Abstract Type : Contributed Talk Abstract Category : Extragalactic astronomy Abstract : Active Galactic Nuclei (AGN) are known to be the manifestation of accretion on to the super-massive black holes (SMBHs) present in the centres of galaxies. Based on the ratio of radio to optical power AGN are divided into two categories named as radio-loud and radio-quiet. In general, radio-loud AGN are found to be hosted in elliptical galaxies with relatively more massive SMBHs (> 10^8 M⊙) and low accretion rates. Contrary to the conventional paradigm we discover several radio-loud AGN hosted in spiral galaxies possessing less massive SMBHs, with high accretion rates. The discovery of these AGN allows to probe the jet production in hitherto unexplored parameter space of the mass of SMBH and accretion rate. In this talk I shall discuss the jet production efficiency in these unconventional AGN. |
