Observations of the radio jets in NGC 5090 (PKS B1318 — 434)

We present results from Australia Telescope Compact Array (ATCA) observations, at 4.796 and 8.640 GHz, of the Fanaroff-Riley class I, extragalactic radio jets in the galaxy NGC 5090 (pKS B1318—434). This radio galaxy is relatively close, z = 0.011, and may be evolving under the influence of a nearby...

Description
Summary:We present results from Australia Telescope Compact Array (ATCA) observations, at 4.796 and 8.640 GHz, of the Fanaroff-Riley class I, extragalactic radio jets in the galaxy NGC 5090 (pKS B1318—434). This radio galaxy is relatively close, z = 0.011, and may be evolving under the influence of a nearby galaxy, NGC 5091. Total intensity and polarization radio images of these jets are used to determine the magnetic field structure, fractional polarization, spectral index and depolarization variations along the jets. Mach numbers of 1–3 and velocities of 2000–15 000 km s−1 along the jets are implied, with velocities of 0.05–0.2 times the speed of light where the jets initially flare.
