摘要: Using deep Chandra observations of M84, we study the energetics interaction between black hole and interstellar medium this early-type galaxy. We perform a detailed two-dimensional reconstruction properties X-ray-emitting gas using constrained Voronoi tessellation method, identifying mean trends carrying out fluctuation analysis thermodynamical hot ISM. In addition to PV work associated with bubble expansion, identify measure wave energy mildly supersonic expansion. show that, depending on age cavity wave, waves can make substantial contribution total release from AGN. The dissipated in tends be concentrated near center M84 direction perpendicular outflow, possibly due interference generated by expansion northern southern bubbles. also find direct evidence for escape radio plasma ISM host galaxy into intergalactic medium.
