Accretion Disc/corona and jet emission from radio-loud narrow-line Seyfert 1 galaxy
 
 

The existence of fundamental plane of black hole activity suggests a tight correlation between jet power, accretion disc power and black hole mass. Therefore physical processes governing the disc-accretion and jet launching mechanism are universal across mass scales. Although there is a phenomenological understanding of the disc-jet paradigm in black-hole X-ray binaries, the disc-jet connection is not well established for Active Galactic Nuclei. Many efforts have been paid off to understand the radiative processes in the large scale radio jet, however, the role of the innermost disc/corona region for the ejection of jets has been explored in a handful of radio-loud narrow-line Seyfert 1 (RLNLS1) galaxies. In this talk, the speaker will discuss the spectral and temporal properties of RLNLS1 galaxy, RXJ1633.3+4719 focusing on the origin of different spectral components - accretion disc/corona and jet. The speaker will also describe a powerful approach to study the energy dependent variability of AGN and X-ray binaries.
