1302.6722 (Silvia Posacki et al.)

The effects of flattening and rotation on the temperature of the X-ray halos of elliptical galaxies    [PDF]

Silvia Posacki, Silvia Pellegrini, Luca Ciotti
Elliptical galaxies have hot coronae with X-ray luminosities and mean gas temperatures that span over wide ranges. This variation can be partially due to the energy budget of the hot gas, that depends on the host galaxy structure and internal kinematics. With the aid of realistic axisymmetric galaxy models, we performed a diagnostic study focussed on the effects of galaxy flattening and rotational support on the hot gas temperature.
