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.
A team of top astronomers including Dr. William Alston, Senior Lecturer in Data Science at the University of Hertfordshire's Center of Astrophysics, has detected unprecedented periodic X-ray pulses from the supermassive black ...
