Multi-wavelength study of footprints of AGN feedback in host galaxies in the local universe

The supermassive black hole scaling relationships imply there exist feedback mechanisms between

the accreting central supermassive black holes and their host galaxies. We have carried out a multi-

wavelength investigation of these footprints in a sample of nearby active galaxies at z<0 (Siding

Spring Southern Seyfert Spectroscopic Snap-Shot Survey (S7)). We have published the optical IFU

measurements of about 130 AGNs in our sample. The radio observations are ongoing using the

Giant Metre-Wave Radio Telescope, Pune and the Australia Telescope Compact Array, Australia,

with X-ray follow-up using archival XMM and Chandra data. We have studied many galaxies in our

sample individually. One of our targets–Carafe galaxy, a merging system, has been observed with

AstroSat’s SXT, LAXPC and UVIT along with coordinated, same-epoch observations with the

Chandra X-ray telescope. We present our analysis of the Carafe galaxy, which concurs with our

hypothesis that this is a two AGN system.
