Revisit of constraints on holographic dark energy:SNLS3 dataset with the effects of time-varying β and different light-curve fitters被引量：3
《Science China(Physics,Mechanics & Astronomy)》2015年第1期150-160,共11页WANG Shuang GENG JiaJia HU YiLiang ZHANG Xin 
supported by the National Natural Science Foundation of China(Grant Nos.11405024 and 11175042);the Fundamental Research Fundsfor the Central Universities(Grant Nos.N130305007 and N120505003)
Previous studies have shown that for the Supernova Legacy Survey three-year （SNLS3） data there is strong evidence for the redshifl- evolution of color-luminosity parameter β of type Ia supernovae （SN Ia）. In this...

新Agegraphic快子暗能量模型再探讨
《天文与天体物理》2013年第2期9-13,共5页崔晶磊 张敬飞 
国家自然科学基金(11175042)支持。
新agegraphic暗能量模型是依据量子力学的不确定性关系和广义相对论中的引力效应提出的。作为暗能量的候选者之一,动力学标量场被认为是暗能量基本理论的有效描述。本文把新agegraphic暗能量和标量场对应起来,构造具有新agegraphic暗能...
