Concluding Remarks

As every year, the speaker presenting the concluding remarks has the problem of the wealth of too many interesting presentations. It is not easy to select just a few topics among many fascinating ones and any choice will be, necessarily, arbitrary. This year, I decided to make brief comments on astrophysical neutrinos, on cosmology and on gamma-ray bursts. My personal nomination for the hits of the conference goes this year to the giant flare of SGR 1806–20 (27.12.2004), which threw a new light not only on magnetars, but possibly also on a certain class of short gamma-ray bursts and to GRB 050509b − possibly the first short gamma-ray burst with a measured distance.
