Rescuing the intracluster medium of NGC 5813 (May 2015b)

Shlomi Hillel (PhD Student), Assaf Sternberg and I argue that the intracluster medium  (ICM) of the cooling flow galaxy group NGC 5813 is more likely to be heated by mixing of post-shock jets’ gas residing in hot bubbles with the ICM, than by shocks or turbulent-heating. Heating by mixing rescues the outer ICM of NGC 5813 from its predestined fate according to cooling flow feedback scenarios that are based on heating by shocks.  See Paper.
