Title: Supernovae in Extreme Environments
Abstract:
The Catalina Real-time Transient Survey (CRTS) currently covers
33,000 square degrees of the sky in search of transient astrophysical
events. Data provided by the Catalina Sky Survey provides an unequaled
baseline against which more than 4000 unique optical transient events
have been discovered and openly published in real-time. Of the more
than 800 supernovae discovered among these are distinct classes of
previously undetected extremely luminous type-Ic and type-IIn
supernovae. These events appear to reside predominately in very faint,
low-metalicity, star-forming galaxies. Similar to the environments that
have been associated with so called hypernova explosions. However, the
recent discovery of what was very likely the most luminous and optically
energetic supernova ever discovered, CSS100217, within the AGN disk of a
bright NLS1 galaxy, demonstrates that extreme supernova can occur in a
variety of extreme environments. Here we propose to use Gemini
observations to continue our study of the extreme supernova populations
discovered by CRTS.
