Pulsars as Spinning Neutron Stars

• pulsars in supernova remnants: Crab nebula, pulsar in X-rays, movie
• pointlike X-ray object in Cas A
• cartoon and movie of lighthouse model
• pulsar kicks: runaway neutron stars observed here, here, and here; simulation here

General Relativity: Relativistic Gravity

• Big Al
• Principle of Equivalence
  an especially nice animation of the rocket experiment
• gravitational redshift verified in the lab: Pound & Rebka (1960)
• The first evidence for light bending: 1919 eclipse, reported to the Royal Society and in the New York Times
• More recent evidence on galactic scales: rings, galaxy clusters here and here
