The Type IIn SN 2025cbj coincidence with the high-energy neutrino IceCube-250421A
S. Garrappa, E. A. Zimmerman, T. Wasserman +14
Context. The origin of the astrophysical high-energy neutrino flux remains uncertain. Core-collapse supernovae with strong CSM interaction (Type IIn) are compelling candidates for…
Supernovae Exploding within Dense Extended Material: Early Emission Regimes and Degeneracies in Parameter Inference from Observations
Tal Wasserman, Eli Waxman
Early light curves of many core-collapse supernovae (SNe) are thought to be powered by the interaction of the shock wave with optically thick extended material, either a bound enve…
The Optical to X-ray Luminosity and Spectrum of Supernova Wind Breakouts
Tal Wasserman, Nir Sapir, Peter Szabo +1
Observations indicate that optically thick circum-stellar medium (CSM) at radii of cm around Type II core-collapse supernovae (SN) progenitors is common (and may…
Shock breakouts from compact CSM surrounding core-collapse SN progenitors may contribute significantly to the observed TeV neutrino background
E. Waxman, T. Wasserman, E. Ofek +1
Growing observational evidence suggests that enhanced mass loss from the progenitors of core-collapse supernovae (SNe) is common during yr preceding the explosion, creating…
