Testing modified gravity models with recent cosmological observations
Wen-Shuai Zhang, Cheng Cheng, Qing-Guo Huang +4
We explore the cosmological implications of five modified gravity (MG) models by using the recent cosmological observational data, including the recently released SNLS3 type Ia sup…
