Exploring a Cosmic-Ray Inverse-Compton Origin to the SZ-to-X-Ray Pressure Deficit in the Cool Core Cluster ZwCl 3146
The study investigated if GeV cosmic rays from a central AGN can cause a pressure deficit between Sunyaev-Zel'dovich (SZ) measurements and X-ray measurements in ZwCl 3146. They found a significant deficit, consistent with non-thermal emission from cosmic ray inverse Compton (CR–IC) scattering, suggesting this could mimic thermal emission and help solve the cooling flow problem.
