GRBs 070429B and 070714B: The High End of the Short-Duration Gamma-Ray Burst Redshift Distribution
S. Bradley Cenko, Edo Berger, Ehud Nakar +11
We present optical spectra of the host galaxies of the short-duration gamma-ray burst GRB 070429B and the likely short-duration with extended emission GRB 070714B. In both cases, w…
A Survey for Supernovae in Massive High-Redshift Clusters
Keren Sharon, A. Gal-Yam, D. Maoz +12
We describe our ongoing program designed to measure the SN-Ia rate in a sample of massive z=0.5-0.9 galaxy clusters. The SN-Ia rate is a poorly known observable, especially at high…
Determination of stellar shape in microlensing event MOA 2002-BLG-33
N. J. Rattenbury, F. Abe, D. P. Bennett +30
We report a measurement of the shape of the source star in microlensing event MOA 2002-BLG-33. The lens for this event was a close binary whose centre-of-mass passed almost directl…
Constraints on SN Ia Progenitors and ICM enrichment from field and cluster SN rates
Dan Maoz, Avishay Gal-Yam
The iron mass in galaxy clusters is about 6 times larger than could have been produced by core-collapse SNe, assuming the stars in cluster galaxies formed with a standard IMF. Type…
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…
Supernovae in Galaxy Clusters
A. Gal-Yam, D. Maoz, K. Sharon +3
We present the results of several surveys for supernovae (SNe) in galaxy clusters. SNe discovered in deep, archival HST images were used to measure the cluster SN Ia rate to z=1. A…
