Several gamma-ray bursts (GRBs) last much longer (∼hours) in γ-rays than typical long GRBs (∼minutes), and it has recently been proposed that these 'ultra-long GRBs' may form a distinct population, probably with a different (e.g., blue supergiant) progenitor than typical GRBs. However, Swift observations suggest that many GRBs have extended central engine activities manifested as flares and internal plateaus in X-rays. We perform a comprehensive study on a large sample of Swift GRBs with X-Ray… Expand

Are Ultra-long Gamma-Ray Bursts Different?
• Physics
• 2013
The discovery of a number of gamma-ray bursts (GRBs) with duration exceeding 1000 s has opened the debate on whether these bursts form a new class of sources, the so-called ultra-long GRBs, or ifExpand
Can we quickly flag ultra-long gamma-ray bursts?
• Physics
• Monthly Notices of the Royal Astronomical Society

Distributions of pseudo-redshifts and durations (observed and intrinsic) of Fermi GRBs
• Physics
• 2018
Ever since the insightful analysis of the durations of gamma-ray bursts (GRBs) by Kouveliotou et al. (Astrophys. J. Lett. 413:101, 1993), GRBs have most often been classified into two populations:Expand
Are Ultra Long Gamma Ray Bursts powered by black holes spinning down

We present the results of a comprehensive study of the luminosity function, energetics, prompt gamma-ray correlations, and classification methodology of short-hard and long-soft GRBs (SGRBs andExpand
Catalogue of isolated emission episodes in gamma-ray bursts from Fermi, Swift and BATSE
• Physics
• 2015
We report a comprehensive catalog of emission episodes within long gamma-ray bursts (GRBs) that are separated by a quiescent period during which gamma-ray emission falls below the background level.Expand
