A Superfluid Dark Matter Cosmic String Wake

TL;DR

This paper investigates how superfluid dark matter influences the formation and structure of cosmic string wakes, including effects on baryon distribution, within a framework compatible with MONDian galaxy rotation curves.

Contribution

It introduces a model analyzing superfluid dark matter effects on cosmic string wakes, incorporating quantum and regular pressure, and explores implications for baryon distribution.

Findings

Superfluid dark matter affects the density profile of cosmic string wakes.

Quantum pressure terms significantly influence wake structure.

Results are consistent with MONDian galaxy rotation curves.

Abstract

We study the effects of superfluid dark matter on the structure of a cosmic string wake, considering both the effects of regular and quantum pressure terms. We consider the total fluid to consist of a combination of baryons and dark matter. Hence, we are also able to study the effects of superfluid dark matter on the distribution of baryons inside the wake. We focus on parameter values for the superfluid dark matter which allow a MONDian explanation of galaxy rotation curves.
