Neutron stars become dark matter traps in new FAST telescope search

Researchers using China’s FAST telescope have searched two nearby neutron stars for one of physics’ most elusive suspects, axion dark matter. The study turned the magnetic environments around dead stars into natural detectors, then used radio observations to listen for a faint signal that would betray a hidden particle. The team, Sinuo Gao, Chen Wang…

Scientists detect a hidden gravitational-wave signal at a black hole’s edge

A study in Nature has reported observational evidence of a hidden gravitational-wave component in GW250114, the loudest binary black hole merger detected so far. By pulling out this faint signal from the merger’s aftermath, researchers have found a new way to probe the region just outside a newly formed black hole’s event horizon. The work…
