  • Accretion flow properties of GRS 1915+105 during Its θ class using AstroSat data 
    Banerjee, Anuvab; Bhattacharjee, Ayan; Chatterjee, Debjit; Debnath, Dipak; Chakrabarti, S. K; Katoch, Tilak; Antia, H. M (IOP Publishing, 2021-08-01)
    The Galactic microquasar GRS 1915+105 shows rich variability that is categorized into different classes. In this paper, we report the temporal and spectral analysis of GRS 1915+105 to study the properties of the accretion ...
  • Decoding the X-Ray Flare from MAXI J0709–159 Using Optical Spectroscopy and Multiepoch Photometry 
    Bhattacharyya, Suman; Mathew, Blesson; Ezhikode, Savithri H; Muneer, S; Selvakumar, G; Maheswar, G; Arun, R; Anilkumar, Hema; Banerjee, Gourav; Kumar, S. P; Kartha, Sreeja S; Paul, KT; Velu, C (IOP Publishing, 2022-07-10)
    We present a follow-up study on the recent detection of two X-ray flaring events by MAXI/Gas Slit Camera observations in soft and hard X-rays from MAXI J0709–159 in the direction of HD 54786 (LY CMa), on 2022 January 25. ...
  • A Geometric Origin for Quasi-periodic Oscillations in Black Hole X-Ray Binaries 
    Prerna Rana; Mangalam, A (IOP Publishing, 2020-11-10)
    We expand the relativistic precession model to include nonequatorial and eccentric trajectories and apply it to quasi-periodic oscillations (QPOs) in black hole X-ray binaries (BHXRBs) and associate their frequencies with ...
  • Relation between Quiescence and Outbursting Properties of GX 339-4 
    Bhowmic, Riya; Debnath, Dipak; Chatterjee, Kaushik; Nagarkoti, Shreeram; Chakrabarti, S. K; Sarkar, Ritabrata; Chatterjee, Debjit; Jana, Arghajit (IOP Publishing, 2021-04-01)
    Galactic black hole candidate GX 339-4 underwent several outbursting phases in the past two and a half decades at irregular intervals of 2–3 years. The nature of these outbursts in terms of the duration, number of peaks, ...
