  We study the nature of the changing-look active galactic nucleus NGC 1566 during its 2018 June outburst. During the outburst, the X-ray intensity of the source rises up to ?25-30 times compared to its quiescent state ...
• Complex optical/UV and X-ray variability in Seyfert 1 galaxy Mrk 509 

  Kumari, Neeraj; Pal, Main; Naik, Sachindra; Jana, Arghajit; Jaisawal, Gaurava K.; Kushwaha, Pankaj (Cambridge University Press, 2021-09)

  We performed a detailed spectral and timing analysis of a Seyfert 1 galaxy Mrk 509 using data from the Neil Gehrels Swift observatory that spanned over 13 years between 2006 and 2019. To study the variability properties ...
• Heavy quark transport coefficients in a viscous QCD medium with collisional and radiative processes

  The heavy quark drag and momentum diffusion coefficients in the presence of both the collisional and radiative processes have been studied in a hot viscous QCD medium. The thermal medium effects are incorporated by employing ...
• Heavy quark transport in an anisotropic hot QCD medium: collisional and radiative processes 

  Prakash, Jai; Kurian, Manu; Das, Santosh K.; Chandra, Vinod (American Physical Society, 2021-05)

  The impact of momentum anisotropy on the heavy quark transport coefficients due to collisional and radiative processes in the QCD medium has been studied within the ambit of kinetic theory. Anisotropic aspects (momentum) ...
• Islands and complexity of eternal black hole and radiation subsystems for a doubly holographic model 

  Bhattacharya, Aranya; Bhattacharyya, Arpan; Nandy, Pratik; Patra, Ayan K. (Springer Nature, 2021-05)

  We study the entanglement islands and subsystem volume complexity corresponding to the left/ right entanglement of a conformal defect in d-dimensions in Randall-Sundrum (RS) braneworld model with subcritical tension brane. ...
