Survey for Observations related to Black Holes

Abstract: In this paper presents a survey of key observational findings related to black hole (BH) thermodynamics and radiation. It examines landmark measurements that support the theoretical framework of BH evaporation and entropy, as well as observational missions that have captured indirect signatures of these phenomena. Furthermore, the study explores potential mechanisms through which BHs may interact with their environment, including scenarios that imply possible information exchange. Keywords: Astronomical observations, BH, Event horizon, Gravitational wave, Hawking Radiation, Jets. Title: Survey for Observations related to Black Holes Author: M. Hassan, Ayman A. Aly, A.
