We present comprehensive multiwavelength observations of three gamma-ray bursts (GRBs) with durations of several thousand seconds. We demonstrate that these events are extragalactic transients; in particular, we resolve the long-standing conundrum of the distance of GRB 101225A (the "Christmas-day burst"), finding it to have a redshift z = 0.847 and showing that two apparently similar events (GRB 111209A and GRB 121027A) lie at z = 0.677 and z = 1.773, respectively. The systems show extremely… Expand
Are Ultra-long Gamma-Ray Bursts Different?
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
HOW LONG DOES A BURST BURST
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,Expand
A very luminous magnetar-powered supernova associated with an ultra-long γ-ray burst
TLDR
It is reported that a supernova was associated with the ultra-long-duration γ-ray burst GRB 111209A, at a redshift z of 0.677, and this supernova is more than three times more luminous than type Ic supernovae associated with long-duration μ-ray bursts, and its spectrum is distinctly different.

THE ULTRA-LONG GRB 111209A. II. PROMPT TO AFTERGLOW AND AFTERGLOW PROPERTIES
The ultra-long gamma-ray burst GRB 111209A at redshift z = 0.677 is the longest GRB ever observed thus far, with a rest frame prompt emission duration of ~4 hr. In order to explain the burstExpand
Are Ultra Long Gamma Ray Bursts powered by black holes spinning down
Gamma-ray bursts (GRBs) are violent explosions, coming from cosmological distances. They are detected in gamma-rays (also X-rays, UV, optical, radio) almost every day, and have typical durations of aExpand

TLDR
Some of the milestones made in GRB research during the Swift era are summarized, and how previous widely accepted theoretical models have had to adapt to accommodate the new wealth of observational data are summarized. Expand
Study of a Population of Gamma-ray Bursts with Low-Luminosity Afterglows
Gamma-ray bursts (GRB) are extreme events. They are crudely classified into two groups based on their duration, namely the short and long bursts. Such a classification has proven to be useful toExpand
Special gamma-ray bursts and special radiation components from gamma-ray bursts
Gamma-ray bursts (GRBs) were first detected in 1960s. Since then, GRBs have been observed extensively in gamma-rays. The afterglows of several hundred GRBs were also detected, providing us withExpand

Abstract Our understanding of gamma-ray bursts (GRBs) has come a long way in the past fifty years since their first detection. We now know that GRBs arise in distant galaxies and that there are atExpand
Can we quickly flag ultra-long gamma-ray bursts?
Ultra-long gamma-ray bursts are a class of high-energy transients lasting several hours. Their exact nature is still elusive, and several models have been proposed to explain them. Because of theExpand

The ultra-long Gamma-Ray Burst 111209A: the collapse of a blue supergiant?
We present optical, X-ray and gamma-ray observations of GRB 111209A, at a redshift of z = 0.677. We show that this event was active in its prompt phase for about 25000 seconds, making it the longestExpand
GRB 091024A AND THE NATURE OF ULTRA-LONG GAMMA-RAY BURSTS
We present a broadband study of gamma-ray burst (GRB) 091024A within the context of other ultra-long-duration GRBs. An unusually long burst detected by Konus-Wind (KW), Swift, and Fermi, GRB 091024AExpand
The Bright Gamma-Ray Burst of 2000 February 10: A Case Study of an Optically Dark Gamma-Ray Burst
The gamma-ray burst GRB 000210 had the highest gamma-ray peak flux of any event localized by BeppoSAX as yet, but it did not have a detected optical afterglow, despite prompt and deep searches downExpand
How common are long gamma-ray bursts in the local Universe?
TLDR
The results show correlation of the entire long GRB sample to remain consistent with zero out to the highest radii considered whereas a sub-sample selected to be low fluence, spectrally soft, with smooth single-peaked light curves demonstrates increased correlation with galaxies within � 155 Mpc.

A very energetic supernova associated with the γ-ray burst of 29 March 2003
Over the past five years evidence has mounted that long-duration (>2 s) γ-ray bursts (GRBs)—the most luminous of all astronomical explosions—signal the collapse of massive stars in our Universe. ThisExpand
No supernovae associated with two long-duration γ-ray bursts
It is now accepted that long-duration γ-ray bursts (GRBs) are produced during the collapse of a massive star1,2. The standard ‘collapsar’ model3 predicts that a broad-lined and luminous type IcExpand
The Early X-Ray Emission from GRBs
TLDR
Observations of the early X-ray emission for a sample of 40 gamma-ray bursts obtained using the Swift satellite, for which the narrow-field instruments were pointed at the burst within 10 minutes of the trigger, show that theX-ray light curve can be well described by an exponential that relaxes into a power law.

A Mean Redshift of 2.8 for Swift gamma - ray bursts

The high mean redshift of GRBs and their wide redshift range clearly demonstrates their suitability as efficient probes of galaxies and the intergalactic medium over a significant fraction of the history of the Universe. Expand
A novel explosive process is required for the γ-ray burst GRB 060614

Swift multi-wavelength observations of the bright flaring burst GRB 051117A
TLDR
The superb quality of the early X-ray light-curve and spectra of this source, one of the brightest seen by the X-rays Telescope at such early times, allows an unprecedented look at the spectral and temporal evolution of the prompt and early afterglow emission for this GRB and allows us to place stringent limits on the detection of lines.
