Determining the fraction of compact objects in the Universe using supernova observations

Astrophysics 2009-11-06 v1

Abstract

We investigate the possibility to determine the fraction of compact objects in the Universe by studying gravitational lensing effects on Type Ia supernova observations. Using simulated data sets from one year of operation of the proposed dedicated supernova detection satellite SNAP, we find that it should be possible to determine the fraction of compact objects to an accuracy of < 5 %.
