Virial clouds to explain rotational asymmetry in galactic halos

TL;DR

This paper proposes that virial temperature molecular hydrogen clouds in galactic halos could explain observed rotational asymmetries, offering a method to constrain their properties assuming a single fluid composition.

Contribution

It introduces a new approach to constrain virial clouds' parameters in galactic halos, potentially explaining rotational asymmetries observed in CMB data.

Findings

Virial clouds may account for galactic halo dark matter.

A method to constrain cloud parameters assuming a single fluid.

Potential extension of the method to multiple fluids.

Abstract

The rotation of the galactic objects has been seen by asymmetric Doppler shift in the CMB data. Molecular hydrogen clouds at virial temperature may contribute to the galactic halo dark matter and they might be the reason for the observed rotational asymmetry in the galactic halos. We present a method to constrain the parameters of these virial clouds given that they are composed of a single fluid. The method is such that it should be possible to extend it to more than one fluid.
