Emergence of a Quasar Outflow
F. Hamann, K. F. Kaplan, P. Rodriguez Hidalgo +2
We report the first discovery of the emergence of a high-velocity broad-line outflow in a luminous quasar, J105400.40+034801.2 at redshift z ~ 2.1. The outflow is evident in ultrav…
The Orbital Distribution of Satellite Galaxies
Stéphane Herbert-Fort, Dennis Zaritsky, Yeun Jin Kim +2
We measure the distribution of velocities for prograde and retrograde satellite galaxies using a combination of published data and new observations for 78 satellites of 63 extremel…
A photometric search for transients in galaxy clusters
D. J. Sand, D. Zaritsky, S. Herbert-Fort +2
We have begun a program to search for supernovae and other transients in the fields of galaxy clusters with the 2.3m Bok Telescope on Kitt Peak. We present our automated photometri…
The SDSS-DR5 Survey for Proximate Damped Lya Systems
Jason X. Prochaska, Joseph F. Hennawi, Stephane Herbert-Fort
Using the Sloan Digital Sky Survey, Data Release 5, we survey proximate damped Lya systems (PDLAs): absorption line systems with HI column density N(HI)> 2x10^20 cm^{-2} at velocit…
The Metal-Strong Damped Lyman-alpha Systems
Stéphane Herbert-Fort, Jason X. Prochaska, Miroslava Dessauges-Zavadsky +4
We have identified a metal-strong (logN(Zn+) > 13.15 or logN(Si+) > 15.95) DLA (MSDLA) population from an automated quasar (QSO) absorber search in the Sloan Digital Sky Survey Dat…
Super-Solar Super Lyman Limit Systems
Jason X. Prochaska, John M. O'Meara, Stephane Herbert-Fort +3
We present abundance measurements for two super Lyman Limit systems (SLLS; quasar absorption line systems with 10^19 cm^-2 < N_HI < 10^20.3 cm^-2) selected from a set of metal-stro…
