Black holes are a common feature of the Universe. They are observed as stellar mass black holes spread throughout galaxies and as supermassive objects in their centres. Observations of stars orbiting close to the centre of our Galaxy provide detailed clear evidence for the presence of a 4 million Solar mass black hole. Gas accreting onto distant supermassive black holes produces the most luminous persistent sources of radiation observed, outshining galaxies as quasars. The energy generated by such displays may even profoundly affect the fate of a galaxy. We briefly review the history of black holes and relativistic astrophysics before exploring the observational evidence for black holes and reviewing current observations including black hole mass and spin. In parallel we outline the general relativistic derivation of the physical properties of black holes relevant to observation. Finally we speculate on future observations and touch on black hole thermodynamics and the extraction of energy from rotating black holes.

  1. A New Approach for Testing Einstein's Theory of Gravity Close to Rapidly Spinning Black Holes

    astro-ph.HE 2026-04 unverdicted novelty 6.0 of 10

    Fast-spinning black holes can bend their disk's own thermal X-rays back onto the disk, and scattering can create a corona-free power-law tail with a distinctive polarization swing.

  2. Quantum dust cores of rotating black holes

    gr-qc 2026-01 unverdicted novelty 6.0 of 10

    Quantizing geodesic motion of dust particles in rotating black hole geometries produces many-body ground states whose core size and effective interior geometry depend on angular momentum.

  3. 2D Surface Brightness Modelling of Large 2MASS Galaxies II: The Role of Classical Bulges and Pseudobulges on Galaxy Scaling Relations and its implication for Supermassive Black Hole Formation

    astro-ph.GA 2025-02 conditional novelty 5.0 of 10

    Classical bulges and pseudobulges follow different galaxy scaling relations, and pseudobulges do not follow the black hole scaling relations defined by classical bulges and ellipticals, based on 119 nearby galaxies.
