Some generalizations of the Raychaudhuri equation
Gabriel Abreu, Matt Visser
The Raychaudhuri equation has seen extensive use in general relativity, most notably in the development of various singularity theorems. In this rather technical article we shall g…
The causal structure of spacetime is a parameterized Randers geometry
Jozef Skakala, Matt Visser
There is a by now well-established isomorphism between stationary 4-dimensional spacetimes and 3-dimensional purely spatial Randers geometries - these Randers geometries being a pa…
Entropy bounds for uncollapsed rotating bodies
Gabriel Abreu, Matt Visser
Entropy bounds in black hole physics, based on a wide variety of different approaches, have had a long and distinguished history. Recently the current authors have turned attention…
Minimal conditions for the existence of a Hawking-like flux
Carlos Barcelo, Stefano Liberati, Sebastiano Sonego +1
We investigate the minimal conditions that an asymptotically flat general relativistic spacetime must satisfy in order for a Hawking-like Planckian flux of particles to arrive at f…
Hawking-like radiation from evolving black holes and compact horizonless objects
Carlos Barcelo, Stefano Liberati, Sebastiano Sonego +1
Usually, Hawking radiation is derived assuming (i) that a future eternal event horizon forms, and (ii) that the subsequent exterior geometry is static. However, one may be interest…
