Galaxy Assembly Bias on the Red Sequence
Michael C. Cooper, Anna Gallazzi, Jeffrey A. Newman +1
Using samples drawn from the Sloan Digital Sky Survey, we study the relationship between local galaxy density and the properties of galaxies on the red sequence. After removing the…
AEGIS: The Clustering of X-ray AGN Relative to Galaxies at z~1
Alison L. Coil, Antonis Georgakakis, Jeffrey A. Newman +9
We measure the clustering of non-quasar X-ray AGN at z=0.7-1.4 in the AEGIS field. Using the cross-correlation of 113 Chandra-selected AGN, with a median log L_X=42.8 erg s^-1, wit…
The Large-Scale Environments of Type Ia Supernovae: Evidence for a Metallicity Bias in the Rate or Luminosity of Prompt Ia Events
Michael C. Cooper, Jeffrey A. Newman, Renbin Yan
Using data drawn from the Sloan Digital Sky Survey (SDSS) and the SDSS-II Supernova Survey, we study the local environments of confirmed type Ia supernovae (SNe Ia) in the nearby U…
