Microlensing variability in time-delay quasars
D. Paraficz, J. Hjorth, I. Burud +2
We have searched for microlensing variability in the light curves of five gravitationally lensed quasars with well-determined time delays: SBS 1520+530, FBQ 0951+2635, RX J0911+055…
Long gamma-ray bursts and core-collapse supernovae have different environments
A. S. Fruchter, A. J. Levan, L. Strolger +30
When massive stars exhaust their fuel they collapse and often produce the extraordinarily bright explosions known as core-collapse supernovae. On occasion, this stellar collapse al…
Evidence for a Supernova Associated with the X-ray Flash 020903
D. Bersier, A. S. Fruchter, L. -G. Strolger +24
We present ground-based and Hubble Space Telescope optical observations of the X-ray flash (XRF) 020903, covering 300 days. The afterglow showed a very rapid rise in the first day,…
Variable polarization in the optical afterglow of GRB 021004
E. Rol, R. A. M. J. Wijers, J. P. U. Fynbo +19
We present polarimetric observations of the afterglow of gamma-ray burst (GRB) 021004, obtained with the Nordic Optical Telescope (NOT) and the Very Large Telescope (VLT) between 8…
A multi-colour study of the dark GRB 000210 host galaxy and its environment
J. Gorosabel, L. Christensen, J. Hjorth +25
We present UBVRIZJsHKs broad band photometry of the host galaxy of the dark gamma-ray burst (GRB) of February 10, 2000. These observations represent the most exhaustive photometry…
Chandra X-ray Observations of the Quadruply Lensed Quasar RX J0911.4+0551
Nicholas D. Morgan, George Chartas, Michael Malm +5
We present results from X-ray observations of the quadruply lensed quasar RX J0911.4+0551 using data obtained with the Advanced CCD Imaging Spectrometer (ACIS) on board the Chandra…
