The redshift distribution of GRBs
Dafne Guetta
ORT Braude, Carmiel, Israel
Long gamma ray bursts (GRBs) are associated to the death of massive stars and have been discovered, so far, up to z = 8.
Therefore, they hold the promise of probing star-formation and metal enrichment up to very high redshifts. However, the present
GRB samples with redshift determinations are largely incomplete, and therefore a careful analysis of selection effects plaguing these
samples is mandatory before any conclusion can be drawn from the observed GRB redshift distribution.
In this talk I will discuss some ideas to take into account these effects.
