Internship students in the High Energy Astrophysics Lab conducted a timing analysis of the high-mass X-ray binary source using archival data from the XMM-Newton space telescope. The project focused on extracting and processing X-ray data from EPIC instruments, removing background flaring, and generating clean light curves using the Science Analysis System (SAS) and DS9.

Students applied timing analysis techniques using XRONOS, including power-spectrum analysis and light-curve folding, to investigate the periodic behavior of the system. The analysis revealed a stable spin period of approximately 139 seconds, consistent with accretion-powered emission from a magnetized neutron star.
This project introduced students to real space-mission data and standard X-ray astronomy analysis pipelines.
