The intriguing observations of the Swift/Burst Alert Telescope (BAT) X-ray flash (XRF) 060218 and the BATSE-BeppoSAX gamma-ray burst GRB 980425, both with much lower luminosity and redshift compared to other observed bursts, naturally lead to the question of how these low-luminosity (LL) bursts are related to high-luminosity (HL) bursts. Incorporating the constraints from both the flux-limited samples observed with Compton Gamma-ray Observatory (CGRO )/BATSE and Swift/BAT and the redshift-known… Expand

Low-Luminosity Gamma-Ray Bursts as a Distinct GRB Population:A Monte Carlo Analysis
The intriguing observations of Swift/BAT GRB 060218 and CGRO/BATSE burst 980425, both with much lower luminosity and redshift compared to other observed bursts, lead naturally to the question whetherExpand
Using the sample of long gamma-ray bursts (GRBs) detected by Swift-BAT before 2007 June, we measure the cumulative distribution of the peak photon fluxes (log N-log P) of the Swift bursts. ComparedExpand
The origin and progenitors of short-hard gamma-ray bursts (GRBs) remain a puzzle and a highly debated topic. Recent Swift observations suggest that these GRBs may be related to catastrophicExpand

The new and extreme population of gamma-ray bursts (GRBs) detected by the Fermi Large Area Telescope (LAT) shows several new features in high-energy gamma rays that are providing interesting andExpand
Simulations on high-z long gamma-ray burst rate
Since the launch of Swift satellite, the detections of high-z (z > 4) long gamma-ray bursts (LGRBs) have been rapidly growing, even approaching the very early Universe (the record holder currently isExpand
Gamma-ray burst rate: high-redshift excess and its possible origins
Prompted by various analyses of long (type II) gamma-ray burst (GRB) rates and their relationship to the cosmic star formation history, metallicity and luminosity function evolution, weExpand
Nearby low-luminosity GRBs as the sources of ultra-high energy cosmic rays revisited
Low-luminosity gamma-ray bursts (GRBs) with luminosity . 10^49erg/s probably consititute a distinct population from the classic high-luminosity GRBs. They are the most luminous objects detected soExpand

Low-Luminosity Gamma-Ray Bursts as a Unique Population: Luminosity Function, Local Rate, and Beaming Factor
Swift BAT has detected ~200 long-duration GRBs, with redshift measurements for ~50 of them. We derive the luminosity function (?HL) and the local event rate (?) of the conventional high-luminosityExpand
The redshift distribution of Swift gamma‐ray bursts: evidence for evolution
We predict the redshift distribution of long gamma-ray bursts (GRBs) with Monte Carlo simulations. Our improved analysis constrains free parameters with three kinds of observation: (i) the log N -Expand
On the Association of Gamma-Ray Bursts with Massive Stars: Implications for Number Counts and Lensing Statistics
Recent evidence appears to link gamma-ray bursts (GRBs) to star-forming regions in galaxies at cosmological distances. If short-lived massive stars are the progenitors of GRBs, the rate of events perExpand
Luminosity function of gamma-ray bursts derived without benefit of redshifts
We show that the Euclidean value of for gamma-ray bursts (GRBs) selected on a timescale of 1024 ms is correlated with spectral hardness. The value of ranges from ~0.42 for soft bursts to ~0.26 forExpand
On the Redshift Distribution of Gamma-Ray Bursts in the Swift Era
A simple physical model for long-duration gamma-ray bursts (GRBs) is used to fit the redshift (z) and the jet opening angle distributions measured with earlier GRB missions and with Swift. The effectExpand
A short γ-ray burst apparently associated with an elliptical galaxy at redshift z = 0.225
Gamma-ray bursts (GRBs) come in two classes: long (> 2 s), soft-spectrum bursts and short, hard events. Most progress has been made on understanding the long GRBs, which are typically observed atExpand
On the Rates of Gamma-Ray Bursts and Type Ib/c Supernovae
We measure the local rates of "low-luminosity" gamma-ray bursts (LL GRBs; i.e., L 1049 ergs s-1) and "high-luminosity" gamma-ray bursts (HL GRBs). The values are in the range 0 = 100-1800 Gpc-3 yr-1Expand
