Evidence for Black Holes
- X-ray binaries: Cygnus X-1
- Milky Way center:
- Radio overview
- The power of adaptive optics
- Stellar orbits: Munich group, UCLA group
- possibly related: gamma-ray bubbles
- other galaxies
- active galaxies: M87; AGN gallery
- gravitationally lensed quasar: the Einstein cross
- quasar and host galaxies
- supermassive black holes
- black holes and galaxies somehow know about each other
- an important clue? a binary supermassive black hole pair!
- Gravitational radiation
Hulse & Taylor's award-winning binary pulsar
gravity-wave observatories: LIGO (operational) and LISA (future)
Changing Gears: The Big Picture
Our Milky Way Galaxy
Our Place in the Milky Way
- The naked eye Milky Way:
southern hemisphere, zoom to dark lanes, more bands - Galileo: telescope
- Immanuel Kant
- William Hershel's model (top view)
- Harlow Shapley globular cluster distribution: on the sky, in space
- interstellar dust:
microscopic view,
in a dark cloud
and reflection nebula
another example of scattering and absorption - simulated view of Milky Way seen from outside; a possible similar galaxy
