Effervescent heating: constraints from nearby cooling flow clusters observed with XMM-Newton
Rocco Piffaretti, Jelle Kaastra
We have used deprojected radial density and temperature profiles of a sample of 16 nearby CF clusters observed with XMM-Newton to test whether the effervescent heating model can sa…
