Gamma ray burst distances and the timescape cosmology
Gamma ray burst distances timescape cosmology
2011/10/20
Gamma ray bursts can potentially be used as distance indicators, providing the possibility of extending the Hubble diagram to redshifts ~7. Here we follow the analysis of Schaefer (2007), with the aim...
The curvaton scenario in Brane cosmology: model parameters and their constraints
Cosmology Intermediate Inflation Brane Curvaton
2010/11/16
We have studied the curvaton scenario in brane world cosmology in an intermediate inflationary
scenario. This approach has allowed us to find some constraints on different parameters that appear in t...
Observational constraints on Galileon cosmology
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc) High Energy Physics - Phenomenology (hep-ph) High Energy Physics - Theory (hep-th)
2010/12/23
We study the cosmology of a covariant Galileon field with five covariant Lagrangians and confront this theory with the most recent cosmological probes: the type Ia supernovae data (Constitution and Un...
