Wise Observatory Optical Transient Search
The Wise Observatory Optical Transients Search (WOOTS) is a program to find
Supernovae (SNe) and other optical transients
in 163 medium-redshift (z between 0.06 and 0.2)
Abell galaxy clusters, using the Wise
Observatory 1m telescope in Israel.
This program has already discovered more than
15 SNe , 11 of them spectroscopically
confirmed with z=0.05 - 0.24. We have also discovered variable
stellar objects (some of which are AGN) and dozens of asteroids.
With our cluster SN sample, we are calculating SN rates in cluster vs.
with implications for cluster star formation and metallicity studies.
Following the discovery of a SN in the remote periphery (78 Kpc) of the cD
galaxy of Abell 403, we also work on a novel explanation for the centrally
enhanced metal abundances indicated by X-ray observations of galaxy clusters.
This search is also sensitive to lensed SNe behind clusters, flares in galactic
nuclei due to tidal disruption of stars by central massive black holes, and
"misdirected" optical counterparts of Gamma-ray bursts.
