    We present a detailed study of the highly obscured active galaxy NGC 4507, performed using four Nuclear Spectroscopic Telescope Array (NuSTAR) observations carried out between May and August in 2015 (?130 ks in total). ...
  • Jana, Arghajit; Jaisawal, Gaurava K.; Naik, Sachindra; Kumari, Neeraj; Chatterjee, Debjit; Chatterjee, Kaushik; Bhowmick, Riya; Chakrabarti, Sandip K.; Chang, Hsiang-Kuang; Debnath, Dipak (IOP Publishing, 2021-06)
    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 ...
  • Jana, Arghajit; Naik, Sachindra; Jaisawal, Gaurava K.; Chhotaray, Birendra; Kumari, Neeraj; Gupta, Shivangi (Oxford University Press, 2022-04)
    We present the results obtained from broad-band X-ray timing and spectral analysis of black hole (BH) candidate MAXI J1803–298 using an AstroSat observation on 2021 May 11-12. Four periodic absorption dips with a periodicity ...
  • Jaisawal, Gaurava K.; Naik, Sachindra; Epili, Prahlad R.; Chhotaray, Birendra; Jana, Arghajit; Agrawal, P. C (Scientific Research Publishing, 02-10-21)
    We present the results obtained from analysis of two AstroSat observations of the high mass X-ray binary pulsar OAO 1657-415. The observations covered 0.681–0.818 and 0.808–0.968 phases of the ∼10.4 day orbital period of ...
  • Jana, Arghajit; Kumari, Neeraj; Nandi, Prantik; Naik, Sachindra; Chatterjeee, Arka; Jaisawal, Gaurava K.; Hayasaki, Kimitake; Ricci, Claudio (Oxford University Press, 2021-08)
    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 ...
  • 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 ...
  • Jana, Arghajit; Naik, Sachindra; Kumari, Neeraj (Springer, 2022-05)
    We present the results obtained from timing and spectral studies of the highly obscured low luminosity active galactic nucleus NGC 4941 using data obtained from the nuclear spectroscopic telescope array and the Neil Gehrels ...
  • Jana, Arghajit; Jaisawal, Gaurava K.; Naik, Sachindra; Kumari, Neeraj; Chhotaray, Birendra; Altamirano, D.; Remillard, R. A.; Gendreau, Keith C. (Royal Astronomical Society, 2021-07)
    We present detailed timing and spectral studies of the black hole candidate MAXI J0637–430 during its 2019–2020 outburst using observations with the Neutron Star Interior Composition Explorer (NICER) and the Neil Gehrels ...
  • Jana, Arghajit; Chatterjee, Arka; Kumari, Neeraj; Nandi, Prantik; Naik, Sachindra; Patra, Dusmanta (Cornell University Library, 2020-08)
    We present the results obtained from a detailed X-ray timing and spectral analysis of the Seyfert 2 galaxy NGC 6300 by using observations from the Suzaku observatory, theChandra X-ray Observatory and the Nuclear Spectroscopic ...
