X-Ray Spectral Variability of the TeV HBL Blazar PG 1553+113 with XMM-Newton
P. U. Devanand, Alok C. Gupta, Paul J. Wiita +2
We present an extensive X-ray spectral variability study of the TeV photon-emitting high-energy-peaked BL Lacertae object PG 1553+113, using the data from EPIC-PN camera of XMM-New…
SN 2021tsz: A luminous, short photospheric phase Type II supernova in a low-metallicity host
R. Dastidar, G. Pignata, N. Dukiya +14
We present the analysis of the luminous Type II Supernova (SN) 2021tsz, which exploded in a low-luminosity galaxy. It reached a peak magnitude of -18.88 0.13 mag in the b…
X-Ray Spectral Variability of Thirteen TeV High Energy Peaked Blazars with XMM-Newton
P. U. Devanand, Alok C. Gupta, V. Jithesh +2
We present a comprehensive study of the X-ray spectral variability observed in 13 TeV photon emitting high energy peaked BL Lacs(HBLs). These data come from 54 XMM-Newton EPIC-PN p…
An Intermediate Luminosity GRB 210210A: The early onset of the external forward shock in the X-ray?
Rahul Gupta, A. K. Ror, S. B. Pandey +5
We have analyzed the prompt and afterglow characteristics of the intermediate luminosity burst ``GRB 210210A". Our prompt emission analysis indicates that GRB 210210A is among the…
Testing particle acceleration in blazar jets with continuous high-cadence optical polarization observations
Ioannis Liodakis, Sebastian Kiehlmann, Alan P. Marscher +44
Variability can be the pathway to understanding the physical processes in astrophysical jets, however, the high-cadence observations required to test particle acceleration models a…
SN 2019nyk: A rapidly declining Type II supernova with early interaction signatures
Raya Dastidar, Giuliano Pignata, Naveen Dukiya +9
We present an optical photometric and spectroscopic analysis of the fast-declining hydrogen-rich Type II supernova (SN) 2019nyk. The light curve properties of SN 2019nyk align well…
Recent observations of peculiar Gamma-ray bursts using 3.6 m Devasthal Optical Telescope (DOT)
Rahul Gupta, S. B. Pandey, Amit K. Ror +2
India has been actively involved in the follow-up observations of optical afterglows of gamma-ray bursts (GRBs) for more than two decades, using the country's meter-class facilitie…
