Abstract Type : Poster Abstract Category : Extragalactic Astronomy Abstract : Multi-wavelength variability characteristics of Fermi blazars . Blazars a sub-class of active galactic nuclei are often very luminous and show violent flux variations over the entire electromagnetic spectrum from low radio to high energy gamma-rays . The near continuous monitoring capability of the Large Area Telescope (LAT) instrument on board the Fermi Gamma-Ray Space Telescope has provided the opportunity to study the high energy flux variations . Such variations when coupled with the flux variations at other wavelengths will give the unique opportunity to probe the physical processes happening close to the central regions of blazars . Towards this we have carried out a systematic analysis of the multi-wavelength flux characteristics of 37 blazars using data that spans over 10 years in the optical BVR and the infrared JK bands . Our analysis includes characterizing flux variability at various wavelengths, including gamma-rays, spectral variations, and time delay between flux variations in different wavebands. Details of this work will be presented . |
