A Matter-Only Universe
- cosmic histories plotted
Radiation in the Universe
- theory: photon redshifts sketched on balloon analogy
- redshift recordholders:
- QSO at z=7.085 (Mortlock+ 2011)
- GRB at z=9.4 (Cucchiara+ 2011)
- Ultra Deep Field evidence for galaxies at z~10 (Bouwens 2011)
- Extreme Deep Field infrared evidence for a galaxy at z=11.9 (Ellis+ 2013)
- radiation energy density
- radiation pressure
The Cosmic Equation of State
Minimally Realistic(?) Cosmic Histories
- cosmic ingredients
- limiting cases: matter, radiation, curvature, Lambda domination
