BLACK HOLES

By: Griffin Roelle

• It consists of 3 components– Point of singularity– Event horizon: Schwarzschild Radius

– Size: radius range from 3x the # of solar masses in it- 1 billion solar masses

What is a black hole?

Kinds of black holes

•3 types• Supermassive• Stellar• Miniature

•How are they named• Size• Location: Cygnus X-1,

Andromeda, M87, NGC 4261, and the Milky Way

• Pulling of gravity: tug of war• Supernova: implosion of star• Star/planet 20 times size of

sun• 2.5 times size of sun after

explosion= black hole

• Invisible• Gravitational

lensing• Bending of light• Gravitational pull

How are they found

Space Telescope Imaging Spectrograph (STIS): A spectrograph splits any incoming light using prisms and diffraction gratings into a rainbow.
