GalaxiesI demonstrate the usage of planetary nebulae (PNe) to infer that a pair of jets shaped the ejecta of the core-collapse supernova (CCSN) SN 1987A. The main structure of the SN 1987A inner ejecta, the ‘keyhole’, comprises two low-intensity zones.

The Astrophysical JournalHow a seemingly “dead” host galaxy provides fuel for its active galactic nucleus (AGN) remains an unresolved problem. Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we present a new high-sensitivity atomic-hydrogen (H i ...

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.

The Astrophysical JournalWinds and jets are symbiotic when the accretion rate is low, according to black hole accretion theory. Both components are potentially important for active galactic nucleus (AGN) feedback, but previous works typically include only jets with free ...

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 ...
