Dynamo and Jet Interconnections in GRMHD Simulations of Black Hole Accretion Disks

Abstract We present 3D general relativistic magnetohydrodynamic (GRMHD) simulations of black hole (BH) accretion disks that investigate how a magnetorotational instability (MRI)-driven dynamo regulates jet formation and evolution. Unlike typical standard and normal evolution (SAN...

Revisiting localization for BPS black hole entropy

A bstract Macroscopic computation of the degeneracy / index of a BPS black hole requires carrying out string theory path integral over the near horizon geometry of the black hole. It has been suggested that the path integral can be localized to a finite dimensional subspace using...
