Stellar Population Properties of ETGs in Compact Groups of Galaxies
Tatiana C. Moura, Reinaldo R. de Carvalho, Sandro B. Rembold +6
We present results on the study of the stellar population in Early-Type galaxies (ETGs) belonging to 151 Compact Groups (CGs). We also selected a field sample composed of 846 ETGs…
The Mass Density Profile and Star Formation History of Gaussian and Non-Gaussian Clusters
R. R. de Carvalho, A. P. Costa, T. C. Moura +1
This paper is the third of a series in which we investigate the discrimination between Gaussian (G) and Non-Gaussian (NG) clusters, based on the velocity distribution of the member…
Gradient Pattern Analysis Applied to Galaxy Morphology
Reinaldo. R. Rosa, Reinaldo. R. de Carvalho, Rubens. A. Sautter +6
Gradient pattern analysis (GPA) is a well-established technique for measuring gradient bilateral asymmetries of a square numerical lattice. This paper introduces an improved versio…
Bayesian surface photometry analysis for early-type galaxies
D. H. Stalder, Reinaldo R. de Carvalho, Martin D. Weinberg +4
We explore the application of Bayesian image analysis to infer the properties of an SDSS early-type galaxy sample including AGN. We use GALPHAT (Yoon et al. 2010) with a Bayes-fact…
Investigating the Relation between Galaxy Properties and the Gaussianity of the Velocity Distribution of Groups and Clusters
R. R. de Carvalho, A. L. B. Ribeiro, D. Stalder +3
We investigate the dependence of stellar population properties of galaxies on group dynamical stage for a subsample of Yang catalog. We classify groups according to their galaxy ve…
Improving galaxy morphology with machine learning
P. H. Barchi, F. G. da Costa, R. Sautter +4
This paper presents machine learning experiments performed over results of galaxy classification into elliptical (E) and spiral (S) with morphological parameters: concetration (CN)…
