This download is a PowerPoint and lesson plan explaining how the various distance measurements are formulated in astrophysics to create a distance ladder. Also considered are some additional ideas that support the big bank theory. Quasars are also mentioned at the end of the lesson, primarily to dispel the idea of a steady state expanding universe.
This is lesson 11 / 12 from my Astrophysics / Cosmology course, all available individually or as a bundle at a reduced price.
Red shift v = Hd
Simple interpretation as expansion of universe; estimation of age of universe, assuming H is constant.
Qualitative treatment of Big Bang theory including evidence from cosmological microwave background radiation, and relative abundance of hydrogen and helium.
Quasars as the most distant measurable objects.
Discovery of quasars as bright radio sources.
Quasars show large optical red shifts; estimation involving distance and power output.
Formation of quasars from active super-massive black holes.
