Two Dimensional Clustering of Swift/BAT and Fermi/GBM Gamma-ray Bursts
Studies of Gamma-ray Burst (GRB) properties, such as duration and spectral hardness, have found evidence for additional classes beyond the short-hard (merger) and long-soft (collapsar) prototypes.Several clustering analyses of the duration-hardness plane identified a third, intermediate duration, class.In this work, Gaussian Mixture Model-based (GM
