Numerous Old Starburst Galaxies in the Local Universe

Astrophysics 2009-10-31 v1

Abstract

Old starburst galaxies are deficient in O stars, and hence do not exhibit strong line emission in the optical regime. However, there remain many B stars, which are expected to heat dust grains and generate strong continuum emission in the far-infrared. The IRAS data for a statistically complete sample of nearby galaxies reveal for the first time that such objects are as numerous as 30-40% of the local galaxy population.
