Science with CMB spectral distortions: a new window to the early Universe

Jens Chluba

June 13, 2013



Abstract: Since COBE/FIRAS we know that the CMB spectrum is extremely close to a perfect blackbody. There are, however, a number of processes in the early Universe that should create spectral distortions at a level that is within reach of present day technology. I will give an overview of recent developments, explaining why future measurements of the CMB spectrum could open up an unexplored window to early universe and particle physics.
