Radio jets and galaxies as cosmic string probes [PDF]

Frontiers of Physics, 2011
The lensing effect of a cosmic string is studied, and some new methods are proposed to detect the cosmic string. The technique for using jets as extended gravitational lensing probes was firstly explored by Kronberg. We use the "alignment-breaking parameter" $ _G $ as a sensitive indicator of gravitational distortion by a wiggly cosmic string.

Bent jets in high-redshift galaxies

The Astrophysical Journal, 1984
On montre que la courbure des jets radio des galaxies a forts decalages spectraux est une consequence naturelle de la plus grande densite du gaz dans les galaxies elliptiques dans le passe et de la stabilite ou de l'instabilite des orbites particulieres dans un potentiel triaxial.

Face‐on Dust Disks in Galaxies with Optical Jets

The Astrophysical Journal, 2000
The presence of optical synchrotron jets in radio galaxies is relatively rare. Here, we show that of the nearest five FR-I 3CR radio galaxies showing optical jets, {\it four} show evidence for almost circular, presumably face-on, dust disks. This is strong support for the two-fold idea that (\romannumeral1) jets emerge close to perpendicular to inner ...

Jetted subgalactic-size radio sources in merging galaxies

Astronomy & Astrophysics
Context. The long-standing question concerning jetted subgalactic-size (JSS) radio sources is whether they will evolve into large radio galaxies, die before escaping the host galaxy, or remain indefinitely confined to their compact size. Aims. Our main goal is to propose a scenario that explains the relative number of JSS radio sources and their ...
