Dark Matter near gravitating bodies

TL;DR

This paper demonstrates that dark matter density and current are significantly enhanced near massive astronomical objects like neutron stars and black holes, potentially making dark matter interactions observable.

Contribution

It reveals that gravitational fields of dense bodies can amplify dark matter effects, a novel insight into dark matter behavior near extreme objects.

Findings

Dark matter density increases near neutron stars and black holes.

Enhanced dark matter effects could be detectable observationally.

Gravitational interactions influence dark matter distribution significantly.

Abstract

In this paper, we show that in the vicinity of certain astronomical bodies, e.g., a Neutron Star, a Black Hole, there exist significant enhancements of Dark Matter's density and current, due to its interaction with the gravitational field of the bodies. This enhancement implies that the effects of Dark Matter - Normal Matter interactions are enhanced and hence might be observable.
