Statistical analysis of dwarf galaxies and their globular clusters in the local volume.

CHATTOPADHYAY T., SHARINA M. and KARMAKAR P.

Abstract (from CDS):

Although morphological classification of dwarf galaxies into early and late types can account for some of their origin and characteristics, this does not aid the study of their formation mechanism. Thus an objective classification using principal component analysis together with K means cluster analysis of these dwarf galaxies and their globular clusters (GCs) is carried out to overcome this problem. It is found that the classification of dwarf galaxies in the local volume is irrespective of their morphological indices. The more massive (MV0< -13.7) galaxies evolve through self-enrichment and harbor dynamically less evolved younger GCs, whereas fainter galaxies (MV0> - 13.7) are influenced by their environment in the star formation process.
