Lab #7. Hubble's Law and the Cosmic Distance Scale
Students learn about Hubble's Law and the basic nature of our expanding Universe. They fit elliptical profiles to the brightest elliptical galaxies drawn from large clusters (BCGs), treating them like standard candles in order to determine their distances based on expected sizes and luminosities. They then determine redshifts from spectra, and compare the quality of their distance estimations based on statistical and direct measures.
