Cosmological implications from the full shape of the large-scale power spectrum of the SDSS DR7 luminous red galaxies
large-scale structure of Universe – cosmology: theory – cosmology: observations – cosmological parameters
2011/10/12
We obtain cosmological constraints from a measurement of the spherically averaged power spectrum (PS) of the distribution of about 90000 luminous red galaxies (LRGs) across 7646 deg2 in the Northern G...

2011/10/12
Peculiar velocities change the expansion rate of any observer moving relative to the smooth Hubble flow. As a result, observers in a galaxy like our Milky Way can experience accelerated expansion with...
