The statistical investigation of type Ib/c and II supernovae and their host galaxies

TL;DR

This study uses statistical methods to analyze the spatial distribution of type Ib/c and II supernovae within their host galaxies, revealing that Ib/c supernovae are more centrally concentrated, especially in active galaxies.

Contribution

It provides a detailed statistical comparison of supernova types and their host galaxy properties, highlighting differences in their radial distributions within galaxies.

Findings

Type Ib/c supernovae are more concentrated toward galaxy centers than type II.

Supernovae in active galaxies are more centrally located than in normal galaxies.

The concentration effect is stronger for type Ib/c supernovae.

Abstract

This is a statistical study of the properties of type Ib/c and II supernovae and of the integral parameters of their spiral host galaxies. The methods of one-dimensional and multivariate statistics were applied to the data sample. It was found that the Ib/c supernovae are more concentrated radially toward the centers of the galaxies than those of type II. The distributions of the radial distances R(SN)/R(25) for the type Ib/c and II supernovae in active galaxies are more concentrated toward the center than in normal galaxies. This effect is stronger for type Ib/c than for type II supernovae.
