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.
