On the nature of gravitational forces
A. Del Popolo
In this paper I show how the statistics of the gravitational field is changed when the system is characterized by a non-uniform distribution of particles. I show how the distributi…
Dark matter and structure formation a review
Antonino Del Popolo
This paper provides a review of the variants of dark matter which are thought to be fundamental components of the universe and their role in origin and evolution of structures and…
Some improvements to the spherical collapse model
Antonino Del Popolo
I study the joint effect of dynamical friction, tidal torques and cosmological constant on clusters of galaxies formation I show that within high-density environments, such as rich…
Gravitational collapse and non-self similarity in the L-T relation
A. Del Popolo
We derive the luminosity-temperature relation for clusters of galaxies by means of a modification of the self-similar model to take account of angular momentum acquisition by proto…
On the cosmological mass function theory
A. Del Popolo
This paper provides, from one side, a review of the theory of the cosmological mass function from a theoretical point of view, starting from the seminal paper of Press & Shechter (…
Evolution of the cosmological mass function in a moving barrier model
A. Del Popolo
I calculate the mass function evolution in a CDM model by means of the excursion set model and an improved version of the barrier shape obtained in Del Popolo & Gambera (1998),…
