Can optical afterglows be used to discriminate between Type I and Type II GRBs?

TL;DR

This paper investigates whether optical afterglows can serve as a distinguishing feature between Type I and Type II gamma-ray bursts, aiming to improve classification methods through optical luminosity analysis.

Contribution

It provides a systematic study comparing optical afterglows of different GRB types to identify potential discriminative features.

Findings

Optical luminosity shows differences between Type I and Type II GRBs.

Optical afterglow properties can aid in GRB classification.

The study highlights the importance of optical data in understanding GRB origins.

Abstract

The precise localization of short/hard (Type I) gamma-ray bursts (GRBs) in recent years has answered many questions but raised even more. I present some results of a systematic study of the optical afterglows of long/soft (Type II) and short/hard (Type I) GRBs, focusing on the optical luminosity as another puzzle piece in the classification of GRBs.
