The High Redshift Integrated Sachs-Wolfe Effect
Jun-Qing Xia, Matteo Viel, Carlo Baccigalupi +1
In this paper we rely on the quasar (QSO) catalog of the Sloan Digital Sky Survey Data Release Six (SDSS DR6) of about one million photometrically selected QSOs to compute the Inte…
Constraining DGP Gravity from Observational Data
Jun-Qing Xia
The accelerating expansion of our universe at present could be driven by an unknown energy component (Dark Energy) or a modification of general relativity (Modified Gravity). In th…
Testing Oscillating Primordial Spectrum and Oscillating Dark Energy with Astronomical Observations
Jie Liu, Hong Li, Junqing Xia +1
In this paper we revisit the issue of determining the oscillating primordial scalar power spectrum and oscillating equation of state of dark energy from the astronomical observatio…
Early Dark Energy at High Redshifts: Status and Perspectives
Jun-Qing Xia, Matteo Viel
Early dark energy models, for which the contribution to the dark energy density at high redshifts is not negligible, influence the growth of cosmic structures and could leave obser…
