"Cutting-Edge Detectors: Unveiling Dark Matter with Advanced Gravitational Wave Technology"
Originally Published 2 years ago — by Phys.org
Researchers from Cal Tech's Walter Burke Institute for Theoretical Physics propose using next-generation gravitational wave detectors to study dark matter. These detectors could potentially detect signals affected by ultra-heavy dark matter particles, which interact with gravity. The researchers calculate the effects of the Doppler effect, Shapiro delay, and Einstein delay on gravitational waves caused by dark matter. They suggest that upcoming GW observatories, such as the GQuEST experiment at CalTech, could detect transiting dark matter if it is considered "ultra-heavy." Additionally, these detectors may also help constrain the existence of a theoretical fifth fundamental force known as the Yukawa interaction, which operates between dark matter and traditional particles.
