ZKDR Distance, Angular Size and Phantom Cosmology
The influence of mass inhomogeneities on the angular size-redshift test is investigated for a large class of flat cosmological models driven by dark energy plus a cold dark matter component. The results are presented in two steps. First, the mass inhomogeneities are modeled by a generalized Zeldovich-Kantowski-DyerRoeder (ZKDR) distance which is characterized by a smoothness parameter α(z) and ...
متن کاملThe angular diameter and distance of the Cepheid ζ Gem
Cepheids are the primary distance indicators for extragalactic astronomy and therefore are of very high astrophysical interest. Unfortunately, they are rare stars, situated very far from Earth. Though they are supergiants, their typical angular diameter is only a few milliarcseconds, making them very challenging targets even for long-baseline interferometers. We report observations that were ob...
متن کاملAngular size in “ quintessence ” cosmology
We investigate the influence of an exotic fluid component (" quintessence ") on the angular size-redshift relation for distant extragalactic sources. Particular emphasis is given for the redshif z m at which the angular size takes its minimal value. We derive an analytical closed form which determines how z m depends on the parameter of the equation of state describing the exotic component. The...
متن کاملAngular Diameter Distance Measurement with Galaxy Clustering in the Multipole Space
The shape of the angular power spectrum of galaxies in the linear regime is defined by the horizon size at the matter-radiation equality. When calibrated by cosmic microwave background measurements, the shape of the clustering spectrum can be used as a standard ruler to estimate angular diameter distance as a function of redshift at which galaxy clustering is measured. We apply the proposed cos...
متن کاملDistance measures in cosmology
In cosmology (or to be more specific, cosmography, the measurement of the Universe) there are many ways to specify the distance between two points, because in the expanding Universe, the distances between comoving objects are constantly changing, and Earth-bound observers look back in time as they look out in distance. The unifying aspect is that all distance measures somehow measure the separa...
