Energetics and Luminosity Function of Gamma-ray Bursts

Gamma-ray bursts are believed to be some catastrophic event in which material is ejected at a relativistic velocity, and internal collisions within this ejecta produce the observed γ-ray flash. The angular size of a causally connected region within a relativistic flow is of the order the angular width of the relativistic beaming, γ. Thus, different observers along different lines of sights coul...

On the Kinematic Origin of the Luminosity-Pulse Lag Relationship in Gamma-ray Bursts

This paper presents an interpretation based on gamma-ray burst source kinematics for the relationship found by Norris et al. between peak luminosity and energy-dependent pulse lag. I argue that the correlation should instead be between number luminosity and pulse lag. This interpretation improves the least-squares fit of this correlation for the known bursts by 25 percent or more. It also sugge...

Low Luminosity Gamma-ray Bursts as a Unique Population: Luminosity Function, Local Rate, and Beaming Factor

The newly discovered GRB 060218 is a nearby event with low luminosity, resembling GRBs 980425 and 031203. The fact that it was discovered by Swift slightly over 1-year operation suggests that the GRB rate of these low luminosity GRBs (LL-GRBs) should be much higher than previous expected, and that they form a distinct new class of GRBs with respect to the conventional high luminosity GRBs (HL-G...

The Decline of the Source Population of Gamma-ray Bursts and Their Luminosity Function

The source population of gamma-ray bursts (GRBs) declines towards the present epoch being consistent with the measured decline of the star formation rate. We show this using the brightness distribution of 3255 long BATSE GRBs found in an off-line scan of the BATSE continuous 1.024 s count rate records. The significance of this conclusion is enhanced by the detection of three GRBs with known red...

Quantifying the Luminosity Evolution in Gamma-ray Bursts

We estimate the luminosity evolution and formation rate for over 900 GRBs by using redshift and luminosity data calculated by Band, Norris, & Bonnell (2004) via the lag-luminosity correlation. By applying maximum likelihood techniques, we are able to infer the true distribution of the parent GRB population’s luminosity function and density distributions in a way that accounts for detector selec...
