Description |
In this talk I will explain the heating and cooling mechanism in cool-core cluster
galaxies. Active Galactic Nuclei (AGN) in the center of galaxies group and clusters are
believed to play an important role in galaxy formation and cluster evolution, by regulating
the cooling of the hot gas between them. The current generation X-ray telescopes, like
Chandra and XMM-Newton have revealed a complex relation between heating and cooling,
via spectroscopically measurement of gas cooling and imaging of the interaction of jets
and gas in the core of the clusters. However, the physics of the balance between heating
and cooling process is known for only few nearest systems and so remains poorly
understood. Apart from this I will briefly explain the CZTI calibration part as well as my
future plan.
