Fundamental calibration of X-ray CCD onboard Astrosat SXT

Project: 
AstroSat is an Indian space based multi-wavelength observatory, staring at astronomical objects over a wide range in energies, simultaneously. X-ray binaries (XRBs), blazars and GRBs are some of the several main targets which are regularly being monitored by Indian and international community since its launch in September 2015. I have been instrumental in calibration of X-ray imaging instrument onboard AstroSat, named as the Soft X-ray Telescope (SXT). This telescope is equipped with Charge Coupled Device (CCD) as the focal plane detector which is almost identical to the one flown on XMM and Swift XRT. My involvement in calibrations have provided me  a unique opportunity to understand the very basics of astronomy grade optics and detectors in addition to my scientific endeavors. This project will focus on Charge Transfer Inefficiency (CTI) measurements & applications, refinement of the Ancillary Response File (ARF; an important measurement enlisting energy dependent effective area of the instrument) using astronomical observations, and detector background & its applications. The project offered has fascinating goals and the interested student will actively be collaborating with our international collaborators.
