Prompt emission and early optical afterglow of VHE detected GRB 201015A and GRB 201216C: onset of the external forward shock
Amit Kumar Ror, Rahul Gupta, Martin Jelínek +19
We present a detailed prompt emission and early optical afterglow analysis of the two very high energy (VHE) detected bursts GRB 201015A and GRB 201216C, and their comparison with…
SN 2016iyc: A Type IIb supernova arising from a low-mass progenitor
Amar Aryan, S. B. Pandey, WeiKang Zheng +12
In this work, photometric and spectroscopic analyses of a very low-luminosity Type IIb supernova (SN) 2016iyc have been performed. SN 2016iyc lies near the faint end among the dist…
Tale of GRB 171010A/SN 2017htp and GRB 171205A/SN 2017iuk: Magnetar origin?
Amit Kumar, Shashi B. Pandey, Rahul Gupta +4
We present late-time optical follow-up observations of GRB 171010A/SN 2017htp ( = 0.33) and low-luminosity GRB 171205A/SN 2017iuk ( = 0.037) acquired using the 4K4K C…
Analyses of Hydrogen-stripped core-collapse supernovae using MOSFiT and MESA based tools
Amar Aryan, Shashi Bhushan Pandey, Amit Kumar +4
In this work, we employ two publicly available analysis tools to study four hydrogen(H)--stripped core--collapse supernovae (CCSNe) namely, SN 2009jf, iPTF13bvn, SN 2015ap, and SN…
Photometric studies on the host galaxies of gamma-ray bursts using 3.6m Devasthal Optical Telescope
Rahul Gupta, Shashi Bhushan Pandey, Amit Kumar +6
In this article, 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 D…
Multi-wavelength study of the luminous GRB 210619B observed with Fermi and ASIM
M. D. Caballero-García, Rahul Gupta, S. B. Pandey +28
We report on detailed multi-wavelength observations and analysis of the very bright and long GRB 210619B, detected by the Atmosphere-Space Interactions Monitor (ASIM) installed on…
The long-active afterglow of GRB 210204A: Detection of the most delayed flares in a Gamma-Ray Burst
Harsh Kumar, Rahul Gupta, Divita Saraogi +22
We present results from extensive broadband follow-up of GRB 210204A over the period of thirty days. We detect optical flares in the afterglow at 7.6 x 10^5 s and 1.1 x 10^6 s afte…
