Area spectrum of near-extremal SdS black holes via the new interpretation of quasinormal modes
Wenbo Li, Lixin Xu, Jianbo Lu
Motivated by the recent work about a new physical interpretation of quasinormal modes by Maggiore, we investigate the quantization of near-extremal Schwarzschild-de Sitter black ho…
Generalized Holographic and Ricci Dark Energy Models
Lixin Xu, Jianbo Lu, Wenbo Li
In this paper, we consider generalized holographic and Ricci dark energy models where the energy densities are given as and $ρ_{h}=3c^2M^{2}_{pl}H^2…
Time Variable Cosmological Constants from the Age of Universe
Lixin Xu, Jianbo Lu, Wenbo Li
In this paper, time variable cosmological constant, dubbed {\it age cosmological constant}, is investigated motivated by the fact: any cosmological length scale and time scale can…
Constraints on Kinematic Model from Recent Cosmic Observations: SN Ia, BAO and Observational Hubble Data
Lixin Xu, Wenbo Li, Jianbo Lu
In this paper, linear first order expansion of deceleration parameter (), constant jerk () and third order expansion of luminosity distance ($…
Cosmic Constraints on Holographic Dark Energy in Brans-Dicke Theory
Lixin Xu, Jianbo Lu, Wenbo Li
In this paper, the holographic dark energy in Brans-Dicke theory is confronted by cosmic observations from SN Ia, BAO and CMB shift parameter. The best fit parameters are found in…
Time Variable Cosmological Constants from Cosmological Horizons
Lixin Xu, Jianbo Lu, Wenbo Li
In this paper, motivated from the fact that a de Sitter cosmological boundary corresponds to a positive cosmological constant, we consider time variable cosmological constants, dub…
