Across the cosmos, many stars can be found in pairs, gracefully circling one another. Yet one of the most dramatic pairings occurs between two orbiting black holes, formed after their massive ...

SXS—Simulating eXtreme Spacetimes—is an ongoing scientific collaboration that has been generating simulations of dramatic events in space, particularly mergers of binary black hole systems, for ...

When a black hole and a neutron star finally meet, the result is cosmic carnage—and now, thanks to Caltech’s latest supercomputer simulations, we’re getting a front-row seat to the whole terrifying ...

Despite what their names might suggest, black holes are some of the brightest objects in the universe. The glow comes from the gas and dust that flow around and into a blackhole. The most ...

Near the black hole (shown in the center), an accretion flow forms a dense, thin thermal disk embedded within a magnetically dominated envelope that helps stabilize the system. The flow is ...
