The Kepler Extra-Galactic Survey - Supernovae, Black Holes, and Cosmology

The Kepler Space Telescope’s unique technical capabilities of high precision and high-cadence are not only well suited for finding and studying exoplanets, but also exploding stars. The Kepler Extra Galactic-Survey (KEGS) is a NASA Kepler K2 project which is monitoring thousands of galaxies to search for stellar explosions, active galactic nuclei, and improve measurements of type Ia supernova distances.

A number of projects utilising this data set are available:

  • Organise multi-wavelength follow up of supernovae detected with KEGS and analyze the object including the modeling of the progenitor system.
  • Work on population studies of supernovae discovered with Kepler and put these into the greater context of our existing supernova knowledge.
  • Search through the light-curves to discover new short-lived and faint explosions that have never been discovered before, and lead the analysis of these objects.
  • Use the exquisite light-curves of the type Ia supernovae found in KEGS to improve cosmological distance and dark energy measurements. This will require investigating the relation between their peak brightness and rise-time, and then use this information from Kepler and apply it to existing type Ia supernovae found via traditional ground-based surveys.
