GRB 050408: An Atypical Gamma-Ray Burst as a Probe of an Atypical Galactic Environment

R. J. Foley, D. A. Perley, D. Pooley +14

The bright GRB 050408 was localized by HETE-II near local midnight, enabling an impressive ground-based followup effort as well as space-based followup from Swift. The Swift data f…

Spectroscopic Redshifts for Seven Lens Galaxies

Eran O. Ofek, Dan Maoz, Hans-Walter Rix +2

We report VLT observations of 11 lensed quasars, designed to measure the redshifts of their lens galaxies. We successfully determined the redshifts for seven systems, five of which…

Optical Lightcurve & Cooling Break of GRB 050502A

S. A. Yost, K. Alatalo, E. S. Rykoff +29

We present lightcurves of the afterglow of GRB050502A, including very early data at t-t_{GRB} < 60s. The lightcurve is composed of unfiltered ROTSE-IIIb optical observations from 4…

UBVRI Light Curves of 44 Type Ia Supernovae

Saurabh Jha, Robert P. Kirshner, Peter Challis +2

We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…

The Time Delays of Gravitational Lens HE0435-1223: An Early-Type Galaxy With a Rising Rotation Curve

C. S. Kochanek, N. D. Morgan, E. E. Falco +4

We present Hubble Space Telescope images and 2 years of optical photometry of the quadruple quasar HE0435-1223. The time delays between the intrinsic quasar variations are 14.4+/-0…
