Are all Gamma Ray Bursts like GRB 980425, GRB 030329 and GRB 031203?
Dafne Guetta, Rosalba Perna, Luigi Stella +1
We study the probability that three GRBs (980425, 030329, 031203) are found within z=0.17, given the luminosity functions consistent with the log N-log S relationship for classical…
The Luminosity and Redshift Distributions of Short-Duration GRB
Dafne Guetta, Tsvi Piran
Using the BATSE peak flux distribution we rederive the short GRBs luminosity function and compare it with the observed redshift distribution of long bursts. We show that both distr…
Constraining the Structure of GRB Jets Through the log(N)-log(S) Distribution
Dafne Guetta, Jonathan Granot, Mitchell C. Begelman
A general formalism is developed for calculating the luminosity function and the expected number of observed GRBs above a peak photon flux for any GRB jet structure. This n…
Internal shocks and the blazar sequence. Low and intermediate power BL Lac objects
Dafne Guetta, Gabriele Ghisellini, Davide Lazzati +1
We consider internal shocks as the main dissipation mechanism responsible for the emission in blazars and show that it can satisfactorily account for the properties of all blazars.…
