  • Absorption variability of the highly obscured active galactic nucleus NGC 4507 
    Jana, Arghajit; Ricci, Claudio; Naik, Sachindra; Tanimoto, Atsushi; Kumari, Neeraj; Chang, Hsiang-Kuang; Nandi, Prantik; Chatterjee, Arka; Safi-Harb, Samar (Royal Astronomical Society, 2022-06)
    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). ...
  • Broad-band X-ray observations of the 2018 outburst of the changing-look active Galactic nucleus NGC 1566 
    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 ...
  • Probing nuclear and circumnuclear properties of NGC 6300 using X-ray observations 
    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 ...
