Causal Structures of Dynamic Black Holes

TL;DR

This paper explores the causal structures and geodesic behaviors of dynamic black holes, including evaporating and accreting cases, to understand their macroscopic quantum and gravitational phenomena.

Contribution

It provides new insights into the causal diagrams and geodesic motions of dynamic black holes, including a novel Penrose diagram for accreting black holes.

Findings

Analysis of geodesic motions on evaporating black holes

Presentation of a final Penrose diagram for an accreting black hole

Insights into the causal structures of dynamic black holes

Abstract

Dynamic space-times, especially those manifesting horizons, provide useful laboratories for examining how macroscopic quantum behaviors consistently co-generate gravitational phenomena. For this reason, the behaviors and large-scale causal structures of spatially coherent dynamic black holes will be explored in this presentation. Geodesic motions on an evaporating black hole will also be presented. Research recently completed with Beth Brown, including her final Penrose diagram for an accreting black hole, will be presented.
