نویسنده
چکیده
An examination of the positions and redshifts of the compact, QSO-like objects reported near the Seyfert 2 galaxy NGC 1068 has revealed many relationships that suggest strongly that the objects have been ejected from the galaxy. Although some of the same relations have been found for the compact objects near NGC 3516, the higher number of sources near NGC 1068 has resulted in a detailed physical model. The results indicate that the objects have been expelled in at least four similarly structured ejection events from a point near the centre of NGC 1068 within the last 6×10 6 yrs and with very modest velocities [l-o-s components ∼ (1 − 2) × 10 4 km s −1 ]. From the age and rotation angle of successive events, the rotation period of the central object is calculated to be ∼ 10 7 yrs, in good agreement with the nuclear rotation period obtained from kinematic studies of NGC 1068. The large redshifts of the objects cannot be explained by their modest ejection velocities and require an additional, large intrinsic component.

We report the first direct observational evidence for alignment of galaxy spin axes with the local tidal shear field. We measured quantitatively the strength of this directional correlation of disk galaxies in the Tully catalog with the local shear field reconstructed from PSCz galaxies. The observed correlation of galaxy spin orientations with the intrinsic shear field is found to be significa...
