Core-collapse supernova from a possible progenitor star of 100 M
Amar Aryan, Shashi Bhushan Pandey, Abhay Pratap Yadav +3
In this work, we study the synthetic explosions of a massive star. We take a 100 M zero--age main--sequence (ZAMS) star and evolve it until the onset of core-collapse usi…
Probing into emission mechanisms of GRB 190530A using time-resolved spectra and polarization studies: Synchrotron Origin?
Rahul Gupta, S. Gupta, T. Chattopadhyay +47
Multi-pulsed GRB 190530A, detected by the GBM and LAT onboard \fermi, is the sixth most fluent GBM burst detected so far. This paper presents the timing, spectral, and polarimetric…
Photometric, polarimetric, and spectroscopic studies of the luminous, slow-decaying Type Ib SN 2012au
S. B. Pandey, Amit Kumar, Brajesh Kumar +15
Optical, near-infrared (NIR) photometric and spectroscopic studies, along with the optical imaging polarimetric results for SN 2012au, are presented in this article to constrain th…
GRB 140102A: Insight into Prompt Spectral Evolution and Early Optical Afterglow Emission
Rahul Gupta, S. R. Oates, S. B. Pandey +38
We present and perform a detailed analysis of multi-wavelength observations of \thisgrb, an optical bright GRB with an observed reverse shock (RS) signature. Observations of this G…
SN 2020ank: a bright and fast-evolving H-deficient superluminous supernova
Amit Kumar, Brajesh Kumar, S. B. Pandey +7
We investigate the observational properties of a hydrogen-deficient superluminous supernova (SLSN) SN 2020ank (at z = 0.2485), with the help of early phase observations carried out…
10.4m GTC observations of the nearby VHE-detected GRB 190829A/SN 2019oyw
Y. -D. Hu, A. J. Castro-Tirado, A. Kumar +15
Aims. GRB 190829A (z = 0.0785), detected by Fermi and Swift with two emission episodes separated by a quiescent gap of ~40 s, was also observed by the H.E.S.S. telescopes at Very-H…
