Show affiliationsWe analyzed a deep Chandra observation of M84, a bright elliptical galaxy in the core of the Virgo Cluster. We find that the spatial distribution of the soft X-ray emission is defined by the radio structure of the galaxy. In particular, we find two low-density regions associated with the radio lobes and surrounded by higher density X-ray filaments. In addition to a central active galactic nucleus (AGN) and a population of galactic sources, we find a diffuse hard source filling the central 10 kpc region. Since the morphology of the hard source appears round and is different from that seen in the radio or in soft X-rays, we propose that it is hot gas heated by the central AGN. Finally, we find that the central elemental abundance in the X-ray gas is comparable to that measured optically.
