Setting the scene for BUFFALO: A study of the matter distribution in the HFF galaxy cluster MACS J0416.1-2403 and its parallel field
Elizabeth J. Gonzalez, Martín Chalela, Mathilde Jauzac +11
In the context of the BUFFALO (Beyond Ultra-deep Frontier Fields And Legacy Observations) survey, we present a new analysis of the merging galaxy cluster MACS\,J0416.1-2403 ($z = 0…
Hydrostatic mass estimates of massive galaxy clusters: a study with varying hydrodynamics flavours and non-thermal pressure support
Francesca A. Pearce, Scott T. Kay, David J. Barnes +2
We use a set of 45 simulated clusters with a wide mass range (M) to investigate the effect of varying hydrodynamics flavou…
Numerical convergence of hydrodynamical simulations of galaxy formation: the abundance and internal structure of galaxies and their cold dark matter haloes
Aaron D. Ludlow, Joop Schaye, Matthieu Schaller +1
We address the issue of numerical convergence in cosmological smoothed particle hydrodynamics simulations using a suite of runs drawn from the EAGLE project. Our simulations adopt…
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 diverse evolutionary pathways of post-starburst galaxies
M. M. Pawlik, S. McAlpine, J. W. Trayford +5
About 35 years ago a class of galaxies with unusually strong Balmer absorption lines and weak emission lines was discovered in distant galaxy clusters. These objects, alternatively…
Energy equipartition between stellar and dark matter particles in cosmological simulations results in spurious growth of galaxy sizes
Aaron D. Ludlow, Joop Schaye, Matthieu Schaller +1
The impact of 2-body scattering on the innermost density profiles of dark matter haloes is well established. We use a suite of cosmological simulations and idealised numerical expe…
The Dynamics and Distribution of Angular Momentum in HiZELS Star-Forming Galaxies at z = 0.8 - 3.3
S. Gillman, A. M. Swinbank, A. L. Tiley +18
We present adaptive optics assisted integral field spectroscopy of 34 star-forming galaxies at = 0.8-3.3 selected from the HiZELS narrow-band survey. We measure the kinematics…
SEAGLE--II: Constraints on feedback models in galaxy formation from massive early type strong lens galaxies
Sampath Mukherjee, Leon V. E. Koopmans, R. Benton Metcalf +5
We use nine different galaxy formation scenarios in ten cosmological simulation boxes from the EAGLE suite of ΛCDM hydrodynamical simulations to assess the impact of feedback mecha…
