GRB 260310A/SN 2026fgk: Photometric and Spectroscopic Evolution of a Nearby Gamma-Ray Burst Supernova and an Exceptionally Bright Afterglow at z = 0.153

The Astrophysical Journal
The association of broad-lined Type Ic (Ic-BL) supernovae with long-duration gamma-ray bursts (GRBs) has been known for 28 yr. However, only about 70 GRB supernovae (GRB-SNe) have been identified, of which only one-half have spectroscopic classifications.

Interacting Binary Stars as Progenitors for Interacting Supernovae

The Astrophysical Journal Letters
Dense, compact circumstellar media (CSM) are required to power strongly interacting supernovae (SNe), yet their physical origin remains uncertain. We present a systematic study of binary stellar evolution models computed with MESA , demonstrating that ...

Exclusion of a Direct Progenitor Detection for the Type Ic SN 2017ein Based on Late-time Observations

The Astrophysical Journal Letters
To date, SN 2017ein is the only Type Ic supernova with a directly identified progenitor candidate. This candidate points to a very massive (>45 M _⊙ ) Wolf–Rayet (WR) progenitor, but its disappearance after the explosion of SN 2017ein remains unconfirmed.

Unifying the Circumstellar Environment in Broad-lined Type Ic Radio Supernovae toward Off-axis Gamma-Ray Burst Exploration

The Astrophysical Journal
Decades have passed since the first confirmed association between a broad-lined Type Ic supernova (Type IcBL SN) and a long gamma-ray burst (GRB), and the number of known GRB-SN associations has steadily increased.

EP250108a/SN 2025kg: A Jet-driven Stellar Explosion Interacting with Circumstellar Material

The Astrophysical Journal Letters
We present optical, radio, and X-ray observations of EP250108a/SN 2025kg, a broad-line Type Ic supernova (SN Ic-BL) accompanying an Einstein Probe (EP) fast X-ray transient at z = 0.176.

Late Jets, Early Sparks: Illuminating the Premaximum Bumps in Superluminous Supernovae

The Astrophysical Journal Letters
Superluminous supernovae (SLSNe) radiate ≳10–100 times more energy than ordinary stellar explosions, implicating a novel power source behind these enigmatic events.
