Constraints on halo energetics from combined Sunyaev-Zel'dovich measurements

Nicholas Battaglia (Princeton University ) - March 28, 2016 at 12:10 pm

Both feedback and non-thermal processes play important roles in the thermodynamic and star-formation properties of the intracluster medium (ICM). Recently, there have been exciting detections of the kinetic Sunyaez-Zel'dovich (SZ) from galaxy clusters. These measurements and future ones provide a new window into the thermodynamic properties of the ICM. I will show how we propose to constrain the average feedback and non-thermal pressure support by combining thermal SZ and kinetic SZ measurements. These constraints will further inform the sub-grid feedback models used in galaxy formation simulations.

The seminar will be held in 131A Campbell Hall.
