Abstract Type : Poster Abstract Category : Extragalactic astronomy Abstract : We present the result of detection of high energy flare from Mrk-421, using the data of the Large Array Telescope(LAT) on board the Fermi observatory. The analysis is done with 9 month (from October-2009 to June-2010, in the energy range 300 MeV to 100GeV) LAT data of the above Active galactic nucleus (AGN) by using Fermi analysis tools. Flux variability with flux-doubling time of the order of minutes was observed during the most active month February-2010. Two additional flares from the same source are also observed in this campaign during December 2009 and April 2010. The timming parameters of the flares which are associated with several physical quantities like acceleration and deceleration of the blob etc. will also be presented. |
