The CNOC2 sample of intermediate redshift galaxy groups - the powerhouse of galaxy evolution
D. J. Wilman, M. L. Balogh, R. G. Bower +3
The evolution of galaxies in groups may have important implications for the global evolution of star formation rate in the Universe, since many processes which operate in groups ma…
X-ray Spectral Survey with XMM--Newton of a Complete Sample of Nearby Seyfert Galaxies
M. Cappi, F. Panessa, L. Bassani +15
Results obtained from an X-ray spectral survey of nearby Seyfert galaxies using XMM--Newton are reported. The sample was optically selected, well defined, complete in B mag, and di…
Spatially-Resolved Narrow Line Region Kinematics in Active Galactic Nuclei
Melissa S. Rice, Paul Martini, Jenny E. Greene +4
We have analyzed HST spectroscopy of 24 nearby AGNs to investigate spatially-resolved gas kinematics in the Narrow Line Region (NLR). These observations effectively isolate the nuc…
The Progenitors of Short-Hard Gamma-Ray Bursts from an Extended Sample of Events
Avishay Gal-Yam, Ehud Nakar, Eran Ofek +11
The detection of the afterglow emission and host galaxies of short-hard gamma-ray bursts (SHBs) is one of the most exciting recent astronomical discoveries. Indications that SHB pr…
Probing the IGM-Galaxy Connection Toward PKS0405-123 II : A Cross-Correlation Study of Lya Absorbers and Galaxies at z<0.5
Hsiao-Wen Chen, Jason X. Prochaska, Benjamin J. Weiner +2
We present a pilot study of the clustering properties of Lya absorbers with respect to known galaxies based on 112 Lya absorbers and 482 galaxies identified at z<0.5 along the sigh…
The Afterglows, Redshifts, and Properties of Swift Gamma-Ray Bursts
E. Berger, S. R. Kulkarni, D. B. Fox +29
We present optical, near-IR, and radio follow up of sixteen Swift bursts, including our discovery of nine afterglows and a redshift determination for three. These observations, sup…
