Optical Spectroscopy of Type Ia Supernovae
T. Matheson, R. P. Kirshner, P. Challis +19
We present 432 low-dispersion optical spectra of 32 Type Ia supernovae (SNe Ia) that also have well-calibrated light curves. The coverage ranges from 6 epochs to 36 epochs of spect…
Strongly Variable z=1.48 FeII and MgII Absorption in the Spectra of z=4.05 GRB 060206
H. Hao, K. Z. Stanek, A. Dobrzycki +9
We report on the discovery of strongly variable FeII and MgII absorption lines seen at z=1.48 in the spectra of the z=4.05 GRB 060206 obtained between 4.13 to 7.63 hours (observer…
"Anomalous" Optical GRB Afterglows are Common: Two z~4 Bursts, GRB 060206 and 060210
K. Z. Stanek, X. Dai, J. L. Prieto +9
We report on two recent z~4 gamma-ray bursts (GRBs), GRB 060206 and GRB 060210, for which we have obtained well-sampled optical light curves. Our data, combined with early optical…
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…
Deep Photometry of GRB 041006 Afterglow: Hypernova Bump at Redshift z=0.716
K. Z. Stanek, P. M. Garnavich, P. A. Nutzman +17
We present deep optical photometry of the afterglow of gamma-ray burst (GRB) 041006 and its associated hypernova obtained over 65 days after detection (55 R-band epochs on 10 diffe…
Photometry and Spectroscopy of GRB 030329 and Its Associated Supernova 2003dh: The First Two Months
T. Matheson, P. M. Garnavich, K. Z. Stanek +4
We present extensive optical and infrared photometry of the afterglow of gamma-ray burst (GRB) 030329 and its associated supernova (SN) 2003dh over the first two months after detec…
