K+a galaxies in the zCOSMOS Survey: Physical properties of systems in their post-starburst phase

Understand

The identities of the main processes triggering and quenching star-formation in galaxies remain unclear.

• A key stage in evolution, however, appears to be represented by post-starburst galaxies.
• To investigate their impact on galaxy evolution, we initiated a multiwavelength study of galaxies with k+a spectral features in the COSMOS field.
• We examine a mass-selected sample of k+a galaxies at z=0.48-1.2 using the spectroscopic zCOSMOS sample.
