A swirling black hole surrounded by a bright, glowing accretion disk in deep space, with scattered stars and cosmic dust filling the dark background.

Electromagnetic and Gravitational Wave Signals from Merging Black Holes and Neutron Stars

Black hole-neutron star and neutron star-neutron star mergers are powerful emitters of gravitational waves, and can produce a wide range of bright electromagnetic transients. They also provide us with a remarkable environment to study nuclear interactions in the cold, dense core of neutron stars, and may significantly contribute to the production of many heavy elements whose origin remains unexplained.
