A timing-based estimate of the spin of the black hole in MAXI J1820+070
Yash Bhargava, Tomaso Belloni, Dipankar Bhattacharya +2
MAXI J1820+070 (ASSASN-18ey) is a Black hole X-ray binary discovered in 2018. The brightness of the source triggered multi-wavelength campaigns of this source from different observ…
AstroSat detection of a mHz QPO and cyclotron line in IGR J19294+1816 during the 2019 outburst
Gayathri Raman, Varun, Biswajit Paul +1
We present results from timing and spectral analysis of the HMXB X-ray pulsar IGR J19294+1816 observed using \asr during its recent Type-I outburst in October, 2019. AstroSat obser…
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…
GRB 140102A: Insight into Prompt Spectral Evolution and Early Optical Afterglow Emission
Rahul Gupta, S. R. Oates, S. B. Pandey +38
We present and perform a detailed analysis of multi-wavelength observations of \thisgrb, an optical bright GRB with an observed reverse shock (RS) signature. Observations of this G…
Using collimated CZTI as all sky X-ray detector based on Earth Occultation Technique
Akshat Singhal, Rahul Srinivasan, Varun Bhalerao +3
All-sky monitors can measure the fluxes of astrophysical sources by measuring the changes in observed counts as the source is occulted by the Earth. Such measurements have typicall…
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…
