| dc.description | Damped oscillating afterglows in GRB 030329 and in SGR 1900+14 find a natural explanation in precessing gamma Jet model for both GRBs and SGRs. The very thin Jet cone (solid angle ratio Delta Omega/Omega less or near 10^{-8}) combines at once the Supernova power and the apparent huge GRBs output: {dE/dt}_{GRBs} comparable to {dE/dt}_{SN}* Omega/(Delta Omega), leading to a better understanding of their remarkable GRB-Super Nova connection shown in early GRB980425/SN1998bw event and in most recent GRB030329/SN2003dh one. The same thin beaming offer a understanding of the apparent SGR-X-Pulsar power connection: {dE/dt}_{SGRs} comparable to {dE/dt}_{Xpuls}*Omega/(Delta Omega). The precessing Jet model for both GRBs and SGRs, at their different luminosity,explains the existence of a few identical energy spectra and time evolution of these two sources leading to their unified understanding. The spinning-precessing Jet explains the rare mysterious X-Ray precursors in GRBs and SGRs. The Multi-precessing Jet at peak activity in all band may explain the puzzling X or optical re-brightening bumps found in last GRB030329 and earliest SGR 1900+ 14 on 27 August 1998 and on 18 April 2001, as well as the multi-bump radio light-curve observed in GRB980425 and GRB030329. Rarest micro-quasars in our galaxy as SS433, and Herbig Haro objects describe these thin precessing Jet imprint in their 3D relic nebulae shapes. | |
