Abstract: Black holes are predictions of general relativity and represent a unique yet ubiquitous class of objects in the universe. Nearly every galaxy hosts at least one supermassive black hole at its center. The gas surrounding a black hole falls toward it due to the black hole’s intense gravity. This process, known as accretion, serves as the physical mechanism behind many high-energy astrophysical phenomena. Remarkably, even under such extreme gravitational conditions, most accreted gas does not cross the event horizon but is instead expelled in powerful outflows. In this talk, I will introduce fundamental concepts of black hole accretion, with a dedicated focus on the origin and dynamics of outflows.
