Active Galactic Nuclei
Active Galactic Nuclei (AGN) are incredibly bright centers found in some galaxies, where supermassive black holes consume surrounding material, emitting vast amounts of energy. This process produces intense radiation across the electromagnetic spectrum, including X-rays and gamma rays, making AGN some of the most luminous objects in the universe. They serve as important laboratories for studying high-energy astrophysics, helping scientists understand black hole growth, galaxy evolution, and fundamental physics in extreme environments. AGN come in various types, including quasars, which are particularly energetic and distant, providing insight into the universe's history.

Active galactic nuclei (AGN) are extremely bright regions at the centers of some galaxies, powered by supermassive black holes consuming surrounding gas and dust. As matter falls into the black hole, it heats up and emits intense radiation across the electromagnetic spectrum, making AGN among the brightest objects in the universe. They can vary in appearance, leading to types like quasars and blazars. AGN play a crucial role in galaxy formation and evolution, influencing their host galaxies and surrounding environments through the energy they release.
