Active Galactic Nuclei (AGN)
AGN are incredibly energetic objects located at the center of galaxies, powered by supermassive black holes. As these black holes consume surrounding matter, it forms an accretion disk, a swirling vortex of gas and dust. This process generates tremendous energy, producing intense radiation across the electromagnetic spectrum.
AGN Jets: The Cosmic Powerhouses
Within the accretion disk, strong magnetic fields arise, channeling and accelerating a portion of the accreted material into powerful jets. These jets, composed of charged particles traveling at near-light speed, can extend for thousands of light-years, impacting the surrounding galaxy and the intergalactic medium.
Impact on Galaxies
AGN jets, with their immense energy, significantly influence the evolution of galaxies.
- Heating: Jets collide with the surrounding gas, heating it to millions of degrees, creating enormous bubbles and cavities.
- Star Formation: While heating can inhibit star formation in some regions, in others, compression triggered by jets can lead to the formation of new stars.
- Shape and Structure: Jets contribute to the shape and structure of galaxies, influencing the distribution of matter and determining their final appearance.
