Asymptotically safe gravity as a scalar-tensor theory and its cosmological implications
Asymptotically gravity scalar-tensor theory cosmological implications
2011/7/28
We study asymptotically safe gravity with Einstein-Hilbert truncation taking into account the renormalization group running of both gravitational and cosmological constants. We show the classical beha...
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
2011/7/20
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...
