Assessing subhalo finders in cosmological hydrodynamical simulations
Victor J. Forouhar Moreno, John Helly, Robert McGibbon +5
Cosmological simulations are essential for inferring cosmological and galaxy population properties based on forward-modelling, but this typically requires finding the population of…
TangoSIDM Project: Is the Stellar Mass Tully-Fisher relation consistent with SIDM?
Camila Correa, Matthieu Schaller, Joop Schaye +3
Self-interacting dark matter (SIDM) has the potential to significantly influence galaxy formation in comparison to the cold, collisionless dark matter paradigm (CDM), resulting in…
Preparing for low surface brightness science with the Vera C. Rubin Observatory: A Comparison of Observable and Simulated Intracluster Light Fractions
Sarah Brough, Syeda Lammim Ahad, Yannick M. Bahe +13
Intracluster Light (ICL) provides an important record of the interactions galaxy clusters have undergone. However, we are limited in our understanding by our measurement methods. T…
Prospects for detecting the circum- and intergalactic medium in X-ray absorption using the extended intracluster medium as a backlight
Lýdia Štofanová, Aurora Simionescu, Nastasha A. Wijers +4
The warm-hot plasma in cosmic web filaments is thought to comprise a large fraction of the gas in the local Universe. So far, the search for this gas has focused on mapping its emi…
FLAMINGO: Calibrating large cosmological hydrodynamical simulations with machine learning
Roi Kugel, Joop Schaye, Matthieu Schaller +17
To fully take advantage of the data provided by large-scale structure surveys, we need to quantify the potential impact of baryonic effects, such as feedback from active galactic n…
The FLAMINGO project: cosmological hydrodynamical simulations for large-scale structure and galaxy cluster surveys
Joop Schaye, Roi Kugel, Matthieu Schaller +17
We introduce the Virgo Consortium's FLAMINGO suite of hydrodynamical simulations for cosmology and galaxy cluster physics. To ensure the simulations are sufficiently realistic for…
EAGLE-like simulation models do not solve the entropy core problem in groups and clusters of galaxies
Edoardo Altamura, Scott T. Kay, Richard G. Bower +5
Recent high-resolution cosmological hydrodynamic simulations run with a variety of codes systematically predict large amounts of entropy in the intra-cluster medium at low redshift…
The mass-size relation of galaxy clusters
O. Contigiani, Y. M. Bahé, H. Hoekstra
The outskirts of accreting dark matter haloes exhibit a sudden drop in density delimiting their multi-stream region. Due to the dynamics of accretion, the location of this physical…
Redshift evolution of the hot intracluster gas metallicity in the C-EAGLE cluster simulations
Francesca A. Pearce, Scott T. Kay, David J. Barnes +2
The abundance and distribution of metals in galaxy clusters contains valuable information about their chemical history and evolution. By looking at how metallicity evolves with red…
CCCP and MENeaCS: (updated) weak-lensing masses for 100 galaxy clusters
Ricardo Herbonnet, Cristóbal Sifón, Henk Hoekstra +7
Large area surveys have detected significant samples of galaxy clusters that can be used to constrain cosmological parameters, provided that the masses of the clusters are measured…
Constraining the inner density slope of massive galaxy clusters
Qiuhan He, Hongyu Li, Ran Li +7
We determine the inner density profiles of massive galaxy clusters (M > M) in the Cluster-EAGLE (C-EAGLE) hydrodynamic simulations, and investi…
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…
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…
Weak lensing constraints on splashback around massive clusters
O. Contigiani, H. Hoekstra, Y. M. Bahé
The splashback radius separates the physical regimes of collapsed and infalling material around massive dark matter haloes. In cosmological simulations, this location…
Growing a `Cosmic Beast': Observations and Simulations of MACS J0717.5+3745
M. Jauzac, D. Eckert, M. Schaller +18
We present a gravitational lensing and X-ray analysis of a massive galaxy cluster and its surroundings. The core of MACS\,J0717.5+3745 (\,$10^{15}…
LoCuSS: Testing hydrostatic equilibrium in galaxy clusters
G. P. Smith, P. Mazzotta, N. Okabe +17
We test the assumption of hydrostatic equilibrium in an X-ray luminosity selected sample of 50 galaxy clusters at from the Local Cluster Substructure Survey (LoCuSS).…
Why does the environmental influence on group and cluster galaxies extend beyond the virial radius?
Yannick M. Bahe, Ian G. McCarthy, Michael L. Balogh +1
In the local Universe, galaxies in groups and clusters contain less gas and are less likely to be forming stars than their field counterparts. This effect is not limited to the cen…
The competition between confinement and ram pressure and its implications for galaxies in groups and clusters
Yannick M. Bahe, Ian G. McCarthy, Robert A. Crain +1
Ram pressure stripping of the hot gas that surrounds normal galaxies as they fall into groups and clusters (also referred to as `strangulation' or `starvation') is generally though…
