A new index for clustering validation with overlapped clusters
(Pergamon-Elsevier Science Ltd, 2016-08)
External validation indexes allow similarities between two clustering solutions to be quantified. With classical external indexes, it is possible to quantify how similar two disjoint clustering solutions are, where each ...
The signature of dark energy perturbations in galaxy cluster surveys
(IOP PUBLISHING LTD, 2009)
Models of dynamical dark energy unavoidably possess fluctuations in the energy density and pressure of that new component. In this paper we estimate the impact of dark energy fluctuations on the number of galaxy clusters ...

The clusters Abell 222 and Abell 223: a multi-wavelength view
(EDP SCIENCES S A, 2010)
Context. The Abell 222 and 223 clusters are located at an average redshift z similar to 0.21 and are separated by 0.26 deg. Signatures of mergers have been previously found in these clusters, both in X-rays and at optical ...
Rotational relaxation of H2S by collision with He

NUMERICAL STUDY OF A PERTURBED EINSTEIN-DESITTER COSMOLOGICAL MODEL
(Iop Publishing Ltd, 1991-02-20)
Given the ever-increasing scale of structures discovered in the universe, we solve Einstein's equations numerically, under simplifying assumptions, to examine how this lack of uniformity affects the metric of Einstein-de ...
