The Shapes of the Rotation Curves of Star-forming Galaxies Over the Last 10 Gyr
Alfred L. Tiley, A. M. Swinbank, C. M. Harrison +16
We analyse maps of the spatially-resolved nebular emission of 1500 star-forming galaxies at - from deep KMOS and MUSE observations to measure the average…
The relationship between the morphology and kinematics of galaxies and its dependence on dark matter halo structure in EAGLE
Adrien C. R. Thob, Robert A. Crain, Ian G. McCarthy +7
We investigate the connection between the morphology and internal kinematics of the stellar component of central galaxies with mass in the EAGL…
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…
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…
SWIFT: Maintaining weak-scalability with a dynamic range of in time-step size to harness extreme adaptivity
Josh Borrow, Richard G. Bower, Peter W. Draper +2
Cosmological simulations require the use of a multiple time-stepping scheme. Without such a scheme, cosmological simulations would be impossible due to their high level of dynamic…
Ring Galaxies in the EAGLE Hydrodynamical Simulations
Ahmed Elagali, Claudia D. P. Lagos, O. Ivy Wong +5
We study the formation and evolution of ring galaxies in the Evolution and Assembly of GaLaxies and their Environments (EAGLE) simulations. We use the largest reference model Ref-L…
The oxygen abundance gradients in the gas discs of galaxies in the EAGLE simulation
Patricia B. Tissera, Yetli Rosas-Guevara, Richard G. Bower +5
We use the EAGLE simulations to study the oxygen abundance gradients of gas discs in galaxies within the stellar mass range [10^9.5, 10^10.8]Mo at z=0. The estimated median oxygen…
The evolution of the baryon fraction in halos as a cause of scatter in the galaxy stellar mass in the EAGLE simulation
Andrea Kulier, Nelson Padilla, Joop Schaye +5
The EAGLE simulation suite has previously been used to investigate the relationship between the stellar mass of galaxies, , and the properties of dark matter halos, using th…
An Efficient SIMD Implementation of Pseudo-Verlet Lists for Neighbour Interactions in Particle-Based Codes
James S. Willis, Matthieu Schaller, Pedro Gonnet +2
In particle-based simulations, neighbour finding (i.e finding pairs of particles to interact within a given range) is the most time consuming part of the computation. One of the be…
SEAGLE - I: A pipeline for simulating and modeling strong lenses from cosmological hydrodynamic simulations
Sampath Mukherjee, Léon. V. E. Koopmans, Robert Benton Metcalf +8
In this paper we introduce the SEAGLE (i.e. Simulating EAGLE LEnses) program, that approaches the study of galaxy formation through strong gravitational lensing, using a suite of h…
The origin of diverse -element abundances in galaxy discs
J. Ted Mackereth, Robert A. Crain, Ricardo P. Schiavon +3
Spectroscopic surveys of the Galaxy reveal that its disc stars exhibit a spread in at fixed , manifest at some locations as a bimodality. The ori…
Galaxy Formation Efficiency and the Multiverse Explanation of the Cosmological Constant with EAGLE Simulations
Luke A. Barnes, Pascal J. Elahi, Jaime Salcido +6
Models of the very early universe, including inflationary models, are argued to produce varying universe domains with different values of fundamental constants and cosmic parameter…
What to expect from dynamical modelling of galactic haloes II: the spherical Jeans equation
Wenting Wang, Jiaxin Han, Shaun Cole +3
The spherical Jeans equation (SJE) is widely used in dynamical modelling of the Milky Way (MW) halo potential. We use haloes and galaxies from the cosmological Millennium-II simula…
