Resumen<\/strong><\/p>\n

Usando una simulaci\u00f3n de materia oscura cosmol\u00f3gica de un c\u00famulo de galaxias, seguimos la evoluci\u00f3n temporal de su poblaci\u00f3n de c\u00famulos globulares. Para imitar las poblaciones de c\u00famulos globulares rojos y azules, seleccionamos a alto desplazamiento al rojo (z~<\/em>1) dos conjuntos de part\u00edculas de halos gal\u00e1cticos individuales restringidos por el hecho de que, al desplazamiento al rojo z=<\/em>0, tienen perfiles de densidad similares a los observados. Al corrimiento al rojo z=<\/em>0, aproximadamente el 60 % de nuestros c\u00famulos globulares seleccionados fueron removidos de sus halos originales que forman la poblaci\u00f3n de c\u00famulos globulares dentro del c\u00famulo, mientras que el 40 % restante todav\u00eda est\u00e1 unido gravitacionalmente a sus halos gal\u00e1cticos originales. Como la poblaci\u00f3n azul es m\u00e1s extensa que la roja, la poblaci\u00f3n\u00a0de c\u00famulos globulares dentro del c\u00famulo est\u00e1 dominada por c\u00famulos globulares azules, con una fracci\u00f3n relativa que crece del 60 % al desplazamiento al rojo z=<\/em>0 hasta el 83 % para el corrimiento al rojo z~<\/em>2. De acuerdo con los resultados observacionales para el c\u00famulo de galaxias de Virgo, la poblaci\u00f3n de c\u00famulos globulares intrac\u00famulo azul est\u00e1 m\u00e1s espacialmente extendida que la roja, lo que indica un origen por destrucci\u00f3n de marea.<\/p>\n

Abstract<\/strong><\/p>\n

Using a cosmological dark matter simulation of a galaxy-cluster halo, we follow the temporal evolution of its globular cluster population. To mimic the red and blue globular cluster populations, we select at high redshift (z<\/em>\u223c1) two sets of particles from individual galactic halos constrained by the fact that, at redshift z<\/em>=0, they have density profiles similar to observed ones. At redshift z=<\/em>0, approximately 60% of our selected globular clusters were removed from their original halos building up the intra-cluster globular cluster population, while the remaining 40% are still gravitationally bound to their original galactic halos. Since the blue population is more extended than the red one, the intra-cluster globular cluster population is dominated by blue globular clusters, with a relative fraction that grows from 60\\% at redshift z<\/em>=0 up to 83% for redshift z<\/em>\u223c2. In agreement with observational results for the Virgo galaxy cluster, the blue intra-cluster globular cluster population is more spatially extended than the red one, pointing to a tidally disrupted origin.<\/p>\n
