Are the fates of supermassive black holes and galaxies determined by individual mergers, or by the properties of their host haloes?
Jonathan J. Davies, Andrew Pontzen, Robert A. Crain
The fates of massive galaxies are tied to the evolution of their central supermassive black holes (BHs), due to the influence of AGN feedback. Correlations within simulated galaxy…
Environmental effects in Herschel observations of the ionized carbon content of star forming dwarf galaxies in the Virgo cluster
Robert Minchin, Dario Fadda, Rhys Taylor +2
We use archival Herschel data to examine the singly ionized carbon ([CII]) content of 14 star forming dwarf galaxies in the Virgo cluster. We use spectral energy distribution (SED)…
Galaxy mergers can initiate quenching by unlocking an AGN-driven transformation of the baryon cycle
Jonathan J. Davies, Andrew Pontzen, Robert A. Crain
We use zoom simulations to show how merger-driven disruption of the gas disc in a galaxy provides its central active galactic nucleus (AGN) with fuel to drive outflows that entrain…
Predictions for the X-ray circumgalactic medium of edge-on discs and spheroids
Anna Nica, Benjamin D. Oppenheimer, Robert A. Crain +5
We investigate how the X-ray circumgalactic medium (CGM) of present-day galaxies depends on galaxy morphology and azimuthal angle using mock observations generated from the EAGLE c…
An EAGLE's View of Ex-situ Galaxy Growth
Thomas A. Davison, Mark A. Norris, Joel L. Pfeffer +2
Modern observational and analytic techniques now enable the direct measurement of star formation histories and the inference of galaxy assembly histories. However, current theoreti…
Quenching and morphological evolution due to circumgalactic gas expulsion in a simulated galaxy with a controlled assembly history
Jonathan J. Davies, Robert A. Crain, Andrew Pontzen
We examine the influence of dark matter halo assembly on the evolution of a simulated galaxy. Starting from a zoom-in simulation of a star-forming galaxy evolved wit…
High-resolution, 3D radiative transfer modelling IV. AGN-powered dust heating in NGC 1068
S. Viaene, A. Nersesian, J. Fritz +18
Dust emission, an important diagnostic of star formation and ISM mass throughout the Universe, can be powered by sources unrelated to ongoing star formation. In the framework of th…
EAGLE and Illustris-TNG predictions for resolved eROSITA X-ray observations of the circumgalactic medium around normal galaxies
Benjamin D. Oppenheimer, Akos Bogdan, Robert A. Crain +8
We simulate stacked observations of nearby hot X-ray coronae associated with galaxies in the EAGLE and Illustris-TNG hydrodynamic simulations. A forward modeling pipeline is develo…
The quenching and morphological evolution of central galaxies is facilitated by the feedback-driven expulsion of circumgalactic gas
Jonathan J. Davies, Robert A. Crain, Benjamin D. Oppenheimer +1
We examine the connection between the properties of the circumgalactic medium (CGM) and the quenching and morphological evolution of central galaxies in the EAGLE and IllustrisTNG…
Feedback from supermassive black holes transforms centrals into passive galaxies by ejecting circumgalactic gas
Benjamin D. Oppenheimer, Jonathan J. Davies, Robert A. Crain +6
Davies et al. (2019) established that for L^* galaxies the fraction of baryons in the circumgalactic medium (CGM) is inversely correlated with the mass of their central supermassiv…
The gas fractions of dark matter haloes hosting simulated galaxies are governed by the feedback history of their black holes
Jonathan J. Davies, Robert A. Crain, Ian G. McCarthy +4
We examine the origin of scatter in the relationship between the gas fraction and mass of dark matter haloes hosting present-day central galaxies in the EAGLE simula…
A Heavy Baryonic Galactic Disc
Jonathan Davies
We investigate the possibility that the observed rotation of galaxies can be accounted for by invoking a massive baryonic disc with no need for non-baryonic dark matter or a massiv…
