Research news on Black holes

Black holes as a research area encompass the theoretical, observational, and computational study of regions of spacetime where gravity is so intense that no matter or radiation can escape beyond the event horizon. This field investigates black hole formation, stability, and classification (stellar-mass, intermediate-mass, and supermassive), their thermodynamics, accretion physics, jet launching, and role in galaxy evolution. It also includes tests of general relativity in the strong-field regime, gravitational-wave signatures from black hole mergers, numerical relativity simulations, and horizon-scale imaging, integrating methods from relativistic astrophysics, high-energy physics, and computational modeling.

First close pair of supermassive black holes detected

Supermassive black holes at the centers of galaxies are one of the most active fields of research in astronomy. In order to accumulate their enormous masses, they must merge with each other. A research team led by Silke Britzen ...

The seven hour explosion nobody could explain

Gamma-ray bursts are the most violent explosions in the universe. In a fraction of a second, they can release more energy than the sun will emit across its entire 10-billion-year lifetime. Most are over before you've had ...

Oval orbit casts new light on black hole–neutron star mergers

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an oval path rather than a perfect circle just before they merged. This discovery challenges long-standing ...
