Scientific paper

INTEGRAL has proven to be an excellent mission for the study of bursts, with speed, accuracy, and sensitivity rivalling those of Swift. Gamma-ray bursts are detected both within the IBIS field of view at a rate of about 10/year, and by the SPI anticoincidence system at a rate of about 100/year, as well as by the SPI. Hundreds of SGR bursts have been detected from SGR1806-20 by IBIS during Galactic center observations and ToO pointings. I will review some of the highlights of these observations, which include the closest securely identified GRB (z=0.105) after 980425/SN1998bw, and the discovery of a hardness-intensity anticorrelation for SGR bursts. I will also mention some of the more exotic possibilities offered by INTEGRAL, such as the measurement of GRB polarization and the study of quantum gravity using bursts.
