Probing into emission mechanisms of GRB 190530A using time-resolved spectra and polarization studies: Synchrotron Origin?
Rahul Gupta, S. Gupta, T. Chattopadhyay +47
Multi-pulsed GRB 190530A, detected by the GBM and LAT onboard \fermi, is the sixth most fluent GBM burst detected so far. This paper presents the timing, spectral, and polarimetric…
The AstroSat Mass Model: Imaging and Flux studies of off-axis sources with CZTI
Sujay Mate, Tanmoy Chattopadhyay, Varun Bhalerao +11
The Cadmium Zinc Telluride Imager (CZTI) on AstroSat is a hard X-ray coded-aperture mask instrument with a primary field of view of 4.6 x 4.6 degrees (FWHM). The instrument collima…
Sub-MeV spectroscopy with AstroSat-CZT Imager for Gamma Ray Bursts
Tanmoy Chattopadhyay, Soumya Gupta, Vidushi Sharma +10
Cadmium Zinc Telluride Imager (CZTI) onboard AstroSat has been a prolific Gamma-Ray Burst (GRB) monitor. While the 2-pixel Compton scattered events (100 - 300 keV) are used to extr…
Exploring Sub-MeV Sensitivity of AstroSat-CZTI for ON-axis Bright Sources
Abhay Kumar, Tanmoy Chattopadhyay, Santosh V Vadawale +5
The Cadmium Zinc Telluride Imager (CZTI) onboard AstroSat is designed for hard X-ray imaging and spectroscopy in the energy range of 20 - 100 keV. The CZT detectors are of 5 mm thi…
Tiny-box: A tool for the versatile development and characterization of low noise fast X-ray imaging detectors
Tanmoy Chattopadhyay, Sven Herrmann, Steven Allen +8
X-ray Charge Coupled Devices (CCDs) have been the workhorse for soft X-ray astronomical instruments for the past quarter century. They provide broad energy response, extremely low…
Identifying charged particle background events in X-ray imaging detectors with novel machine learning algorithms
D. R. Wilkins, S. W. Allen, E. D. Miller +8
Space-based X-ray detectors are subject to significant fluxes of charged particles in orbit, notably energetic cosmic ray protons, contributing a significant background. We develop…
