  M87 is a key object whose study can reveal the complex phenomena in cooling
cores. We use a deep XMM-Newton observation of M87 to produce detailed
temperature, pressure and entropy maps in order to analyze the physical
processes of cooling cores and of their heating mechanisms. We employed both
broad-band fitting and full spectroscopical one-temperature model analysis to
derive temperature and surface brightness maps, from which the
pseudo-deprojected entropy and pressure were calculated. We discuss possible
physical interpretations of small deviations from radial and elliptical
symmetry in these maps. The most prominent features observed are the E and SW
X-ray arms that coincide with powerful radio lobes, a weak shock at a radius of
3', an overall ellipticity in the pressure map and a NW/SE asymmetry in the
entropy map which we associate with the motion of the galaxy towards the NW.
For the first time we find evidence that cold, metal-rich gas is being
transported out of the center, possibly through bubble-induced mixing. Several
edges in the abundance map indicate an oscillation of the galaxy along the
NW/SE direction. Furthermore, the radio lobes appear to rise along the short
axis of the elliptical pressure distribution, following the steepest gradient
of the gravitational potential, and seem to contain a nonthermal pressure
component.
