Radiative AGN feedback on a moving mesh: the impact of the galactic disc and dust physics on outflow properties
David J. Barnes, Rahul Kannan, Mark Vogelsberger +1
Feedback from accreting supermassive black holes, active galactic nuclei (AGN), is now a cornerstone of galaxy formation models. In this work, we present radiation-hydrodynamic sim…
SPMHD simulations of Structure Formation
David J. Barnes, Alvina Y. L. On, Kinwah Wu +1
The intracluster medium of galaxy clusters is permeated by μG magnetic fields. Observations with current and future facilities have the potential to illuminate the role of these ma…
Early-type galaxy density profiles from IllustrisTNG: I. Galaxy correlations and the impact of baryons
Yunchong Wang, Mark Vogelsberger, Dandan Xu +10
We explore the isothermal total density profiles of early-type galaxies (ETGs) in the IllustrisTNG simulation. For the selected 559 ETGs at with stellar mass $10^{10.7}\mat…
The Cluster-EAGLE project: a comparison of dynamical mass estimators using simulated clusters
Thomas J. Armitage, Scott T. Kay, David J. Barnes +2
Forthcoming large-scale spectroscopic surveys will soon provide data on thousands of galaxy clusters. It is important that the systematics of the various mass estimation techniques…
An application of machine learning techniques to galaxy cluster mass estimation using the MACSIS simulations
Thomas J. Armitage, Scott T. Kay, David J. Barnes
Machine learning (ML) techniques, in particular supervised regression algorithms, are a promising new way to use multiple observables to predict a cluster's mass or other key featu…
The signal of decaying dark matter with hydrodynamical simulations
Mark R. Lovell, David Barnes, Yannick Bahé +11
Dark matter particles may decay, emitting photons. Drawing on the EAGLE family of hydrodynamic simulations of galaxy formation -- including the APOSTLE and C-EAGLE simulations -- w…
