Gamma-ray burst X-ray flares are believed to mark the late time activity of the central engine. We compute the temporal evolution of the average flare luminosity hLi in the common rest frame energy band of 44 GRBs taken from the large Swift 5-years data base. Our work highlights the importance of a proper consideration of the threshold of detection of flares against the contemporaneous continuous X-ray emission. In the time interval 30s < t < 1000s we find hLi / t 2.7±0.1 ; this implies that… Expand

X-ray flares in GRBs: general considerations and photospheric origin
Observations of X-ray flares from Gamma Ray Bursts (GRBs) imply strong constraints on possible physical models. We provide a general discussion of these. In particular, we show that in order toExpand
Photosphere Emission in the X-Ray Flares of Swift Gamma-Ray Bursts and Implications for the Fireball Properties
X-ray flares of gamma-ray bursts (GRBs) are usually observed in the soft X-ray range and the spectral coverage is limited. In this paper, we present an analysis of 32 GRB X-ray flares that areExpand

Flares in Gamma Ray Bursts: Disc Fragmentation and Evolution
Flaring activity following gamma-ray bursts (GRBs), observed in both long and short GRBs, signals a long-term activity of the central engine. However, its production mechanism has remained elusive.Expand

X-ray flares and the duration of engine activity in gamma-ray bursts
The detection of bright X-ray flares superimposed on the regular afterglow decay in Swift gamma-ray bursts has triggered theoretical speculations on their origin. We study the temporal properties ofExpand

The First Survey of X-Ray Flares from Gamma-Ray Bursts Observed by Swift: Temporal Properties and Morphology
All evidence indicates that flares are indeed related to the workings of the central engine and originate from internal shocks rather than external shocks, an indication of a common origin for gamma-ray pulses and X-ray flares. Expand
