A Shock Model for the the Outburst from the Supermassive Black Hole in M87
Abstract
We present new results from our analysis of the 500 ksec Chandra observation of M87. The observations show a clear shock and extensive filamentary structure which is closely related to the radio emission. We derive the energy, age, and duration of the outburst that produced the 13 kpc radius shock. With a simple model for the main outburst, we can estimate the fraction of energy deposited in M87's atmosphere and the fraction that is carried away by the weak shock. We show that the deposited energy is comparable to that radiated by M87's cooling atmosphere. We discuss the importance of AGN feedback, seen in M87, for the evolution of galaxies.
