Distributions of Peak Flux and Duration for Gamma-ray Bursts
Many of the important conclusions about Gamma-Ray Bursts follow from the distributions of various quantities such as peak ux or duration. We show that for astrophysical transients such as bursts, multiple selection thresholds can lead to various forms of data truncation, which can strongly aaect the distributions obtained from the data if not accounted for properly. Thus the data should be cons...
متن کاملDuration Distributions of Bright and Dim Batse Gamma-ray Bursts
We have measured the T90 and T50 durations of bright and dim gamma-ray bursts (GRBs) detected by the Compton Gamma Ray Observatory’s Burst and Transient Source Experiment (BATSE). The T90 (T50) duration is defined as the interval over which 5% (25%) to 95% (75%) of the burst counts accumulate. Out of 775 bursts observed by BATSE, 159 bursts were analyzed; bursts with durations shorter than 1.5 ...
متن کاملShort-Duration Gamma-Ray Bursts
Gamma-ray bursts (GRBs) display a bimodal duration distribution, with a separation between the shortand long-duration bursts at about 2 sec. The progenitors of long GRBs have been identified as massive stars based on their association with Type Ic core-collapse supernovae, their exclusive location in starforming galaxies, and their strong correlation with bright ultraviolet regions within their...
متن کاملIntensity Distributions of Gamma-Ray Bursts
Observations of individual bursts chosen by the vagaries of telescope availability demonstrated that bursts are not standard candles and that their apparent energy can be as great as 10 erg. However, determining the distribution of their apparent energy (and of other burst properties) requires the statistical analysis of a well-defined burst sample; the sample definition includes the threshold ...
متن کاملObservational Prospects for Afterglows of Short Duration Gamma-ray Bursts
If the efficiency for producing γ-rays is the same in short duration (<∼ 2 s) Gamma-Ray Bursts (GRBs) as in long duration GRBs, then the average kinetic energy of short GRBs must be ∼ 20 times less than that of long GRBs. Assuming further that the relativistic shocks in short and long duration GRBs have similar parameters, we show that the afterglows of short GRBs will be on average 10–40 times...
