Imaging calibration of AstroSat Cadmium Zinc Telluride Imager (CZTI)
Ajay Vibhute, Dipankar Bhattacharya, N. P. S. Mithun +3
AstroSat is India's first space-based astronomical observatory, launched on September 28, 2015. One of the payloads aboard AstroSat is the Cadmium Zinc Telluride Imager (CZTI), ope…
Deep Co-Added Sky from Catalina Sky Survey Images
Akshat Singhal, Varun Bhalerao, Ashish A. Mahabal +12
A number of synoptic sky surveys are underway or being planned. Typically they are done with small telescopes and relatively short exposure times. A search for transient or variabl…
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…
A machine learning approach for GRB detection in AstroSat CZTI data
Sheelu Abraham, Nikhil Mukund, Ajay Vibhute +6
We present a machine learning (ML) based method for automated detection of Gamma-Ray Burst (GRB) candidate events in the range 60 keV - 250 keV from the AstroSat Cadmium Zinc Tellu…
In-orbit performance of AstroSat CZTI
Santosh V. Vadawale, A. R. Rao, Dipankar Bhattacharya +6
Cadmium-Zinc-Telluride Imager (CZTI) is one of the five payloads on-board recently launched Indian astronomy satellite AstroSat. CZTI is primarily designed for simultaneous hard X-…
The Cadmium Zinc Telluride Imager on AstroSat
V. Bhalerao, D. Bhattacharya, A. Vibhute +21
The Cadmium Zinc Telluride Imager (CZTI) is a high energy, wide-field imaging instrument on AstroSat. CZT's namesake Cadmium Zinc Telluride detectors cover an energy range from 20…
