"New Methods to Detect Hawking Radiation from Black Holes"

A European research group has proposed that Hawking radiation, theorized by Stephen Hawking in 1974, could be detected using existing high-energy gamma-ray telescopes. This radiation, emitted from "black hole morsels" formed during black hole mergers, produces gamma ray bursts with a distinctive fingerprint. Detecting this radiation would provide evidence of the quantum behavior of black holes and could reveal new physics. The team plans to collaborate with experimental groups to search for these signals.

Unveiling Dark Matter's Secrets: Exploding Axion Stars and Neutron Star Debris

Researchers from Washington University in St. Louis have used observations from the collision of two neutron stars to derive new constraints on axion-like particles, which are leading candidates for dark matter. The study suggests that these exotic particles produced in the aftermath of neutron star mergers can escape and decay into photons, creating unique electromagnetic signals that can be detected by gamma-ray telescopes like NASA's Fermi-LAT. This research provides a new window of opportunity in the quest for understanding the missing matter in the universe and could lead to further insights into the nature of dark sector particles like axions.
