The Atacama Cosmology Telescope: A measurement of galaxy cluster temperatures through relativistic corrections to the thermal Sunyaev-Zeldovich effect

Posted by dbos Cambridge

Kavli Affiliate: Blake Sherwin | First 5 Authors: William R. Coulton, Adriaan J. Duivenvoorden, Zachary Atkins, Nicholas Battaglia, Elia Stefano Battistelli | Summary: The high electron temperature in galaxy clusters ($>1,$keV or $>10^7,$K) leads to corrections at the level of a few percent in their thermal Sunyaev-Zeldovich effect signatures. Both the size and frequency dependence […]
