Calibrating hydrogen-rich core-collapse supernovae for their use as distance indicators independently of type Ia supernovae

TL;DR

This paper develops a new method to calibrate hydrogen-rich core-collapse supernovae as distance indicators using photometric data, aiming to provide an alternative to type Ia supernovae for measuring cosmic distances.

Contribution

The study introduces a novel calibration technique for hydrogen-rich CC-SNe based on light curve correlations, independent of prior methods and type Ia supernovae.

Findings

New correlations for supernova calibration based on light curves

Potential for using hydrogen-rich CC-SNe as independent distance indicators

Comparison with previous calibration methods

Abstract

Using our new general-relativistic, radiation hydrodynamics, Lagrangian code, we computed a rather extended grid of hydrogen-rich core-collapse supernova (CC-SN) models and explored the potentials of their "standardization" as distance indicators. We discuss the properties of some calibrations previously reported in the literature and present new correlations based on the behavior of the light curve, that can be employed for calibrating hydrogen-rich CC-SNe using only photometric data.
