“…GRB 000911.-This was a long-lasting burst with a duration of $500 s (Hurley et al 2000;Price et al 2002b). The optical afterglow was observed in detail by Price et al (2002b) and Lazzati et al (2001b).…”

We systematically reanalyzed all gamma-ray burst (GRB) afterglow data published through the end of 2002 in an attempt to detect the predicted supernova light component and to gain statistical insight into its phenomenological properties. We fit the observed photometric light curves as the sum of an afterglow, an underlying host galaxy, and a supernova component. The latter is modeled using published multicolor light curves of SN 1998bw as a template. The total sample of afterglows with established redshifts contains 21 bursts (GRB 970228-GRB 021211). For nine of these GRBs a weak supernova excess (scaled to SN 1998bw) was found, which is what makes this one of the first samples of high-z core-collapse supernovae. Among this sample are all bursts with redshifts less than $0.7. These results strongly support the notion that in fact all afterglows of longduration GRBs contain light from an associated supernova. A statistics of the physical parameters of these GRBsupernovae shows that SN 1998bw was at the bright end of its class, while it was not special with respect to its light-curve shape. Finally, we have searched for a potential correlation of the supernova luminosities with the properties of the corresponding bursts and optical afterglows, but we have not found such a relation.

“…Subsequent observations with RossiXTE led to the discovery of pulsations with P=7.5 s andṖ=8×10 −11 s s −1 (Kouveliotou et al 1998). Possible associations of SGR 1806−20 with the variable non-thermal core of a putative radio supernova remnant (Frail et al 1997) and with a luminous blue variable star (van Kerkwijk et al 1995) were disproved when a more precise localization of the SGR could be obtained with the Interplanetary Network (Hurley et al 1999b) and later improved with Chandra (Kaplan et al 2002). The transient radio source observed with the VLA after the December 2004 giant flare (Cameron et al 2005) led to an even smaller error region and, thanks to the superb angular resolution (FWHM ∼0.1 ′′ ) available with adaptive optics at the ESO Very Large Telescope a variable near IR counterpart (K s =19.3-20), could be identified , the first one for an SGR.…”

Abstract. We present the sample of gamma-ray bursts detected with the anti-coincidence shield ACS of the spectrometer SPI on-board INTEGRAL for the first 26.5 months of mission operation (up to Jan. 2005). SPI-ACS works as a nearly omnidirectional gamma-ray burst detector above ∼80 keV but lacks spatial and spectral information. In this catalogue, the properties derived from the 50 ms light curves (e.g., T 90 , C max , C int , variability, V/V max ) are given for each candidate burst in the sample. A strong excess of very short events with durations <0.25 s is found. This population is shown to be significantly different from the short-and long-duration burst sample by means of the intensity distribution and V/V max test and is certainly connected with cosmic ray hits in the detector. A rate of 0.3 true gamma-ray bursts per day is observed.
