Stellar clusters multicolor photometry at OAUNI
(Universidad Nacional de Ingeniería, 2019-06-06)
In this work we present preliminary analysis of the astronomical photometry program for stellar clusters observed at OAUNI on the last years. Up to date twelve open clusters and nine globular clusters have been observed, ...
Intra-cluster Globular Clusters in a Simulated Galaxy Cluster
(IOP Publishing, 2018-01)
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 ...

How Many Clusters: A Validation Index for Arbitrary-Shaped Clusters
(IEEE Computer Society, 2013-04)
Clustering validation indexes are intended to assess the goodness of clustering results. Many methods used to estimate the number of clusters rely on a validation index as a key element to find the correct answer. This paper ...
Tidal stripping of globular clusters in a simulated galaxy cluster
(IOP Publishing, 2015-06)
Using a cosmological N-body numerical simulation of the formation of a galaxy-cluster-sized halo, we analyze the temporal evolution of its globular cluster population. We follow the dynamical evolution of 38 galactic dark ...
