Observational Evidence for Enhanced Black Hole Accretion in Giant Elliptical Galaxies
Michael McDonald, Brian R. McNamara, Michael S. Calzadilla +5
We present a study of the relationship between black hole accretion rate (BHAR) and star formation rate (SFR) in a sample of giant elliptical galaxies. These galaxies, which live a…
Preliminary Target Selection for the DESI Bright Galaxy Survey (BGS)
Omar Ruiz-Macias, Pauline Zarrouk, Shaun Cole +28
The Dark Energy Spectroscopic Instrument (DESI) will execute a nearly magnitude-limited survey of low redshift galaxies (, median ). Clustering…
Reconciling EHT and Gas Dynamics Measurements in M87: Is the Jet Misaligned at Parsec Scales?
Britton Jeter, Avery E. Broderick
The Event Horizon Telescope mass estimate for M87* is consistent with the stellar dynamics mass estimate, and inconsistent with the gas dynamics mass estimates by up to . We ha…
A homogeneous measurement of the delay between the onsets of gas stripping and star formation quenching in satellite galaxies of groups and clusters
Kyle A. Oman, Yannick M. Bahé, Julia Healy +3
We combine orbital information from N-body simulations with an analytic model for star formation quenching and SDSS observations to infer the differential effect of the group/clust…
Probing galaxy evolution in massive clusters using ACT and DES: splashback as a cosmic clock
Susmita Adhikari, Tae-hyeon Shin, Bhuvnesh Jain +113
We measure the projected number density profiles of galaxies and the splashback feature in clusters selected by the Sunyaev--Zeldovich (SZ) effect from the Advanced Atacama Cosmolo…
The Sloan Digital Sky Survey Quasar Catalog: Sixteenth Data Release
Brad W. Lyke, Alexandra N. Higley, J. N. McLane +34
We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog compris…
