Supernovae Distribution and Host Galaxy Properties

TL;DR

This study analyzes the spatial distribution of supernovae in SDSS host galaxies to understand progenitor origins and galaxy structure, filling a gap in 3D distribution research.

Contribution

It provides the first comprehensive analysis of 3D supernova distributions and their relation to host galaxy properties using SDSS data.

Findings

Supernovae are distributed differently in galaxy disks and halos.

Progenitor types correlate with specific galaxy structural features.

The study offers new insights into supernova progenitor environments.

Abstract

We present the summary of our last results on the spatial distribution and relative frequencies of Supernovae (SNe) in a large number of host galaxies from the Sloan Digital Sky Survey (SDSS). We use the locations of SNe in order to study the relations between radial/azimuthal distributions of SNe and properties of their hosts and environments. On the other hand, the vertical distribution of SNe allows to study the progenitors association to the thin or thick discs, and to the stellar halo. We also propose the underlying mechanisms shaping the number ratios of SNe types. It is important to note that there were no extended studies of the 3D distribution of SNe and structural parameters of hosts. Our study is intended to fill this gap and better constrain the nature of SN progenitors.
