The best evidence for a black hole at the center of the Galaxy also comes from the application of Kepler’s third law. Suppose a star at a distance of 20 light-hours from the center of the Galaxy has an orbital speed of 6200 km/s. How much mass must be located inside its orbit?
Suppose you were Hubble and Humason, working on the distances and Doppler shifts of the galaxies. What sorts of things would you have to do to convince yourself (and others) that the relationship you were seeing between the two quantities was a real feature of the behavior of the universe? (For example, would data from two galaxies be enough to demonstrate Hubble’s law? Would data from just the nearest galaxies-in what astronomers call “the Local Group”-suffice?)
Describe the evidence indicating that a black hole may be at the center of our Galaxy.
Imagine that an observed distant galaxy is measured to have a distance of 40 Mpc by a Type Ia supernovae and the redshift of the galaxy indicates the galaxy appears to be moving away from us at a speed of 2400 km/s. What would the Hubble constant be if measured solely based on this galaxy in units of km/s/Mpc?
If a galaxy is 18 Mpc from Earth and the Hubble constant is 70 km/s/Mpc, what is the recession velocity of the galaxy (in km/s)? A galaxy is receding from Earth at a speed of 300 km/s and the Hubble constant is 70 km/s/Mpc. What is the distance to the galaxy (in Mpc)?
Suppose you have obtained spectra of several galaxies and have measuerd the observed wavelength of the H-Alpha line (rest wavelength = 656.3 nm) to be Galaxy 1: 658.1 nm. Galaxy 2: 667.1 nm. Galaxy 3: 677.6 nm. Calculate the redshift, z, for each galaxy.

If astronomers find they have made a mistake and our Solar System is actually 7,350 pc rather than 8,300 pc from the center of the Milky Way Galaxy, but the orbital velocity of the Sun is still 225 km/s, what is the minimum mass (in solar masses, MSun) of the Galaxy within the orbit of the Sun?
