Cluster views of the high redshift universe: Transcript


Leonidas Moustakas JPLCaltech CLASH London 2013 leonidasjplnasagov 1 2013 California Institute of Technology Government sponsorship acknowledged Two goals in the highredshift game. The Cosmic Time Machine. Astronomical telescopes can’t help viewing the past.. . Distance and time are always mixed in astronomical observations.. The finite speed of light means that we always see things after they have happened–a delay of 8 minutes for the Sun and about 12 billion years for the most distant galaxies we can observe. In other words,. Homogeneous and uniform cosmic expansion . Hubble constant determines scale factor . Hubble diagram was based on a limited distance scale calibrated by Cepheid variable stars in relatively nearby galaxies. Constraining Dark Energy with intermediate-. redshift. probes. Hubert .
