First CCD UBVI photometric analysis of four moderately young open clusters in the third galactic quadrant
(Wiley Blackwell Publishing, Inc, 2010-10)
We present CCD photometry in the Johnson UBV and Kron-Cousins I systems down to V~ 22.0 for the open clusters NGC 2311, Trumpler 6, NGC 2432 and BH 54 and their surrounding fields. Trumpler 6 and BH 54 have never been ...
ASteCA: Automated Stellar Cluster Analysis
(Edp Sciences, 2015)
We present the Automated Stellar Cluster Analysis package (ASteCA), a suit of tools designed to fully automate the standard tests applied on stellar clusters to determine their basic parameters. The set of functions included ...
Analysis of genetic association using hierarchical clustering and cluster validation indices
(Academic Press Inc Elsevier Science, 2017-10)
It is usually assumed that co-expressed genes suggest co-regulation in the underlying regulatory network. Determining sets of co-expressed genes is an important task, based on some criteria of similarity. This task is ...
XMM-Newton observations of NGC 3268 in the Antlia Galaxy Cluster: characterization of a hidden group of galaxies at z ~0.41
(Oxford University Press, 2018-09)
We report on a detailed X-ray study of the extended emission of the intracluster medium (ICM) around NGC3268 in the Antlia Cluster of galaxies, together with a characterization of an extended source in the field, namely a ...
PyUPMASK: An improved unsupervised clustering algorithm
(EDP Sciences, 2021-06)
Aims. We present pyUPMASK, an unsupervised clustering method for stellar clusters that builds upon the original UPMASK package. The general approach of this method makes it plausible to be applied to analyses that deal ...
Deprivation and the Dimensionality of Welfare: A Variable-Selection Cluster-Analysis Approach
(Wiley, 2015-12)
We approach the problems of measuring the dimensionality of welfare and that of identifying the multidimensionally poor, by first finding the poor using the original space of attributes, and then reducing the welfare space. ...
An analysis of the population of extended main sequence turn-off clusters in the Large Magellanic Cloud
(Wiley Blackwell Publishing, Inc, 2016-12)
We combine a number of recent studies of the extended main sequence turn-off (eMSTO) phenomenon in intermediate age stellar ($1-2$~Gyr) clusters in the Large Magellanic Cloud (LMC) in order to investigate its origin. By ...
Towards a comprehensive knowledge of the open cluster Haffner 9
(Wiley Blackwell Publishing, Inc, 2017-01)
We turn our attention to Haffner 9, aMilkyWay open cluster whose previous fundamental parameter estimates are far from being in agreement. In order to provide with accurate estimates, we present high-quality Washington CT1 ...
Solute clustering behavior between 293K and 373K in a 6082 Aluminum alloy
(Elsevier Science SA, 2016-11)
We present a systematic study of the effect of pre-ageing between 293 K and 373 K in a 6082 Aluminum alloy using mainly differential scanning calorimetry in combination with Vickers hardness and transmission electron ...
Early-type galaxies in the Antlia cluster: Catalogue and isophotal analysis
(Wiley Blackwell Publishing, Inc, 2018-06)
We present a statistical isophotal analysis of 138 early-type galaxies in the Antlia cluster, located at a distance of ~35 Mpc. The observational material consists of CCD images of four 36 ×36 arcmin2 fields obtained with ...
