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…
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)…
