Infante Física, Astronomía y Matemáticas GALAXIES { CLUSTERS In this contribution I present current results on how galaxies, groups, clustersand superclusters cluster at low (z1) redshifts. I also discuss the measured andexpected clustering evolution. In a program to study the clustering properties ofsmall galaxy structures we have identied close pairs, triplets, quadruplets, quintuplets,etc. of galaxies in the Sloan Digital Sky Survey commissioning imaging data.An analysis of the 2-point angular correlation function on an area of more than250 square deg2 show that these objects appear to be appreciably more stronglyclustered than single galaxies. 2002 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57101435 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.14 |
