Presentation Transcript

  1. Lecture 36 – Quasars and Radio Galaxies • What is going on in radio galaxies and quasars? • What accounts for the appearance of quasars (dominated by brilliant, point-like source of radiation).

  2. Hints in the sky: 3C175 (quasar) and M87 (galaxy)

  3. M87

  4. Current Model for Luminous Extragalactic Radio Sources Supermassive black hole (1E+09 solar masses) surrounded by huge accretion disk generates jets which penetrates tens or hundreds of kiloparsecs into space

  5. At the center

  6. A quasar or radio galaxy

  7. Summary: the structure of a radio source

  8. These sources are luminous enough to be seen at the edge of the universe
