The cosmic build-up of dust and metals : Accurate abundances from GRB-selected star-forming galaxies at 1.7 < z < 6.3
(2023-11-15)
The chemical enrichment of dust and metals in the interstellar medium of galaxies throughout cosmic time is one of the key driving processes of galaxy evolution. Here we study the evolution of the gas-phase metallicities, ...
Numerical modelling of the lobes of radio galaxies – Paper V: universal pressure profile cluster atmospheres
(2023-09-26)
We present relativistic magnetohydrodynamic modelling of jets running into hydrostatic, spherically symmetric cluster atmospheres. For the first time in a numerical simulation, we present model cluster atmospheres based ...
Cosmic evolution of radio-AGN feedback: confronting models with data
(2023-08-30)
Radio-mode feedback is a key ingredient in galaxy formation and evolution models, required to reproduce the observed properties of massive galaxies in the local Universe. We study the cosmic evolution of radio-active ...
A low frequency sub-arcsecond view of powerful radio galaxies in rich-cluster environments: 3C 34 and 3C 320
(2023-04-30)
Models of radio galaxy physics have been primarily based on high frequency ($\geqslant$1 GHz) observations of their jets, hotspots, and lobes. Without highly resolved low frequency observations, which provide information ...
CosmoDRAGoN simulations -- I. Dynamics and observable signatures of radio jets in cosmological environments
(2023-04-12)
We present the Cosmological Double Radio Active Galactic Nuclei (CosmoDRAGoN) project: a large suite of simulated AGN jets in cosmological environments. These environments sample the intra-cluster media of galaxy clusters ...
The hot gas distribution, X-ray luminosity and baryon budget in the L-Galaxies semi-analytic model of galaxy formation
(2023-03-31)
Hot ionized gas is important in the baryon cycle of galaxies and contributes the majority of their ``missing baryons''. Until now, most semi-analytic models of galaxy formation have paid little attention to hot gaseous ...
Galactic Population Synthesis of Radioactive Nucleosynthesis Ejecta
(2023-03-30)
Diffuse gamma-ray line emission traces freshly produced radioisotopes in the interstellar gas, providing a unique perspective on the entire Galactic cycle of matter from nucleosynthesis in massive stars to their ejection ...
New mechanisms for forming multiple hotspots in radio jets
(2023-03-06)
Hotspots of radio galaxies are regions of shock-driven particle acceleration. Multiple hotspots have long been identified as potential indicators of jet movement or precession. Two frequent explanations describe a secondary ...
GRB 160410a: The first chemical study of the interstellar medium of a short GRB
(2023-03-01)
Short gamma-ray bursts (SGRBs) are produced by the coalescence of compact binary systems which are remnants of massive stars. GRB 160410A is classified as a short-duration GRB with extended emission and is currently the ...
Chemo-Dynamical Evolution of Galaxies
(Springer Nature, 2023-02-17)
Stars are fossils that retain the history of their host galaxies. Elements heavier than helium are created inside stars and are ejected when they die. From the spatial distribution of elements in galaxies, it is therefore ...
