We have observed 17 sources in a complete sample of FRIs in nearby UGC galaxies with the VLBA at 1.67 GHz. We detect core-jets in 60% and twin-jets in 10%. The data (alignment, sidedness ratios, detection statistics) are consistent with relativistic

The presence of optical synchrotron jets in radio galaxies is relatively unusual. We show that of the nearest five FRI 3CR radio galaxies showing optical jets, four display evidence for almost circular, presumably face-on, dust discs. None of the oth

We have obtained Hubble Space Telescope Space Telescope Imaging Spectrograph long-slit spectroscopy of the aligned emission-line nebulae in three compact steep-spectrum radio sources: 3C 67, 277.1, and 303.1. We find systematic offsets (similar to300

We have carried out 2-D axisymmetric numerical simulations of light, supersonic jets. These simulations are used to test the hypothesis of self-similarity for the propagation of jets in powerful radio galaxies. A large range of jet parameters has bee

We present ASCA SIS and GIS observations of two GHz peaked spectrum (GPS) radio galaxies, PKS 1345 + 125 (4C12.50, z = 0.122) and 2352+495 (z = 0.237). In the energy band 2-10 keV, 1345+125 is detected with about 2 x 10(43) ergs s(-1), while 2352+495

In this paper we present the data from our J-, H-, and K-band imaging program of powerful radio sources. The sample consists of radio galaxies classified as either compact (20 kpc) radio sources. Source images, photometry results, radial profiles, an

By means of KPNO 2.1 m J-, H-, and K-band data on samples of gigahertz peaked spectrum (GPS, radio size 20 kpc), we have constructed mean broadband spectral energy distributions (SEDs) for each of the object classes and compared these with synthetic
