{"id":"https://openalex.org/T10744","display_name":"Astrophysical Phenomena and Observations","description":"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.","keywords":[{"id":"https://openalex.org/keywords/x-ray-sources","display_name":"X-ray sources","score":0.7474},{"id":"https://openalex.org/keywords/chandra-source-catalog","display_name":"Chandra Source Catalog","score":0.9868},{"id":"https://openalex.org/keywords/faint-source-detection","display_name":"faint source detection","score":0.9811},{"id":"https://openalex.org/keywords/observation-stacking","display_name":"observation stacking","score":0.9905},{"id":"https://openalex.org/keywords/active-galactic-nuclei","display_name":"active galactic nuclei","score":0.3236},{"id":"https://openalex.org/keywords/x-ray-binaries","display_name":"X-ray binaries","score":0.7699},{"id":"https://openalex.org/keywords/accretion-disks","display_name":"accretion disks","score":0.6336},{"id":"https://openalex.org/keywords/relativistic-jets","display_name":"relativistic jets","score":0.5243},{"id":"https://openalex.org/keywords/x-ray-emission","display_name":"X-ray emission","score":0.2375},{"id":"https://openalex.org/keywords/supermassive-black-holes","display_name":"supermassive black holes","score":0.4487},{"id":"https://openalex.org/keywords/neutron-stars","display_name":"neutron stars","score":0.2941},{"id":"https://openalex.org/keywords/acis","display_name":"ACIS","score":0.9385},{"id":"https://openalex.org/keywords/cataclysmic-variables","display_name":"cataclysmic variables","score":0.4787},{"id":"https://openalex.org/keywords/black-holes","display_name":"black holes","score":0.2028},{"id":"https://openalex.org/keywords/x-ray-variability","display_name":"X-ray variability","score":0.7267},{"id":"https://openalex.org/keywords/x-ray-spectra","display_name":"X-ray spectra","score":0.3799},{"id":"https://openalex.org/keywords/black-hole-accretion","display_name":"black hole accretion","score":0.6474},{"id":"https://openalex.org/keywords/galactic-center","display_name":"Galactic Center","score":0.3728},{"id":"https://openalex.org/keywords/x-ray-observations","display_name":"X-ray observations","score":0.3546},{"id":"https://openalex.org/keywords/low-mass-x-ray-binaries","display_name":"low-mass X-ray binaries","score":0.7517},{"id":"https://openalex.org/keywords/quasars","display_name":"quasars","score":0.2083},{"id":"https://openalex.org/keywords/sgr-a","display_name":"Sgr A*","score":0.6439},{"id":"https://openalex.org/keywords/accretion","display_name":"accretion","score":0.3753},{"id":"https://openalex.org/keywords/gravitational-lensing","display_name":"gravitational lensing","score":0.2129},{"id":"https://openalex.org/keywords/x-ray-pulsars","display_name":"X-ray pulsars","score":0.5821}],"legacy_keywords":"Black Holes;
