Some Cosmological Tails of Collapse

TL;DR

This paper investigates how massless scalar fields behave at late times around spherically symmetric black holes with a cosmological constant, analyzing their decay patterns and compatibility with existing theoretical criteria.

Contribution

It provides new insights into the late-time decay behavior of scalar fields in black hole spacetimes with a cosmological constant, extending previous analyses to these settings.

Findings

Scalar fields exhibit specific decay tails influenced by the cosmological constant

Results align with the minimal decay requirements proposed by Brady and Poisson

The study clarifies the late-time behavior in asymptotically de Sitter and anti-de Sitter spacetimes

Abstract

We summarize the results of an investigation into the late time behavior of massless scalar fields propagating on spherically symmetric black hole spacetimes with a non-zero cosmological constant. The compatibility of these results with the `minimal requirement' of Brady and Poisson is commented upon.
