Herschel-ATLAS: Rapid evolution of dust in galaxies in the last 5 billion years

Understand

We present the first direct and unbiased measurement of the evolution of the dust mass function of galaxies over the past 5 billion years of cosmic history using data from the Science Demonstration Phase of the Herschel-ATLAS.

• The sample consists of galaxies selected at 250{\mu}m which have reliable counterparts from SDSS at z < 0.5, and contains 1867 sources.
• Dust masses are calculated using both a single temperature grey-body model for the spectral energy distribution and also using a model with multiple temperature components.
• The dust temperature for either model shows no trend with redshift.
