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 Humidifiers and Nebulizers - Nebulizers duration-hardness plane identified a third, intermediate duration, class.In thi
