SN 2025qe: A case study of diversity in low-luminosity thermonuclear explosions
Hrishav Das, Anirban Dutta, Devendra K. Sahu +3
We present optical photometric and spectroscopic observations of SN 2025qe, a Type Iax supernova in IC 0529, monitored from to rest-frame days relative to -band ma…
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
We present a comprehensive analysis of optical photometry and medium-resolution spectroscopy for Type Ic supernovae (SNe) SN 2020akf and SN 2021mxx. Our study covers the evolution…
Decadal pre-explosion activity and circumstellar interaction in a supernova
Ting-Wan Chen, Amar Aryan, Sheng Yang +52
When a massive star explodes as a supernova, crucial information about its immediate environment is lost within hours. Here we report rapid optical observations from Lulin Observat…
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…
SN 2020udy: A new piece of the homogeneous bright group in the diverse Iax subclass
Mridweeka Singh, Devendra K. Sahu, Barnabas Barna +23
We present optical observations and analysis of a bright type Iax SN~2020udy hosted by NGC 0812. The light curve evolution of SN~2020udy is similar to other bright Iax SNe. Analyti…
Characterizing the Ordinary Broad-lined Type Ic SN 2023pel from the Energetic GRB 230812B
Gokul P. Srinivasaragavan, Vishwajeet Swain, Brendan M. O'Connor +39
We report observations of the optical counterpart of the long gamma-ray burst (LGRB) GRB 230812B, and its associated supernova (SN) SN 2023pel. The proximity () and high…
Bridging between type IIb and Ib supernovae: SN IIb 2022crv with a very thin Hydrogen envelope
Anjasha Gangopadhyay, Keiichi Maeda, Avinash Singh +26
We present optical, near-infrared, and radio observations of supernova (SN) SN~IIb 2022crv. We show that it retained a very thin H envelope and transitioned from a SN~IIb to a SN~I…
A broadband X-ray study of the dwarf nova SS Cyg during quiescence and outburst
Anirban Dutta, Vikram Rana, Koji Mukai +1
We present a broadband X-ray study (\,0.3-50 keV) of the dwarf nova SS Cyg highlighting the changes in the accretion during two phases, the quiescence and the outburst states…
