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 recent study in Physical Review Letters explores quantum effects on black hole thermodynamics and geometry, focusing on extending two classical inequalities into the quantum regime.
When a star moves around a supermassive black hole (SMBH) in a close elliptical orbit, it gets partially tidally disrupted every time it reaches the pericenter, emitting a series of luminous flares, known as a partial tidal ...
