Quick Reminders:

• Neutron stars: small and faint, so how detect?

  • Pulsars: neutron stars spinning incredibly fast!
    • b0329.au
    • crab.au
    • 0833.wav
    • j0437.au
    • b1937.au

• Black Holes: no light escapes, so how detect?

  • Matter falling into a black hole would get hot and emit X-rays, which would reach us (emitted before material reaches the event horizon)
