TL;DR
This paper proposes that ultraheavy dark matter collisions produce brief, intense gamma-ray bursts that can be detected with existing telescopes, offering a new way to explore dark matter properties beyond current limits.
Contribution
It introduces a novel detection method for ultraheavy dark matter via brief gamma-ray bursts and suggests existing telescopes can be adapted for this purpose.
Findings
Detection of potential dark matter bursts with IACTs and PANOSETI
Probing new dark matter parameter space beyond current limits
Presentation of a concrete dark matter model producing detectable bursts
Abstract
Dark matter may exist today in the form of ultraheavy composite bound states. Collisions between such dark matter states can release intense bursts of radiation that includes gamma-rays among the final products. Thus, indirect-detection signals of dark matter may include unconventional gamma-ray bursts. Such bursts may have been missed not necessarily because of their low arriving gamma-ray fluxes, but rather their briefness and rareness. We point out that intense bursts whose non-detection thus far are due to the latter can be detected in the near future with existing and planned facilities. In particular, we propose that, with slight experimental adjustments and suitable data analyses, imaging atmospheric Cherenkov telescopes (IACTs) and Pulsed All-sky Near-infrared and Optical Search for Extra-Terrestrial Intelligence (PANOSETI) are promising tools for detecting such rare, brief, but…
