Significant gravitational wave emission is expected from gamma-ray burstsarising from compact stellar mergers, and possibly also from bursts associatedwith fast-rotating massive stellar core collapses. These models have in commona high angular rotation rate, and observations provide evidence for jetcollimation of the photon emission, with properties depending on the polarangle, which may also be of relevance for X-ray flashes. Here we consider thegravitational wave emission and its polarization as a function of angle whichis expected from such sources. We discuss possible correlations between theburst photon luminosity, or the delay between gravitational wave bursts andX-ray flashes, and the polarization degree of the gravitational waves.Comment: 10 pages, 1 figure, accepted for publication in ApJ
