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.”
