    Abstract

    The optical afterglows of the gamma-ray bursts can be strongly polarized, in principle up to tens of percents, if (1) the afterglow is synchrotron radiation from an ultrarelativistic blast, (2) the blast is beamed during the afterglow phase, i.e., the shock propagates within a narrow jet, (3) we observe at the right time from the right viewing angle, and (4) magnetic fields parallel and perpendicular to the jet have different proper strengths.
