Correlations between X-ray spectral parameters of Mkn 421 using long-term Swift-XRT data
Rukaiya Khatoon, Zahir Shah, Jyotishree Hota +3
We have performed a detailed analysis of the X-ray spectra of the blazar Mkn 421 using Swift-XRT observations taken between 2005 and 2020, to quantify the correlations between spec…
AstroSat observation of rapid Type-I thermonuclear burst from the low mass X-ray binary GX 3+1
Ankur Nath, Biplob Sarkar, Jayashree Roy +1
We report the results of an observation of low mass X-ray binary GX 3+1 with {\it AstroSat}'s Large Area X-ray Proportional Counter (LAXPC) and Soft X-ray Telescope (SXT) instrumen…
On the energy dependence of the QPO phenomenon in the black hole system MAXI J1535-571
Akash Garg, Ranjeev Misra, Somasri Sen
Previous analysis of AstroSat observations of the black hole system MAXI J1535-571, have revealed the presence of a strong Quasi-Periodic Oscillation (QPO) whose frequency is corre…
Probing the shot behaviour in Cygnus X-1 using simultaneous AstroSat-NICER observation
Yash Bhargava, Nandini Hazra, A. R. Rao +4
We analyse the aperiodic flaring features, also known as shots, observed in Cyg X-1 in the 0.1-80 keV energy band using a 6.39 ks simultaneous observation with AstroSat and NICER.…
Spectral properties of soft X-ray transient MAXI J0637430 using AstroSat
Neal Titus Thomas, Shivappa B. Gudennavar, Ranjeev Misra +1
Soft X-ray transients are systems that are detected when they go into an outburst, wherein their X-ray luminosity increases several orders of magnitude. These outbursts are markers…
AstroSat Detection of a Quasi-periodic Oscillation at ~ 42 Hz in Cygnus X-2
Vanzarmawii Chhangte, Jayashree Roy, Ranjeev Misra +1
We report the results of AstroSat observations of Cygnus X-2 during February 2016. The source's power density spectrum generated using LAXPC data revealed the presence of a promine…
