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.…
A 14-year-old Mystery: The Peculiar Case of the Engine-driven SN 2012ap
Itai Sfaradi, Raffaella Margutti, Ryan Chornock +29
We present late-time ( d) optical (Keck), X-ray (Chandra and NuSTAR), and radio (VLA, ALMA, and the uGMRT) observations of the Type Ic-BL SN 2012ap. Previous studies of…
