A number of parameters shown linearly against time for an (approximately) concordance model. Note the highly compressed relation between redshift and time for high redshifts. The comoving Hubble parameter, Hco, shows the velocity of a galaxy that is currently at 1 Mpc (so it shows the slow-down, then speed-up, transitioning near z ~ 0.8). The final column gives the angular size of 10kpc in arcsec, which goes through a minimum near z ~ 1.6.
