Can We Find the Emission Mechanism Behind the Extremely Bright GRB 230812B?
Utkarsh Pathak, Sameer K. Patil, Hitesh Tanenia +23
GRB 230812B is a bright long-duration GRB with a luminous, long-lived afterglow and an AstroSat/CZTI polarization measurement during the prompt phase, enabling a joint study of its…
Photometric and Spectroscopic Studies of Type Ic Supernovae SN 2020akf and SN 2021mxx
Mulchand Kurre, K. R. Sahu, Shrutika Tiwari +8
The paper presents optical photometry and medium‑resolution spectroscopy of the Type Ic supernovae SN 2020akf and SN 2021mxx, deriving their light‑curve properties, ejecta velociti…
SN 2025aico: Early observations of a faint Type IIb supernova with a low-mass envelope
J. -W. Zhao, A. Pastorello, B. Kumar +45
We aimed to investigate the physical properties and the underlying explosion mechanisms of the Type IIb SN 2025aico. Through a comprehensive analysis of early-phase optical light c…
Subluminous Type IIP SN 2024abfl as a Result of a Significantly Low-energy Fe-core Collapse
Rishabh Singh Teja, D. K. Sahu, G. C. Anupama +7
We present extensive, well-sampled multiwavelength photometric and low-resolution optical spectroscopic observations of the low-luminosity Type IIP supernova SN 2024abfl. SN 2024ab…
Two years of shock interaction tracing three phases of evolution: the explosion of a Type IIn supernova, SN 2019vxm
Gitika Rameshan, Rishabh Singh Teja, D. K. Sahu +10
We present multi-wavelength photometric and optical spectroscopic observations of the long-lived interacting supernova SN 2019vxm, spanning more than two years after the explosion.…
Unveiling SN 2022eyw: A Bright Member of the Type Iax Supernova Subclass
Hrishav Das, Devendra K. Sahu, Anirban Dutta +3
We present comprehensive photometric and spectroscopic observations of Supernova (SN) 2022eyw, a luminous member of the Type Iax SN subclass. SN 2022eyw reached a peak absolute mag…
