Studying fast gamma-ray variability of bright blazars

Project: 
Blazars, a subclass of active galactic nuclei (AGN) dominate the gamma-ray sky and are known for their extreme variability. For the brightest flares, flux variation times of less then a day are observed. This intra-day variability (IDV) allows us to put strong constrains on the size and location of the gamma-ray emitting region. In this project, we aim to systematically study the flaring behavior of bright blazar flares on different time scales, using more then 10 years of continuous Fermi-LAT gamma-ray observations. The student will perform a Fermi-LAT gamma-ray analysis of a sample of bright blazar flares, in order to search for IDV and compare his/her findings to theoretical predictions. A basic knowledge of gamma-ray astronomy and programming (C++, python) is advantageous, but not mandatory.
