Aspherical supernovae [PDF]

, 2004
Although we know that many supernovae are aspherical, the exact nature of their geometry is undetermined. Because all the supernovae we observe are too distant to be resolved, the ejecta structure can't be directly imaged, and asymmetry must be inferred ...

Supernova-induced Binary-interaction-powered Supernovae: A Model for SN2022jli

The Astrophysical Journal
We present 3D hydrodynamical modelling of supernova (SN)-induced binary-interaction-powered SNe; a scenario proposed for the peculiar type Ic SN SN2022jli.

SN 2023syz and SN 2025cbj: Two Type IIn Supernovae Associated with IceCube High-energy Neutrinos

The Astrophysical Journal
Type IIn supernovae (SNe IIn) are a subclass of core-collapse SNe in which strong interactions occur between the ejecta and dense circumstellar material, creating ideal conditions for the production of high-energy neutrinos.

Pinning Down the Geometry of the Type Ic Broad-line Supernova 2026gzf

The Astrophysical Journal Letters
Type Ic broad-line supernovae (SNe Ic-BL) are often associated with energetic explosions that display a prompt outburst of high-energy emission. Since their progenitor lost the H and He envelopes before the explosion exposing the C/O core, their ...

An Extremely Bright Slow-rising Afterglow from an Off-axis Jet in GRB 260310A

The Astrophysical Journal Letters
We present a multiwavelength study of GRB 260310A, a nearby long-duration gamma-ray burst (GRB) at z  ≃  0.153 associated with a broad-lined Type Ic supernova.

The Einstein Probe Transient EP240414a: Linking Fast X-Ray Transients, Gamma-Ray Bursts, and Luminous Fast Blue Optical Transients

The Astrophysical Journal Letters
Detections of fast X-ray transients (FXTs) have accrued over the last few decades. However, their origin has remained mysterious. Rapid progress is now being made thanks to timely discoveries and localizations with the Einstein Probe mission.
