Annual Student Research Poster Session

Although the Crab Nebula is well understood, the Very Energetic Radiation Imaging Telescope Array System (VERITAS) still regularly observes the Crab's highest energy emissions. These emissions are used to calibrate the telescopes, further, document the system, and investigate the validity of physical models. Our research this summer is geared to analyze data from 2018-2022 to add to an ongoing research project investigating the long term variability of the Crab Nebula’s emission.

Annual Student Research Poster Session

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.
