COLIBRE: calibrating subgrid feedback in cosmological simulations that include a cold gas phase
Evgenii Chaikin, Joop Schaye, Matthieu Schaller +17
We present the calibration of stellar and active galactic nucleus (AGN) feedback in the subgrid model for the new COLIBRE hydrodynamical simulations of galaxy formation. COLIBRE di…
The COLIBRE project: cosmological hydrodynamical simulations of galaxy formation and evolution
Joop Schaye, Evgenii Chaikin, Matthieu Schaller +18
We present the COLIBRE galaxy formation model and the COLIBRE suite of cosmological hydrodynamical simulations. COLIBRE includes new models for radiative cooling, dust grains, star…
Resolution criteria to avoid artificial clumping in Lagrangian hydrodynamic simulations with a multi-phase interstellar medium
Sylvia Ploeckinger, Folkert S. J. Nobels, Matthieu Schaller +1
Large-scale cosmological galaxy formation simulations typically prevent gas in the interstellar medium (ISM) from cooling below K. This has been motivated by the ina…
Tests of subgrid models for star formation using simulations of isolated disk galaxies
Folkert S. J. Nobels, Joop Schaye, Matthieu Schaller +3
We use smoothed-particle hydrodynamics simulations of isolated Milky Way-mass disk galaxies that include cold, interstellar gas to test subgrid prescriptions for star formation (SF…
Winds versus jets: a comparison between black hole feedback modes in simulations of idealized galaxy groups and clusters
Filip Huško, Cedric G. Lacey, Joop Schaye +2
Using the SWIFT simulation code we study different forms of active galactic nuclei (AGN) feedback in idealized galaxy groups and clusters. We first present a physically motivated m…
Hydrodynamic simulations of the Disk of Gas Around Supermassive black holes (HDGAS) -I; Molecular Gas Dynamics
Mojtaba Raouf, Serena Viti, S. García-Burillo +9
We present hydrodynamic simulations of the interstellar medium (ISM) within the circumnuclear disk (CND) of a typical AGN-dominated galaxy influenced by mechanical feedback from an…
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…
SWIFT: A modern highly-parallel gravity and smoothed particle hydrodynamics solver for astrophysical and cosmological applications
Matthieu Schaller, Josh Borrow, Peter W. Draper +24
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 ex…
The impact of stochastic modeling on the predictive power of galaxy formation simulations
Josh Borrow, Matthieu Schaller, Yannick M. Bahe +5
All modern galaxy formation models employ stochastic elements in their sub-grid prescriptions to discretise continuous equations across the time domain. In this paper, we investiga…
A thermal-kinetic subgrid model for supernova feedback in simulations of galaxy formation
Evgenii Chaikin, Joop Schaye, Matthieu Schaller +3
We present a subgrid model for supernova feedback designed for cosmological simulations of galaxy formation that may include a cold interstellar medium (ISM). The model uses therma…
Spin-driven jet feedback in idealised simulations of galaxy groups and clusters
Filip Huško, Cedric G. Lacey, Joop Schaye +2
We implement a black hole spin evolution and jet feedback model into SWIFT, a smoothed particle hydrodynamics code. The jet power is determined self-consistently assuming Bondi acc…
The importance of the way in which supernova energy is distributed around young stellar populations in simulations of galaxies
Evgenii Chaikin, Joop Schaye, Matthieu Schaller +3
Supernova (SN) feedback plays a crucial role in simulations of galaxy formation. Because blastwaves from individual SNe occur on scales that remain unresolved in modern cosmologica…
The interplay between AGN feedback and precipitation of the intracluster medium in simulations of galaxy groups and clusters

Using high-resolution hydrodynamical simulations of galaxy clusters, we study the interaction between the brightest cluster galaxy, its supermassive black hole (BH) and the intracl…
The importance of black hole repositioning for galaxy formation simulations
Yannick M. Bahé, Joop Schaye, Matthieu Schaller +6
Active galactic nucleus (AGN) feedback from accreting supermassive black holes (SMBHs) is an essential ingredient of galaxy formation simulations. The orbital evolution of SMBHs is…
