Nearby Supernovae: Damage and Detection

• threat: ionizing radiation and ozone damage
• signature: live radioactivity deposit by blast
• evidence: ⁶⁰Fe pulse in deep ocean crusts, the Moon, and Antarctic snow

Supernovae in the Great Survey Era

• telescope field of view and pointed vs survey observations
• LSST: artist's conception, real-time webcam, supernova search engine

The Central Object

• what survives collapse? Baade & Zwicky (1934a) and (1934b)
• LGM-1? Hewish, Bell, et al (1968)
• pulses sonified
• implications of short periods

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
• runaway neutron stars: Guitar Nebular

General Relativity: Relativistic Gravity

• Big Al
• Principle of Equivalence
  an especially nice animation of the rocket experiment
• 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
