Time Series Analysis is an essential tool used in a wide range of fields, for a broad range of purposes. A time series of a particular quantity (say, the market value of a product or daily rainfall of a city) traces the variation of that quantity in time. Nowadays, time series analysis is widely used for forecasting using properly sampled data. The same analysis techniques have been used in astrophysics using the observed intensity variations of distant objects.
In this project, we are going to use fundamental time series analysis tools to search for periodic or quasi periodic signals in the high energy gamma ray data of neutron stars, which are the densest but still visible objects in the Universe. NASA's Fermi Gamma Ray Space Telescope has been observing the whole sky in gamma rays since 2008. We will employ this extensive database of Fermi Large Area Detector to uncover short and long term intensity trends for a set of neutron stars.
