Research
Notes
•Some Hubble studies
performed using the CMBR as the reference-frame for galaxy
velocities. Heliocentric
velocities are relative to the sun, and there is still the
motion of the sun around the Milky Way (about 225 km/s) and
the motion of the Milky Way.
•Who will volunteer to do a short presentation on the MAP and PLANCK missions next week?
