Computing the luminosity distance via optimal homotopy perturbation method
Bo Yu, Zi-Hua Wang, De-Zi Liu +1
We propose a new algorithm for computing the luminosity distance in the flat universe with a cosmological constant based on Shchigolev's homotopy perturbation method, where the opt…
Preliminary Application of Reinsch Splines to Cosmology: Transition Redshift Determination with Simulated OHD
De-Zi Liu, Shuo Yuan, Yu Lu +1
Many schemes have been proposed to perform a model-independent constraint on cosmological dynamics, such as nonparametric dark energy equation of state (EoS) ω(z) or the decelerati…
Quadrature algorithms to the luminosity distance with a time-dependent dark energy model
Nan-Nan Yue, De-Zi Liu, Xiao-Xing Pei +3
In our previous work, we have proposed two methods for computing the luminosity distance d_{L}^Λ in LCDM model. In this paper, two effective quadrature algorithms, known as Romberg…
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…
