- Detecting Ultrashort Gamma-ray Bursts Originated from Ultraheavy Dark Matter Collisions
- Time: 11:00 am - 12:00 pm
- Place: 5310 Chamberlin Hall
- Speaker: Xuheng Luo, Johns Hopkins University
- 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 gamma-rays. 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 ultrashort duration and rareness. In this talk, I will discuss the strategies and prospects for detecting such ultrashort gamma-ray burst. I will also present a concrete dark matter model that produces bursts potentially detectable by the current instruments.
