Radio sources in giant E and S0 galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 1986
Un echantillon de 67 galaxies E et SO a ete observe a l'aide de radiotelescopes de grande sensibilite. On confirme les correlations entre l'emission radio et le type de la galaxie, et entre l'emission radio et l ...

JWST Reveals Powerful Feedback from Radio Jets in a Massive Galaxy at z = 4.1

The Astrophysical Journal
We report observations of a powerful ionized gas outflow in the z = 4.1 luminous radio galaxy TNJ1338-1942 hosting an obscured quasar using the Near Infrared Spectrograph (NIRSpec) on board JWST.

Unveiling New Giant Radio Quasars from the TGSS Sky and Their Large-scale Environment

The Astrophysical Journal Supplement Series
Giant radio quasars (GRQs) are radiatively efficient radio-loud active galactic nuclei that propel large-scale radio jets with projected lengths of more than 0.7 Mpc. We report the discovery of 53 new GRQs within a redshift range of 0.14–2.38, as well as

Radio astronomy and the giant metre-wave radio telescope

, 2017
The cosmos is strange and beautiful, full of unanticipated objects. The only way to understand it is to observe it – in as many different ways as possible.

Origin and Evolution of Large-scale Magnetic Fields [PDF]

, 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.

Cosmic ray contributions from rapidly rotating stellar mass black holes: cosmic Ray GeV to EeV proton and anti-proton sources

Frontiers in Astronomy and Space Sciences
In Radio Super Novae (RSNe) a magnetic field of (B × r) = 1016.0±0.12 Gauss × cm is observed; these are the same numbers for Blue Super Giant (BSG) star explosions as for Red Super Giant (RSG) star explosions, despite their very different wind properties.
