High-Redshift Starbursting Dwarf Galaxies Revealed by GRB Afterglows
Hsiao-Wen Chen, Daniel A. Perley, Lindsey K. Pollack +7
We present a study of 15 long-duration gamma-ray burst (GRB) host galaxies at z>2. The GRBs are selected with available early-time afterglow spectra in order to compare interstella…

Galaxy Clusters in the Line of Sight to Background Quasars: I. Survey Design and Incidence of MgII Absorbers at Cluster Redshifts
S. Lopez, L. F. Barrientos, P. Lira +7
We describe the first optical survey of absorption systems associated with galaxy clusters at z= 0.3-0.9. We have cross-correlated SDSS DR3 quasars with high-redshift cluster/group…
