Project Abstract
Supernovae are massive explosions in the universe that occur when a star collapses in its core due to the immense pressure of its gravity. These explosions are divided into Type I and Type II supernovae based upon their progenitors. In this study, we examine over 20,000 supernovae from multiple catalogues to determine their rate of occurrence in different galaxies. We investigated each type of supernova in relation to its redshift and distance from the center of the galaxy. Our findings reveal an abundance of supernovae in the lower redshift and the opposite in case of a higher redshift. This is shown in our frequency distribution graphs portraying a gradual decrease in the number of supernovae with an increase in redshift. The same results are also seen where higher numbers of supernovae are occurring at lower distances. We did further analysis by generating frequency distribution figures for supernova types in different classifications of galaxies. The results show a widespread appearance of Type Ia supernovae in almost all types of galaxies, including elliptical and lenticular, indicating the presence of neutron stars. By contrast, a sparse population of Type Ib and Ic supernovae are found in the elliptical and Irregular galaxies with its frequency rate diminishing when distance is greater than 25 mpc. A common resemblance from these distributions shows an increasing peak in the range 10 mpc < distance < 25 mpc, indicating a higher population I stars in the disk of the galaxy.
