Abstract Type : Poster Abstract Category : Extragalactic astronomy Abstract : The Blazar is a type of an active galactic nucleus (AGN) whose relativistic jet oriented along our line of sight. They are highly energetic in nature, emitting in all bands of electromagnetic spectrum. Blazars are rare objects in the universe as they emits in GeV and TeV range (Gamma ray band), which makes their study important. Hence we are studying blazars in high energy band. In this work we present detailed analysis of Fermi Blazar PKS 1424-41 between June, 2012 to August, 2014. For this purpose we used the data of Fermi Large Area Telescope (LAT). Variability and Spectral Energy Distribution (SED) are important tools to study mechanism of physical processes responsible emission from Blazars. Hence we studied the lightcurves and SEDs for individual flares. Blazar PKS 1424-41 exhibit five major gamma ray flares of different flux value along with number of subflares in it. All five flares peaked almost in equal interval from each other. We also studied two small flares and quiescent period of PKS 1424-41. The nature of flares is complex with many showing sharp rise and slow decrease. Here we are using leptonic model to represent SEDs which includes inverse Compton emission. Detailed study of Blazar PKS 1424-41 will be helping us to understand the insights of this class of AGNs. |
