Mangalam (Indian Institute of Astrophysics, Bangalore) Abstract Type : Poster Abstract Category : Extragalactic astronomy Abstract : A supermassive black hole influences the orbital and spatial distribution of stars in the inner parsec region of its host galaxy which together determine the ingestion rate of stars; this results in tidal disruption events (TDEs) where the stars are disrupted by the strong tidal gravity of the hole. By using orbital elements of the star, namely the energy and angular momentum, we make predictions for the physical parameters of the disk that is formed after a TDE. We then self-consistently calculate the time evolution of the relativistic accretion disk and determine the mass and angular momentum feeding rate into the hole; this allows an estimate of the jet power modeled by the Blandford-Znajek process. Using standard cosmological parameters and instrument details, we predict the detectable rates for the various radio surveys and compare our results with observations of radio transients. |
