Exam 17: Hubbles Law and Dark Matter: the Large-Scale Structure of the Cosmos

The more its central black hole was fed, the more likely the galaxy was to show up as a quasar.

Which of these is the next evolutionary track for the Large Magellanic Cloud?

Supermassive galaxies are found at the core of rich galaxy clusters.

Using binary galaxies to find their masses assumes that, like double stars, their orbits obey laws of Planetary Motion.

In its most energetic phase, a quasar can probably only last

There is no obvious evidence for large- scale structure greater than about

What is the anticipated interaction of the Milky Way and Large Magellanic cloud?

When galaxies collide, the large- scale galactic structure is affected, but most of the individual stars are not.

Redshift surveys give us

While we know of thousands of quasars, it is likely none of them still exist today. Explain.

The masses of most spiral galaxies, like ours, are a few billion solar masses.

The height of the quasar epoch was

Quasars were used to determine the size of the Local Supercluster.

The largest known galaxies contain about 10 billion solar masses.

How can close analysis of the spectra of quasars let us map the whole universe?

How can the image of a single quasar be doubled? What does that tell us about the quasar's distance?

Why would galaxies colliding in a small cluster tend to stick together, while galaxies in a large cluster tend to pass through each other?

The pregalactic blobs started with masses comparable to big globular clusters.

The result of a galactic merger depends on the of each galaxy.

Like supernovae, quasars must end with a violent explosion.
