Constraints on cosmological parameters through clusters XLF and XTF
A. Del Popolo, N. Ercan
In this paper, I revisit the constraints obtained by several authors (Reichart et al. 1999; Eke et al. 1998; Henry 2000) on the estimated values of , and in th…
X-ray temperature distribution function of clusters in presence of large non-radial motions
A. Del Popolo, M. Gambera
We consider the non-radial motions, originating in the outskirts of clusters of galaxies and we show how it may reduce the discrepancy between Cold Dark Matter (CDM) predicted X-ra…
Dark Matter Halos in a Secondary Infall Model
A. Del Popolo, M. Gambera
We calculate the density profiles of virialized halos in the case of structure evolving hierarchically from a scale-free Gaussian delta-field having a power spectrum $P(k)\propto k…
ABS Methods and ABSPACK for Linear Systems and Optimization, a Review
Emilio Spedicato, Elena Bodon, Antonino Del Popolo +1
ABS methods are a large class of methods, based upon the Egervary rank reducing algebraic process, first introduced in 1984 by Abaffy, Broyden and Spedicato for solving linear alge…
High velocity clumps and cluster of galaxies evolution
A. Del Popolo, M. Gambera
We study the effect of the interaction between small scale clumps having velocities larger than the average escape velocity v_{\rm esc} and bound clumps (having v<v_{\rm esc}), on…
On the statistics of the gravitational field
A. Del Popolo
In this paper we extend Chandrasekhar and von Neumann's analysis of the statistics of the gravitational field to systems in which particles (e.g. stars, galaxies) are not homogeneo…
