Simulating ULXs and Blazars as GRMHD Accretion Flows Around a Black Hole
General relativistic magnetohydrodynamic (GRMHD) simulations have been instrumental in our understanding of high-energy astrophysical phenomena over the past two decades.

Astrophysical Evidence for Black Holes
The case for collapsed objects in some X-ray binary systems continues to strengthen. But there is now even firmer evidence for supermassive black holes in galactic centres. Gravitational collapse seems to have occurred in the centres of most newly-forming galaxies, manifesting itself in a phase of quasar-like activity (which may be reactivated later ...

Black holes, once just fascinating theoretical predictions of how gravity warps space-time according to Einstein's theory, are now generally accepted as astrophysical realities, formed by post-supernova collapse, or as supermassive black holes ...

Cosmic necklaces in string theory and field theory
PhDIn this thesis we investigate astrophysical phenomena which arise in models with compact extra dimensions, focussing on the cosmological consequences of strings which wrap cycles in the internal space. Embedding our strings in the Klebanov-Strassler

BLACK HOLES AS PARTS OF ENTANGLED SYSTEMS
. A possible link between EPR-type quantum phenomena and astrophysical objects like black holes, under a new general definition of entanglement, is established. A new approach, involving backward time evolution and topology changes, is presented bringing
