Comparison between the Logotropic and $Λ$ CDM models at the cosmological scale

Pierre-Henri Chavanis, Suresh Kumar

We perform a detailed comparison between the Logotropic model [P.H. Chavanis, Eur. Phys. J. Plus 130 (2015) 130] and the $Λ$ CDM model. These two models behave similarly at large (c…

Probing the interaction between dark matter and dark energy in the presence of massive neutrinos

Suresh Kumar, Rafael C. Nunes

We consider the possibility of an interaction in the dark sector in the presence of massive neutrinos, and study the observational constraints on three different scenarios of massi…

Determining the Hubble constant from Hubble parameter measurements

Yun Chen, Suresh Kumar, Bharat Ratra

We use 28 Hubble parameter, $H (z)$ , measurements at intermediate redshifts $0.07 \leq z \leq 2.3$ to determine the present-day Hubble constant $H_{0}$ in four cosmological models. We…
