Astrophysical Phenomena and Observations
Astrophysical Phenomena and Observations is a research topic within Astronomy and Astrophysics. Science Explorer counts 36k research works in it since 1950. 31.8% of them reached the world's top 10% most cited for their field and year.
This cluster of papers focuses on various aspects of black hole astrophysics, including X-ray astronomy, accretion disks, event horizon imaging, gravitational lensing, stellar orbits around black holes, magnetic fields in black hole systems, relativistic jets, and X-ray spectroscopy. The research covers observations and theoretical models related to supermassive black holes at the centers of galaxies, as well as stellar-mass black holes.
