Singh (Tata Institute of Fundamental Research, Mumbai-400005), Sunder Sahayanathan (ApSD, Bhabha Atomic Research Centre, Mumbai-400085) Abstract Type : Poster Abstract Category : Extragalactic astronomy Abstract : 3C 454.3 belongs to flat spectrum radio quasar class of blazars – known for their highly variable non-thermal continuum emission across the electromagnetic spectrum from radio to $\gamma$-rays. The nature and origin of high energy emission (X-rays and beyond), however, is remain unclear as both the leptonic and hadronic models being able to reproduce it well. Further, the rapid broadband variability demands simultaneous multi-wavelength coverage and correlation analysis to unravel the same. Being one of the brightest $\gamma$-ray blazars in the GeV sky, 3C 454.3 is been a prime target of multi-wavelength campaigns, aimed at understanding the physical processes responsible for broadband emission. I will present a detailed systematic multi-wavelength spectral and temporal analyses along with spectral modeling of the source and discuss its implications on high energy emission and acceleration processes in the source. |
