SUMMARY:Herschel Observations of Dust\, Star Formation and Dark Matter fro
 m z=0 to z=5 - Steve Eales (School of Physics and Astronomy\, University o
 f Cardiff)

CONTACT:David Titterington
DESCRIPTION:I will start by discussing the Herschel observations of M31\, 
 the other big spiral in the Local Group.  I will present evidence that the
  dust in the bulge of M31 is heated from a different source than the dust 
 in the disk\, and show the first evidence for variation within a galaxy in
  the physical properties of dust.  Heading outwards into the Universe\, I 
 will show results from the Herschel Reference Survey\, the first survey of
  dust in a statistically-complete sample of galaxies.  I will use some res
 ults from that survey to test a method for estimating the mass of the inte
 rstellar medium in tens of thousands of galaxies.  I will then present res
 ults from the Herschel ATLAS\, the largest Herschel open-time project.  I 
 will discuss what this survey can tell us about whether nature of nurture 
 is most important for galaxy evolution.  I will describe a new programme\,
  based on the Herschel ATLAS results\, for studying dark-matter halos and 
 estimating cosmological parameters.\n
