Hubble Parameter Measurement Constraints on Holographic Dark Energy
We review and attempt to constrain the ΛCDM and XCDM models using 26 Hubble parameter against redshift data points from [1], [2], [3], [4] and [5]. Also known as the cosmic chronometers approach, these constraints are now almost as restrictive as or less than those from Type 1a Supernova (SN1a) appa...

| description | We review and attempt to constrain the ΛCDM and XCDM models using 26 Hubble parameter against redshift data points from [1], [2], [3], [4] and [5]. Also known as the cosmic chronometers approach, these constraints are now almost as restrictive as or less than those from Type 1a Supernova (SN1a) apparent magnitude versus redshift data [6]. Then, we attempt to constrain the Holographic Dark Energy model [7] using the aforementioned 26 H(z) measurement. Although interesting, errors for the H(z) could be less well estimated as it is a relatively new measure relative to SN1a data, which has been studied for a much longer time. |
