Classifying galaxies according to their H I content
(Oxford University Press, 2020)
We use machine learning to classify galaxies according to their H I content, based on both their optical photometry and environmental properties. The data used for our analyses are the outputs in the range z = 0–1 from ...
Testing galaxy formation simulations with damped Lyman-α abundance and metallicity evolution
(Oxford University Press, 2020)
We examine the properties of damped Lyman-α absorbers (DLAs) emerging from a single set of cosmological initial conditions in two state-of-the-art cosmological hydrodynamic simulations: SIMBA and TECHNICOLOR DAWN. The ...
A New Model For Including Galactic Winds in Simulations of Galaxy Formation II: Implementation of PhEW in Cosmological Simulations
(Monthly Notices of the Royal Astronomical Society, 2021)
Although galactic winds play a critical role in regulating galaxy formation, hydrodynamic cosmological simulations
do not resolve the scales that govern the interaction between winds and the ambient circumgalactic medium ...
The three hundred project: The stellar and gas profiles
(Oxford University Press, 2020)
Using the catalogues of galaxy clusters from The Three Hundred project, modelled with both hydrodynamic simulations (GADGET-X and GADGET-MUSIC), and semi-analytical models (SAMs), we study the scatter and self-similarity ...
The impact of quenching on galaxy profiles in the SIMBA simulation
(Oxford University Press, 2020)
We study specific star formation rate (sSFR) and gas profiles of star-forming (SF) and green valley (GV) galaxies in the SIMBA cosmological hydrodynamic simulation. SF galaxy half-light radii (Rhalf) at z = 0 and their ...
Photometric properties of reionization-epoch galaxies in the SIMBA simulations
(Oxford University Press, 2020)
We study the photometric properties and sizes of the reionization-epoch galaxies in high-resolution SIMBA cosmological hydrodynamical simulations with box sizes of [25,50]h−1Mpc. Assuming various attenuation laws, we ...
Jet feedback and the photon underproduction crisis in SIMBA
(Oxford University Press, 2020-10-01)
We examine the impact of black hole jet feedback on the properties of the low-redshift intergalactic medium (IGM) in the SIMBA
simulation, with a focus on the Lyα forest mean flux decrement DA. Without jet feedback, we ...
A new model for including galactic winds in simulations of galaxy formation – I. Introducing the Physically Evolved Winds (PhEW) model
(Oxford University Press, 2020-07-08)
The propagation and evolution of cold galactic winds in galactic haloes is crucial to galaxy formation models. However, modelling
of this process in hydrodynamic simulations of galaxy formation is oversimplified owing to ...
The circumgalactic medium from the camels simulations: Forecasting constraints on feedback processes from future Sunyaev–Zeldovich observations
(IOP Publishing, 2022)
It is important to understand the cycle of baryons through the circumgalactic medium (CGM) in the context of
galaxy formation and evolution. In this study, we forecast constraints on the feedback processes heating the ...
The CAMELS multifield data set: Learning the universe’s fundamental parameters with artificial intelligence
(IOP, 2022)
We present the Cosmology and Astrophysics with Machine Learning Simulations (CAMELS) Multifield Data set
(CMD), a collection of hundreds of thousands of 2D maps and 3D grids containing many different properties of
cosmic ...
