  Precessing Gamma Jets, originated by Neutron Stars or Black Holes, may blaze
to the observer leading to Gamma Bursts (GRBs) and Soft Gamma repeaters (SGRs).
The thin gamma jet is born either at Supernova (SN) like events mostly at the
cosmological distances, like GRB, or at nearer accreting binary system, like
SGRs. The collimated gamma jet Comptonized by the ultrarelativistic inner
electron pairs jets (hitting thermal photos) spins (because of the pulsar) and
precedes (because of a companion or accreating disk) in helical and spiral
nebular shapes. Its cumulative spray may eject and sweep gas creating nebular
rings and plerions and, after long time, partiall HI supershells. Their
consequent gravitational fragmentation may lead to characteristic star
formation in giant arcs, which might be just the relic imprints of the earliest
peaked GRBs and the late steady SGRs precesing jet emissions. Relic stellar
rings and arcs may inform, by present morphology on the jet binary eccentricity
and its time evolution. Their lifetime and occurrence may probe the
Supernova-GRB connection.
