  • Evidence for Two Distinct Populations of Kilonova-associated Gamma-Ray Bursts 
    Dimple; Misra, K.; Arun, K. G. (Astrophysical Journal Letters, 2023-06)
    Identification of gamma-ray burst (GRB) progenitors based on the duration of their prompt emission (T90) has faced several roadblocks recently. Long-duration GRBs (with T90 > 2 s) have traditionally been thought to ...
  • 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 ...
  • Search for merger ejecta emission from late-time radio observations of short GRBs using GMRT 
    Ghosh, Ankur; Vaishnava, C. S.; Resmi, L.; Misra, Kuntal; Arun, K. G.; Omar, Amitesh; Chakradhari, N. K. (Monthly Notices of the Royal Astronomical Society, 2024-01)
    In some cases, the merger of two neutron stars can produce a rapidly rotating and highly magnetized millisecond magnetar. A significant proportion of the rotational energy deposited to the emerging ejecta can produce a ...
