Where are the missing gamma ray burst redshifts?
D. M. Coward, D. Guetta, R. R. Burman +1
In the redshift range z = 0-1, the gamma ray burst (GRB) redshift distribution should increase rapidly because of increasing differential volume sizes and strong evolution in the s…
Selection effects shaping the Gamma Ray Burst redshift distributions
F. Fiore, D. Guetta, S. Piranomonte +2
Long Gamma Ray Bursts hold the promise of probing star-formation and metal enrichment up to very high redshifts. The present GRB samples with redshift determination are largely inc…
The exceptionally extended flaring activity in the X-ray afterglow of GRB 050730 observed with Swift and XMM-Newton
M. Perri, D. Guetta, L. A. Antonelli +27
We present the results of a detailed spectral and temporal analysis of Swift and XMM-Newton observations of the high redshift (z=3.969) GRB 050730. The X-ray afterglow of GRB 05073…
Do long-duration GRBs follow star formation?
Dafne Guetta, Tsvi Piran
We compare the luminosity function and rate inferred from the BATSE long bursts peak flux distribution with those inferred from the Swift peak flux distribution. We find that both…
