  • The long-active afterglow of GRB 210204A: detection of the most delayed flares in a gamma-ray burst 
    Kumar, Harsh, et.al.; Gupta, Rahul; Aryan, Amar; Dimple; Ghosh, Ankur; Kumar, Amit; Mishra, Kuntal; Pandey, Shashi Bhushan; Ror, Amit Kumar (Monthly Notices of the Royal Astronomical Society, 2022-06)
    We present results from extensive broadband follow-up of GRB 210204A over the period of 30 d. We detect optical flares in the afterglow at 7.6 × 105 s and 1.1 × 106 s after the burst: the most delayed flaring ever detected ...
  • Modeling the late-time merger ejecta emission in short gamma ray bursts 
    Ghosh, Ankur; Misra, Kuntal, et.al.; Omar, Amitesh; Panchal, Dimple (Journal Astrophysical Astronomy, 2022-12)
    The short gamma ray bursts (GRBs) are the aftermath of the merger of binary compact objects (neutron star–neutron star or neutron star–black hole systems). With the simultaneous detection of gravi tational wave (GW) signal ...
  • Multiwavelength study of the luminous GRB 210619B observed with Fermi and ASIM 
    Caballero-Garcia, M. D.; Gupta, Rahul; Pandey, Shashi Bhushan, et.al.; Ror, A. Kumar; Aryan, A.; Kumar, A. (Monthly Notices of the Royal Astronomical Society, 2023-03)
    We report on detailed multiwavelength observations and analysis of the very bright and long GRB 210619B, detected by the Atmosphere-Space Interactions Monitor installed on the International Space Station and the Gamma-ray ...
  • Probing into emission mechanisms of GRB 190530A using time-resolved spectra and polarization studies: synchrotron origin? 
    Gupta, Rahul,et.al. (Monthly Notices of the Royal Astronomical Society, 2022-04)
    Multipulsed GRB 190530A, detected by the Gamma-ray Burst Monitor (GBM) and Large Area Telescope onboard Fermi, is the sixth most fluent GBM burst detected so far. This paper presents the timing, spectral, and polarimetric ...
