"The Evolution of Starburst Galaxies"
Abstract. Massive bursts of star formation represent a transient, and perhaps infrequent phase in the life of massive galaxies, and recent studies are pointing towards a scenario in which the majority of stars in the Universe are formed in a more "quiescent" mode of star formation. However, starbursts triggered by gas-rich mergers at high redshift remain the leading cause for the morphological and spectral disruption required to build the Hubble sequence. I will present recent work attempting to track the observational properties of an evolving sample of starburst galaxies for half a Gyr following the starburst, from the Sloan Digital Sky Survey at low redshift, the Vimos VLT Deep Survey at z~1, and multi wavelength CANDELS survey at z>1. I will show how black hole growth, star formation rate, gas and dust content and morphology evolves following a starburst, and show how we can use these methods to attempt to track the contribution of major gas-rich mergers to the birth and growth of elliptical galaxies.
