Swift: A modern highly-parallel gravity and smoothed particle hydrodynamics solver for astrophysical and cosmological applications (2024)
Journal Article

Numerical simulations have become one of the key tools used by theorists in all the fields of astrophysics and cosmology. The development of modern tools that target the largest existing computing systems and exploit state-of-the-art numerical method...

Winds versus jets: a comparison between black hole feedback modes in simulations of idealized galaxy groups and clusters (2023)
Journal Article

Using the SWIFT simulation code, we compare the effects of different forms of active galactic nuclei (AGNs) feedback in idealized galaxy groups and clusters. We first present a physically motivated model of black hole (BH) spin evolution and a numeri...

The FLAMINGO project: cosmological hydrodynamical simulations for large-scale structure and galaxy cluster surveys (2023)
Journal Article

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 studies of large-scale structure, the subgrid prescriptions for stella...

KURVS: the outer rotation curve shapes and dark matter fractions of z ∼ 1.5 star-forming galaxies (2023)
Journal Article

We present first results from the KMOS Ultra-deep Rotation Velocity Survey (KURVS), aimed at studying the outer rotation curves shape and dark matter content of 22 star-forming galaxies at z ∼1.5. These galaxies represent ’typical’ star-forming discs... Read More about KURVS: the outer rotation curve shapes and dark matter fractions of z ∼ 1.5 star-forming galaxies.

The evolution of the baryon fraction in halos as a cause of scatter in the galaxy stellar mass in the EAGLE simulation (2018)
Journal Article

The EAGLE simulation suite has previously been used to investigate the relationship between the stellar mass of galaxies, M*, and the properties of dark matter halos, using the hydrodynamical reference simulation combined with a dark matter only (DMO...

Reducing biases on H0 measurements using strong lensing and galaxy dynamics: results from the eagle simulation (2017)
Journal Article

Cosmological parameter constraints from observations of time-delay lenses are becoming increasingly precise. However, there may be significant bias and scatter in these measurements due to, among other things, the so-called mass-sheet degeneracy. To...

The SAMI Galaxy Survey: understanding observations of large-scale outflows at low redshift with EAGLE simulations (2017)
Journal Article

This work presents a study of galactic outflows driven by stellar feedback. We extract main-sequence disc galaxies with stellar mass 109 ≤ M⋆/ M⊙ ≤ 5.7 × 1010 at redshift z = 0 from the highest resolution cosmological simulation of the Evolution and...

SWIFT: Using task-based parallelism, fully asynchronous communication, and graph partition-based domain decomposition for strong scaling on more than 100,000 cores (2016)
Presentation / Conference Contribution

We present a new open-source cosmological code, called SWIFT, designed to solve the equations of hydrodynamics using a particle-based approach (Smooth Particle Hydrodynamics) on hybrid shared / distributed-memory architectures. SWIFT was designed fro...
