A Collapsar-Disk Origin for GW190814

astro-ph.HE · 2026-06-22 · unverdicted · novelty 6.0

GW190814 is proposed to originate from a collapsar-disk fragment merging with the central black hole, potentially preceded by SN2019npv ~60 days earlier, yielding H0 = 70.5 (+9.2, -6.4) km/s/Mpc.

Signatures of $^{56}$Ni Mixing and Neutron-rich Ejecta in Supernovae

astro-ph.HE · 2026-06-22 · unverdicted · novelty 5.0

Multi-shell modeling shows outward 56Ni mixing produces faster brighter rises and biases one-zone fits to lower ejecta mass and higher nickel fraction, while r-process signatures in collapsars depend on placement, distribution, and viewing angle rather than always showing NIR excess.
