Distinct Jet Properties in the X-Ray-Obscured State of GRS 1915+105
Xi Yan, Lang Cui, Sergei Trushkin +6
GRS 1915+105 has remained in an X-ray-obscured state since its transition from a long-lasting unobscured state in 2019. We report on 6.7-GHz East Asia VLBI Network observations of…
Discovery of Unusual Jet Orientation Variations in the Microquasar GRS 1915+105
Xi Yan, Lang Cui, Wu Jiang +6
We report large day-timescale variations in the orientation of the southeast--northwest jet in the prototype microquasar GRS 1915+105. These results are based on three-epoch East A…
Accretion Disk Evolution in GX 339-4 Across Spectral States Using NuSTAR, NICER, and Insight-HXMT Observations
Ruchika Dhaka, Ranjeev Misra, Suraj Kumar Chaurasia
We present a broadband spectral analysis of the black hole X-ray binary GX 339-4 during its 2021 outburst, covering both hard and soft spectral states. Using simultaneous observati…
Spectral Analysis of Cyg X-3 using simultaneous AstroSat and Insight-HXMT Observations
Suraj K. Chaurasia, Gitika Mall, Ruchika Dhaka +2
We present the results from the spectral analysis of Cygnus X-3 using simultaneous data from AstroSat and Insight-HXMT during its soft state. A pure reflection spectrum, including…
Discovery of a new flaring class in GRS 1915+105 using AstroSat
Ruchika Dhaka, JS Yadav, Ranjeev Misra +1
Highly variable Black Hole X-ray Binary (BHXB) GRS~1915+105 has shown many flaring classes when the source oscillates between the High Soft state (HS) and the Hard Intermediate sta…
Exploring the broadband spectral and timing characteristics of GRS 1915+105 with AstroSat and NICER observations
Ruchika Dhaka, Ranjeev Misra, JS Yadav +1
In this study, we undertake a spectral-timing analysis of the black hole X-ray binary source GRS 1915+105 using simultaneous observations carried out by AstroSat (LAXPC and SXT) an…
Correlations between QPO frequencies and spectral parameters of GRS 1915+105 using AstroSat observations
Ruchika Dhaka, Ranjeev Misra, JS Yadav +1
In this work, we study the correlation between Quasi-periodic Oscillation (QPO) frequency and the spectral parameters during various X-ray states in the black hole binary GRS 1915+…
