Cross-Calibration of Chandrayaan-2 XSM with INSPIRESat-1 DAXSS and GOES-16 XRS
N. P. S. Mithun, Santosh V. Vadawale, Asif M. Mandayapuram +9
X-ray spectroscopic observations of the solar corona and flares provide crucial diagnostics of plasma properties and are essential for understanding the physical processes responsi…
Development of a one-dimensional position sensitive detector for Compton X-ray polarimeters
Abhay Kumar, Santosh V. Vadawale, N. P. S. Mithun +4
The scientific potential of X-ray polarimetry has long been recognized, but the challenges in measuring polarization have left it largely unexplored, particularly in the hard X-ray…
Limits on the axion-photon coupling from Chandrayaan-2 observations
Tanmoy Kumar, N. P. S. Mithun, Subhendra Mohanty +3
Axions and axion-like particles (ALPs) have gained immense attention in searches for beyond Standard Model (BSM) physics. Experiments searching for axions leverage their predicted…
Development of a Compton Imager Setup
Anuraag Arya, Harmanjeet Singh Bilkhu, Sandeep Vishwakarma +16
Hard X-ray photons with energies in the range of hundreds of keV typically undergo Compton scattering when they are incident on a detector. In this process, an incident photon depo…
A Novel Optical Design for Wide-Field Imaging in X-ray Astronomy
Neeraj K. Tiwari, Santosh V. Vadawale, N. P. S. Mithun
Over the decades, astronomical X-ray telescopes have utilized the Wolter type-1 optical design, which provides stigmatic imaging in axial direction but suffers from coma and higher…
