Lumina runs a 500 cMpc radiation-hydrodynamic simulation combining IllustrisTNG galaxy formation with six-bin M1 radiation transport to predict late stellar-driven HI reionization ending around z=4.75 and AGN-driven HeII reionization nearly complete by z=3.
No evidence for core-collapse formed low-spin IMBHs in GWTC-4, with 90% upper limit on merger rate of 0.077 Gpc^{-3} yr^{-1}, low-spin BH mass truncation at 65 solar masses consistent with pair-instability gap lower edge, and high-spin IMBHs from hierarchical mergers.
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.

Introducing the Lumina project: large-volume radiation-hydrodynamic simulations of the epochs of hydrogen and helium reionization
Lumina runs a 500 cMpc radiation-hydrodynamic simulation combining IllustrisTNG galaxy formation with six-bin M1 radiation transport to predict late stellar-driven HI reionization ending around z=4.75 and AGN-driven HeII reionization nearly complete by z=3.

How do the LIGO-Virgo-KAGRA's Heavy Black Holes Form? No evidence for core-collapse Intermediate-mass black holes in GWTC-4
No evidence for core-collapse formed low-spin IMBHs in GWTC-4, with 90% upper limit on merger rate of 0.077 Gpc^{-3} yr^{-1}, low-spin BH mass truncation at 65 solar masses consistent with pair-instability gap lower edge, and high-spin IMBHs from hierarchical mergers.

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.
