The Crab Nebula is the remnant of a powerful stellar explosion first observed in 1054 AD and is the most studied object outside of our solar system. Our three-pronged research is focused on understanding the emission mechanisms responsible for energy range 100 MeV – 10 TeV. Our project consisted of 1) making light curves of Crab Nebula from Fermi-LAT’s data, 2) extending and investigating the pre-existing VERITAS light curve, and 3) phaseograms of the Crab Pulsar using VERITAS’s data.
