  • GRB 210217A: a short or a long GRB? 
    Panchal, Dimple; Mishra, Kuntal; Ghosh, Ankur; Arun, K. G.; Gupta, Rahul; Kumar, Amit; Resmi, L.; Pandey, S. B. (Journal of Astrophysics & Astronomy, 2022-12)
    Gamma-ray bursts are traditionally classified as short and long bursts based on their T90 value (the time interval during which an instrument observes 5% to 95% of gamma-ray/hard X-ray fluence). However, T90 is dependent ...
  • Photometric studies on the host galaxies of gamma-ray bursts using 3.6m Devasthal optical telescope 
    Gupta, Rahul; Pandey, Shashi Bhushan; Kumar, Amit; Ror, Amit Kumar; Aryan, Amar; Shrama, Saurabh; Misra, Kuntal; Castro- Tirado, A. J.; Tiwari, S.N. (Journal Astrophysical Astronomy, 2022-12)
    In this paper, we present multi-band photometric observations and analysis of the host galaxies for a sample of five interesting gamma-ray bursts (GRBs) observed using the 3.6m Devasthal optical telescope (DOT) and the ...
  • Revealing nature of GRB 210205A, ZTF21aaeyldq (AT2021any) and follow-up observations with the 4K 4K CCD imager + 3.6m DOT 
    Gupta, Rahul; Kumar, Amit; Pandey, Shashi Bhushan, et.al.; Ghosh, Ankur; Dimple; Misra, Kuntal; Kumar, Brajesh; Aryan, Amar (Journal Astrophysical Astronomy, 2022-06)
    Optical follow-up observations of optical afterglows of gamma-ray bursts are crucial to probe the geometry of outflows, emission mechanisms, energetics and burst environments. We performed the follow-up observations of ...
