Improved Lemaitre-Tolman model and the mass and turn-around radius in group of galaxies II: the role of dark energy
A. Del Popolo, Man Ho Chan
In this paper, we extend our previous study \cite{DelPopolo2021} on the Lemaitre-Tolman (LT) model showing how the prediction of the model changes when the equation of state parame…

Turnaround radius in CDM, and dark matter cosmologies II: the role of dynamical friction
Antonino Del Popolo, Man Ho Chan
This paper is an extension of the paper by Del Popolo, Chan, and Mota (2020) to take account the effect of dynamical friction. We show how dynamical friction changes the threshold…

Turnaround radius in CDM, and dark matter cosmologies with shear and vorticity
Antonino Del Popolo, Man Ho Chan, David F. Mota
We determine the relationship between the turnaround radius, , and mass, , in CDM, and in dark energy scenarios, using an extended spherical collapse model…
