A Series Solution to the Luminosity Distance in a Flat LCDM Universe
De-Zi Liu, Nan-Nan Yue, Xiao-Lei Meng +2
Cosmological observations indicate that our universe is flat and dark energy (DE) dominated at present. The luminosity distance plays an important role in the investigation of the…

Numerical Strategies of Computing the Luminosity Distance
De-Zi Liu, Cong Ma, Tong-Jie Zhang +1
We propose two efficient numerical methods of evaluating the luminosity distance in the spatially flat ΛCDM universe. The first method is based on the Carlson symmetric form of ell…
