Jets in Fanaroff-Riley class I radio galaxies

open access: yes, 1997
Presented here are observations, analysis and interpretation of five Fanaroff-Riley class I radio galaxies. Total intensity and polarised emission was observed in each source at 6 and 3 cm at angular resolutions of 16 to 2 arc seconds. These sources have

Radio jets and gamma-ray emission in radio-silent narrow-line Seyfert 1 galaxies

open access: yes, 2018
We have detected six narrow-line Seyfert 1 (NLS1) galaxies at 37 GHz that were previously classified as radio silent and two that were classified as radio quiet.

A new method to classify black hole jets from radio galaxies [PDF]

open access: yes
Galaxies are made up of millions of stars bound together by gravity. Black holes that are 100,000 times heavier than our sun are known as supermassive black holes. Most galaxies, including the Milky Way, contain a supermassive black hole at their centre.

Chandra finds that X-ray jets are common in low-power radio galaxies

open access: yes, 2001
We present results for the first three low-power radio galaxies from the B2 bright sample to have been observed with Chandra. Two have kiloparsec-scale radio jets, and in both Chandra resolves jet X-ray emission, and detects soft X-ray core emission and ...

Origin and Evolution of Large-scale Magnetic Fields

open access: yes, 2015
Magnetic elds are ubiquitous at all scales in the Universe and have been observed in galaxies and clusters of galaxies via observations of di use radio emission and Faraday Rotation Measures.

Acceleration of Ultra-high-energy Cosmic Rays in the Kiloparsec-scale Jets of Nearby Radio Galaxies

open access: yes
Radio galaxies have long been considered as potential sources of ultra-high-energy cosmic rays (UHECRs). Recent analyses of the UHECR spectrum, composition, and arrival directions indicate that the nearest radio galaxy, Centaurus A, could be linked to ...

Jetted subgalactic-size radio sources in merging galaxies

open access: yesAstronomy & 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 ...

The HST survey of the B2 sample of radio galaxies: Detection of two optical jets

open access: yes, 2002
We present HST observations of previously undetected optical jets in the low-luminosity radio galaxies B2 0755+37 and B2 1553+24. We show that there is accurate spatial coincidence between optical and radio emission, implying that the former is likely to
