Astrophysics has always been a captivating field, delving into the mysteries of the universe and providing glimpses into the workings of celestial objects. However, it is in the realm of highenergy astrophysics that the universe truly reveals its most extreme phenomena. From quasars to gammaray bursts, this subchapter explores the historical milestones that have unraveled the mysteries of highenergy astrophysics.In the early 20th century, the study of astrophysics was primarily focused on the visible light emitted by stars and galaxies. It wasnt until 1932 that the first cosmic rays, highly energetic particles from space, were discovered by physicist Victor Hess. This groundbreaking observation hinted at the existence of highenergy phenomena beyond the reach of traditional telescopes.The discovery of the first Xray source outside our solar system in 1962 marked a turning point in highenergy astrophysics. Astronomers soon realized that Xrays and gammarays, with their much higher energies than visible light, could provide vital information about the most energetic processes in the universe. Exploratory missions, such as the Uhuru satellite launched in 1970, opened a new window for studying highenergy astrophysics.The birth of Xray astronomy gave rise to incredible findings. In 1967, the first Xray pulsar, a rapidly rotating neutron star, was discovered. This revelation paved the way for understanding the behavior of matter under extreme gravitational forces. Subsequently,...
