1. a) Using the virial mass for a spherical distribution of stars of radius R and mass M, find how R depends on o and Lassuming some constant M/L. b) Now, assume that all ellipticals have some constant surface brightness to show that L < 04
A galaxy with a spherically symmetric distribution of matter has a mass density profile of the type p(r) ∞ 1/r, where r is the radial coordinate from the centre of the galaxy. To what type of circular velocity (r) does this correspond? Select one: a. (r) O b. c. O d. (r) ~ r (r) ~ √r (r): = constant
What are potential solutions to the missing satellites problem (i.e. solutions that solve the problem without discarding ACDM)? (Choose 3). O If simulations include a Galactic potential, fewer dark matter halos survive. Many low-mass galaxies exist, but are not bright enough to be seen by current telescopes. O Low mass galaxies merge into large galaxies and become part of their stellar halos. O The number of low mass dark matter halos that form is lower than predictions based on cosmological initial conditions. O lonizing photons from the first stars, galaxies or quasars heat gas until the pressure is too high to collapse into the smallest dark matter halos. O Dwarf galaxies stream out of voids and into clusters and superclusters where they merge into larger galaxies.

The first clue that the Galaxy contains a lot of dark matter was the observation that the orbital velocities of stars did not decreases with increasing distance from the center of the Galaxy. Construct a rotation curve for the solar system by using the orbital velocities of the planets, which can be found in Appendix F. How does this curve differ from the rotation curve for the Galaxy? What does it tell you about where most of the mass in the solar system is concentrated?
