Signals from rare black hole-neutron star pairs could pinpoint rate at which universe is growing, researchers say.

Black holes in these environments could combine repeatedly to form objects bigger than anything a single star could produce.

Symposium explores how novel ideas and experiments are advancing many areas of theoretical physics in newly interconnected ways.

Signals suggest black hole emits a jet of energy proportional to the stellar material it gobbles up.

MIT's Mark Vogelsberger and an international astrophysics team have created a new model pointing to black holes’ role in galaxy formation.

Findings present a puzzle as to how such a huge object could have grown so quickly.

Professor of physics describes our understanding of the expansion of the universe through “standard sirens.”

LIGO inventor and professor emeritus of physics recognized “for decisive contributions to the LIGO detector and the observation of gravitational waves.”
