Title: Catching Supernovae in the Act with KEGS (Kepler Extra-Galactic Survey) and DECam

Abstract: The progenitors of type Ia supernovae remain a mystery despite their importance as fundamental distance indicators. We still do not know if type Ia explosions come from single degenerate binary stars or binaries made of two white dwarfs. Recent models show that the secondary star in a single degenerate binary will cause bright shock emission in the first hours or days after the explosion while double degenerate explosions are expected to brighten monotonically. Using Kepler, we plan to monitor about 3000 bright ($m_R < 20$) galaxies at $z < 0.10$ in each of two, K2 Campaign Fields (Field 10 and 12) in order to obtain the early light curves of a few supernovae - not only Ia but also core collapse supernova of which we can constrain the physics of the early explosion. Following up on the success of our Field 5 and 6 DECam observations (two confirmed supernova and 5 candidates confirmed after Kepler data download), we are proposing for time on DECam to monitor the K2 fields, for early ground-based detection of the SN, as Kepler data can be delayed up to 6 months, missing crucial ground-based follow-up.
