  • 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 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 ...
  • 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 ...
  • Study of accretion flows around an ultraluminous X-ray source M82 X-1 using NuSTAR data 
    Mondal, Santanu; Palit, Biswaraj; Chakrabarti, Sandip K (Indian Academy of Sciences, 2022-12)
    We study the spectral properties and accretion flow behavior of an ultraluminous X-ray source M82 X-1 using NuSTAR observations. We use the physical two-component advective flow (TCAF) model to fit the data and to derive ...
