  • Accretion flow properties of GRS 1716-249 during its 2016–17 failed outburst 
    Chatterjee, Kaushik; Debnath, Dipak; Chatterjee, Debjit; Jana, Arghajit; Sujoy Kumar Nath; Bhowmick, Riya; Chakrabarti, S. K (Springer Nature, 2021-07)
    In 2016–17, the Galactic transient black hole candidate GRS 1716-249 exhibited an outburst event after a long quiescence period of almost 23 years. The source remained in the outbursting phase for almost 9 months. We study ...
  • 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 ...
  • Accretion flow properties of MAXI J1910-057/Swift J1910.2–0546 during its 2012–13 outburst 
    Nath, Sujoy Kumar; Debnath, Dipak; Chatterjee, Kaushik; Jana, Arghajit; Chatterjee, Debjit; Bhowmick, Riya (Elsevier B.V, 2023-01-01)
    Galactic black hole candidate MAXI J1910-057/Swift J1910.2–0546 was simultaneously discovered by MAXI/GSC and Swift/BAT satellites during its first outburst in 2012. We study the detailed spectral and temporal properties ...
  • Accretion properties of MAXI J1813-095 during its failed outburst in 2018 
    Jana, Arghajit; Jaisawal, G. K; Naik, Sachindra; Neeraj Kumari; Chatterjee, Debjit; Chatterje, Kaushik; Bhowmick, Riya; Chakrabarti, S. K; Chang, H.-K; Debnath, Dipak (IOP Publishing, 2021-05)
    We present the results obtained from detailed timing and spectral studies of a black hole candidate MAXI J1813–095 using Swift, NICER, and NuSTAR observations during its 2018 outburst. The timing behavior of the source is ...
  • Anomalous nature of outbursts of black hole candidate 4U 1630-472 
    Chatterjee, Kaushik; Debnath, Dipak; Bhowmick, Riya; Nath, Sujoy Kumar; Chatterjee, Debjit (Oxford University Press on behalf of Royal Astronomical Society, 2022-02)
    The Galactic black hole candidate (BHC) 4U 1630−472 has gone through several outbursts (13 to be particular) in the last two and a half decades starting from the RXTE era till date. Like the outbursts of other transient ...
  • AstroSat observation of non-resonant type-C QPOs in MAXI J1535-571 
    Chatterjee, Debjit; Debnath, D; Jana, A; Shang, J.-R.; Chakrabarti, S.K.; Chang, H.-K; Banerjee, A; Bhattacharjee, A; Chatterjee, K; Bhowmick, R; Nath, S.K (Springer, 2021-08)
    Galactic transient black hole candidate (BHC) MAXI J1535-571 was discovered on 2017 September 02 simultaneously by MAXI/GSC and Swift/BAT instruments. It has also been observed by India’s first multi-wavelength astronomy-mission ...
  • Evolution of low-frequency quasi-periodic oscillations in GX 339-4 during its 2021 outburst using AstroSat data 
    Mondal, Santanu; Salgundi, Anirudh; Chatterjee, Debjit; Jana, Arghajit; Chang, H. K; Naik, Sachindra (Oxford University Press on behalf of Royal Astronomical Society, 2023-12)
    The black hole X-ray binary GX 339-4 showed an X-ray outburst during 2021. The AstroSat captured this outburst when the source entered into the intermediate flux state while the count rate was declining. The source showed ...
  • Jet properties of XTE J1752−223 during its 2009–2010 outburst 
    Debnath, Dipak; Chatterjee, Kaushik; Chatterjee, Debjit; Jana, Arghajit; Chakrabarti, S. K (Oxford University Press on behalf of the Royal Astronomical Society, 2021-07)
    Galactic short orbital period black hole candidate (BHC) XTE J1752−223 was discovered on 2009 October 21 by the Rossi X-ray Timing Explorer (RXTE). We study the spectral properties of this outburst using transonic flow ...
  • NuSTAR and Swift observations of the extragalactic black hole X-ray binaries 
    Jana, Arghajit; Naik, Sachindra; Chatterjee, Debjit; Jaisawal, Gaurava K. (Oxford University Press on behalf of Royal Astronomical Society, 2021-11)
    We present the results obtained from detailed spectral and timing studies of extragalactic black hole X-ray binaries LMC X–1 and LMC X–3, using simultaneous observations with Nuclear Spectroscopic Telescope Array (NuSTAR) ...
  • 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, ...
  • Spectral properties of GX 339−4 in the intermediate state using AstroSat observation 
    Jana, Arghajit; Chatterjee, Debjit; Chang, Hsiang-Kuang; Naik, Sachindra; Monda, Santanu (Oxford University Press on behalf of Royal Astronomical Society, 2024-01)
    We present the results obtained from the spectral studies of black hole X-ray binary GX 339−4 using AstroSat observations during its 2021 outburst. AstroSat observed the source in the intermediate state for ∼600 ks. The ...
