measure the reddening of 2.6 million stars by compari…
SDSS-IV MaNGA: galaxy gas-phase metallicity gradients vary across the mass-size plane
Nicholas F. Boardman, Gail Zasowski, Jeffrey A. Newman +5
Gas-phase abundances and abundance gradients provide much information on past stellar generations, and are powerful probes of how galaxies evolve. Gas abundance gradients in galaxi…
