The Supernovae Associated with Gamma-Ray Bursts
Thomas Matheson
Supernovae (SNe) were long suspected as possible progenitors of gamma-ray bursts (GRBs). The arguments relied on circumstantial evidence. Several recent GRBs, notably GRB 030329, h…
Optical, Ultraviolet, and Infrared Observations of SN 1993J
Alexei V. Filippenko, Thomas Matheson
We review the existing set of optical/UV/IR observations of Supernova 1993J, concentrating heavily on optical data because these are by far the most plentiful. Some results from th…
The First Direct Supernova/GRB Connection: GRB 030329/SN 2003dh
Thomas Matheson
Observations of gamma-ray burst (GRB) afterglows have yielded tantalizing hints that supernovae (SNe) and GRBs are related. The case had been circumstantial, though, relying on irr…
SN 1994W: evidence of explosive mass ejection a few years before explosion
Nikolai N. Chugai, Robert J. Cumming, Sergei I. Blinnikov +7
We present and analyse spectra of the Type IIn supernova 1994W obtained between 18 and 202 days after explosion. During the first 100 days the line profiles are composed of three m…
Using Multi-Band Photometry to Classify Supernovae
Dovi Poznanski, Avishay Gal-Yam, Dan Maoz +3
Large numbers of supernovae (SNe) have been discovered in recent years, and many more will be found in the near future. Once discovered, further study of a SN and its possible use…
Observation of Cosmological Time Dilation using Type Ia Supernovae as Clocks
G. Goldhaber, S. Deustua, S. Gabi +23
This work is based on the first results from a systematic search for high redshift Type Ia supernovae. Using filters in the R-band we discovered seven such SNe, with redshift z = 0…
