Active Galactic Nuclei

  1. 1. Active Galactic Nuclei Chase VanAuken
  2. 2. What are AGN? <ul><li>Active Galactic Nuclei are galaxies that release an incredible amount of energy </li></ul><ul><li>The core of an AGN releases more energy then most galaxies </li></ul>
  3. 3. Why are AGN so Bright? <ul><li>AGN are very bright because they are releasing so much energy </li></ul><ul><li>Where do AGN get so much energy? </li></ul>
  4. 4. What is a Black Hole? <ul><li>A black hole is a body in space with enormous mass and gravity so powerful that not even light can escape </li></ul>
  5. 5. Super-massive Black Holes <ul><li>It is widely believed that at the center of the core of an AGN galaxy is a super-massive black hole </li></ul><ul><li>These black holes can have a mass thousands of times greater than our sun </li></ul>
  6. 6. How Does the Light Escape the Black Hole? <ul><li>The black hole is feeding off the dense star filled galactic core </li></ul><ul><li>As the stars and gasses are drawn into the black hole part of the energy is released as X-Rays and Gamma Rays </li></ul>
  7. 7. Quasars <ul><li>Quasars are one type of AGN </li></ul><ul><li>They are thought to be the oldest galaxies in the universe </li></ul><ul><li>Quasars are extremely bright </li></ul><ul><li>Two other types of AGN galaxies are Blazars and Seyferts </li></ul>
  8. 8. Why Study AGN? <ul><li>The study of AGN can give us new insight into Black Holes </li></ul><ul><li>We can study ancient galaxies and learn about our own </li></ul><ul><li>Black Holes are thought to be similar to the original mass of matter that existed at the beginning of the universe </li></ul>
