Revisiting the galactic X-ray binary MAXI J1631-479: Implications for high inclination and a massive black hole
Sandeep K. Rout, Santosh Vadawale, Javier Garcia +1
X-ray spectroscopy of galactic black hole binaries serve as a powerful tool to gain an overall understanding of the system. Not only can the properties of the accretion disk be stu…
Optical and X-ray studies of Be/X-ray binary 1A 0535+262 during its 2020 giant outburst
Birendra Chhotaray, Gaurava K. Jaisawal, Neeraj Kumari +3
We report results obtained from the optical and X-ray studies of the Be/X-ray binary 1A 0535+262/HD 245770 during the 2020 October giant X-ray outburst, using the 1.2 m telescope a…
Broadband X-ray Spectroscopy and Estimation of Spin of the Galactic Black Hole Candidate GRS 1758-258
Arghajit Jana, Hsiang-Kuang Chang, Arka Chatterjee +2
We present the results of a broadband (0.5-78 keV) X-ray spectral study of the persistent Galactic black hole X-ray binary GRS 1758-258 observed simultaneously by Swift and NuSTAR.…
Hard X-ray polarization catalog for a 5-year sample of Gamma-Ray Bursts using AstroSat CZT-Imager
Tanmoy Chattopadhyay, Soumya Gupta, Shabnam Iyyani +16
Cadmium Zinc Telluride Imager (CZTI) aboard AstroSat has been regularly detecting Gamma-Ray Bursts (GRBs) since its launch in 2015. Its sensitivity to polarization measurements at…
Evidence of jet induced optical microvariability in radio-loud Narrow Line Seyfert 1 Galaxies
Vineet Ojha, Vivek Kumar Jha, Hum Chand +1
To quantify the role of radio jets for Intra-Night Optical Variability (INOV) in Radio-Loud Narrow-Line Seyfert 1 (RLNLSy1) galaxies, we report the first systematic comparative INO…
Absorption Variability of the Highly Obscured Active Galactic Nucleus NGC 4507
Arghajit Jana, Claudio Ricci, Sachindra Naik +6
We present a detailed study of the highly obscured active galaxy NGC 4507, performed using four Nuclear Spectroscopic Telescope Array (NuSTAR) observations carried out between May…
Broadband Spectro-temporal Study on Blazar TXS 1700+685
Anuvab Banerjee, Prantik Nandi, Raj Prince +2
We attempt to present a multiwavelength variability and correlation study as well as detailed multi-waveband spectral characteristics of the May 2021 -ray flare of the blazar so…
AstroSat Observation of X-ray Dips and State Transition in the Black Hole Candidate MAXI J1803-298
Arghajit Jana, Sachindra Naik, Gaurava K. Jaisawal +3
We present the results obtained from broadband X-ray timing and spectral analysis of black hole candidate MAXI J1803-298 using an AstroSat observation on May 11-12, 2021. Four peri…
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…
