Atmospheric Radio Signals From Galactic Dark Matter

TL;DR

This paper proposes that antimatter quark nuggets from galactic dark matter could produce detectable radio frequency signals through synchrotron radiation caused by secondary charged particles deflected by Earth's magnetic field.

Contribution

It introduces a novel method to detect dark matter via radio signals generated by antimatter quark nuggets impacting Earth's atmosphere.

Findings

Antimatter quark nuggets can produce significant radio emissions.

Current and upcoming experiments could detect these signals.

The proposed detection method offers a new avenue for dark matter research.

Abstract

If the dark matter of our galaxy is composed of nuggets of quarks or antiquarks in a colour superconducting phase there will be a small but non-zero flux of these objects through the Earth's atmosphere. A nugget of quark matter will deposit only a small fraction of its kinetic energy in the atmosphere and is unlikely to be detectable. If however the impacting object is composed of antiquarks the energy deposited can be quite large and contain a significant charged particle content. These relativistic secondary particles will subsequently be deflected by the earth's magnetic field resulting in the emission of synchrotron radiation. This work will argue that this radiation should be detectable at radio frequencies and that present and proposed experiments are capable of detecting such a signal.
