abstract
On the basis of a large collection of detailed 3D core-collapse supernova simulations carried to late times, we identify four channels of stellar mass black hole formation. Our examples for Channel 1 involve the formation of lower-gap and above black holes in energetic asymmetric supernova explosions. Our Channel 2 example involves a modest supernova explosion that may leave behind a lower-gap to $\sim$10 $M_{\odot}$ black hole. The latter may not be easily distinguishable from ``standard" supernovae that birth neutron stars. Our Channel 3 example experiences an aborted core-collapse explosion, more often in the context of a low-metallicity progenitor, whose residue is a black hole with a mass perhaps up to $\sim$40 $M_{\odot}$. The latter may be accompanied by a pulsational-pair instability supernova (PPISN). Channel 4 is the only quiescent or ``silent" scenario for which perhaps $\sim$5 to 15 $M_{\odot}$ black holes are left. Where appropriate, we estimate $^{56}$Ni yields, explosion energies, approximate recoil speeds, and residual black hole masses. The progenitor mass density and binding energy profiles at collapse influence the outcome in a systematic way. We speculate that the statistics and prevalence of these various channels depend not only on still evolving supernova theory, but on remaining issues with the theory of massive star evolution, binary interaction, wind mass loss, metallicity, and the nuclear equation of state. Importantly, we suggest, but have not proven, that the silent channel for black hole formation may not be the dominant formation modality.

Super-Eddington accretion onto black holes and its application to fallback accretion
Spherical super-Eddington accretion onto a black hole has two analytic solution branches, an isothermal one and a power-law one, and neither branch is luminous enough to explain the observed failed supernova candidates.

Impact of rotation on the accretion of entropy perturbations in collapsing massive stars
Rotation has little effect on entropy perturbations falling onto a supernova shock: the sound and vortex waves they create stay below about 1% of the local sound speed, and convective eddies dominate for the modes tha...

Probing Dark Matter Spike with Gravitational Waves from Early EMRIs in the Milky Way Center
Dark matter's drag on black holes spiraling into the Milky Way's central black hole would weaken low-frequency and strengthen high-frequency gravitational waves, a signal LISA or Taiji could potentially detect.
