Some stars are stuck in bad binary relationships. A massive primary star feeds on its smaller companion, sucking gas from…
When galaxies merge, we expect them to produce binary black holes (BBHs.) BBHs orbit one another closely, and when they…
The NSF just awarded researchers at UChicago to start developing the CMB-S4 experiment, which will map the earliest moments of…
A new study describes how astronomers discovered a supermassive black hole that suddenly "switched on" and became
Astronomers can never have enough ways to measure the expansion in the Universe, from nearby stars to distant quasars. A…
Gravitational astronomy is a relatively new discipline that has opened many doors for astronomers to understand how the huge and…
Every large galaxy in the nearby universe contains a supermassive black hole at its core. The mass of those black…
A new study suggests that pulsars could act as natural gravitational wave sensors, setting limits on supermassive black hole mergers…
Researchers have discovered an exciting new source of gravitational waves. They are the remnants left over from a supernova explosion,…
How a merged black hole rings as it settles into a stable form holds clues to a better understanding of…
