Accretion-powered flares from black hole-disk collisions in galactic nuclei
Joaquin Pelle, Kyohei Kawaguchi, Masaru Shibata +1
Black hole impacts on accretion disks in galactic nuclei can power luminous transients, but predicting their observable signatures is challenging because the post-collision flow is…

Black hole-accretion disk collision in general relativity: Axisymmetric simulations
Alan Tsz-Lok Lam, Masaru Shibata, Kyohei Kawaguchi +1
Motivated by recent discoveries of X-ray quasi-periodic eruptions, we revisit the collision of a black hole and an accretion disk. Assuming that they are orbiting a supermassive bl…
