Dynamics of powerful radio galaxies

RJ Turner, SS Shabala - Galaxies, 2023 - mdpi.com
Analytical models describing the dynamics of lobed radio sources are essential for
interpretation of the tens of millions of radio sources that will be observed by the Square …

Simulating the enrichment of fossil radio electrons by multiple radio galaxies

F Vazza, D Wittor, M Brüggen, G Brunetti - Galaxies, 2023 - mdpi.com
We simulate the evolution of relativistic electrons injected into the intracluster medium by five
radio galaxies. We study the spatial transport and the emission properties of the injected …

radiosed – I. Bayesian inference of radio SEDs from inhomogeneous surveys

EF Kerrison, JR Allison, VA Moss… - Monthly Notices of …, 2024 - academic.oup.com
We present here radiosed, a Bayesian inference framework tailored to modelling and
classifying broad-band radio spectral energy distributions (SEDs) using only data from …

Shocks, clouds, and atomic outflows in active galactic nuclei hosting relativistic jets

M Perucho - Astronomy & Astrophysics, 2024 - aanda.org
Context. A number of observations have revealed atomic and/or molecular lines in active
galaxies hosting jets and outflows. Line widths indicate outward motions of hundreds to a …

Annihilation of positrons from AGN jets as a possible source of cosmic gamma-ray background at energies below 511 keV

BA Nizamov, MS Pshirkov - Astronomy Letters, 2024 - Springer
The origin of the diffuse gamma-ray background in the range from hundreds keV to several
MeV is not known conclusively. From current models and observations it is believed that, at …

Spectral signatures of young radio galaxies

SA Young, RJ Turner, SS Shabala… - arXiv preprint arXiv …, 2024 - arxiv.org
We investigate the evolution of active galactic nucleus jets on kiloparsec-scales due to their
interaction with the clumpy interstellar medium (ISM) of the host galaxy and, subsequently …

Giant radio galaxies in the LOFAR deep fields

M Simonte, H Andernach, M Brüggen, GK Miley… - Astronomy & …, 2024 - aanda.org
Context. The reason why some radio galaxies (RGs) grow to form so-called giant radio
galaxies (GRGs) with sizes> 700 kpc, is still unknown. Aims. In this study, we compare the …

A Jet-Induced Shock in a Young, Powerful Radio Galaxy at z= 3.00

N Seymour, JW Broderick, G Noirot, RJ Turner… - arXiv preprint arXiv …, 2024 - arxiv.org
The bright radio source, GLEAM J091734-001243 (hereafter GLEAM J0917-0012), was
previously selected as a candidate ultra-high redshift (z> 5) radio galaxy due to its compact …

AGN energetics and lifetimes from remnant radio galaxies

B Quici, RJ Turner, N Seymour… - arXiv preprint arXiv …, 2024 - arxiv.org
The energy coupling efficiency of active galactic nucleus (AGN) outbursts is known to differ
significantly with factors including the jet kinetic power, duration of the outburst, and …
