Abstract Type : Poster Abstract Category : Extragalactic astronomy Abstract : We present a detail study of the energetic interaction between the central active galactic nucleus (AGN) and the intra-group medium (IGM) of the galaxy group Abell A3581 and NGC 1407. We made use of currently available Chandra X-ray archival data of group Abell 3581 and NGC 1407, which are known to possess clear pair of X-ray cavities in the inner region. Due to high spatial resolution of the Chandra, 2-d beta model, unsharp masking, surface brightness and temperature profiles techniques, it is possible to detect the cavities in the central region. These cavities are of elliptical shape, exists in pairs. The derived cavity properties like age, power, size and pressure which in turn enable us to understand the mechanism of cavity formation and evolution. Spectroscopic analysis of extended X-ray emission from different regions enable us to examine the variations in derived parameters like X-ray flux, electron density, entropy, metal abundance, temperature and enthalpy. Our result imply that, the cavities are originated due to the AGN outflows associated with the cluster cooling flows. |
