Multi-epoch pre-explosion images show a variable yellow supergiant candidate, with a 0.7 magnitude F814W decline from 2001 to 2013 and later g/r/z brightness fluctuations, as the likely progenitor of SN2024abfo.
New adaptive-optics MUSE data show the compact region D1 in the merger II Zw 096 has optical line ratios requiring an obscured AGN in addition to a starburst, and reveal the system as a multi-galaxy, two-stage merger.
Stellar rotation lowers the minimum progenitor mass for black hole formation and caps the maximum black hole mass near 45 solar masses for metal-poor rotating stars.
SLSN 2021bnw is best fit by a core-collapse explosion of a star with initial mass at least 61 solar masses, ejecta of 15-22.5 solar masses containing 1.7 solar masses of nickel-56 and 4 foe energy colliding with 7 solar masses of circumstellar matter.

Impact of the Rotation and Compactness of Progenitors on the Mass of Black Holes

Helium superluminous SN 2021bnw : an explosion of a massive star with a pre-outburst
SLSN 2021bnw is best fit by a core-collapse explosion of a star with initial mass at least 61 solar masses, ejecta of 15-22.5 solar masses containing 1.7 solar masses of nickel-56 and 4 foe energy colliding with 7 solar masses of circumstellar matter.
