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),…
On the Average Comoving Number Density of Halos
A. Del Popolo
I compare the numerical multiplicity function given in Yahagi, Nagashima & Yoshii (2004) with the theoretical multiplicity function obtained by means of the excursion set model and…
Measuring Omega_m using clusters evolution
A. Del Popolo
The constraints obtained by several authors (Eke et al. 1998; Henry 2000) on the estimated values of , and are revisited in the light of recent theoretical dev…
