The Three Hundred Project: The relationship between the shock and splashback radii of simulated galaxy clusters
M. Zhang, K. Walker, A. Sullivan +4
Observations of the intracluster medium (ICM) in the outskirts of galaxy clusters reveal shocks associated with gas accretion from the cosmic web. Previous work based on non-radiat…
From Particles to Pixels: How many particles do I really need to construct stellar kinematic mock observational measurements?
K. E. Harborne, C. del P. Lagos, S. M. Croom +5
This work considers the impact of resolution in the construction of mock observations of simulated galaxies. In particular, when building mock integral field spectroscopic observat…
Using dust to constrain dark matter models
Adam Ussing, Robert Mostoghiu Paun, Darren Croton +3
In this paper, we use hydrodynamic zoom-in simulations of Milky Way-type haloes to explore using dust as an observational tracer to discriminate between cold and warm dark matter (…
Predicting the Non-Thermal Pressure in Galaxy Clusters
Andrew Sullivan, Stanislav Shabala, Chris Power +2
We investigate the relationship between a galaxy cluster's hydrostatic equilibrium state, the entropy profile, , of the intracluster gas, and the system's non-thermal pressure (…
Constraining cosmological parameters using the splashback radius of galaxy clusters
Roan Haggar, Yuba Amoura, Charlie T. Mpetha +3
Cosmological parameters such as and can be measured indirectly using various methods, including galaxy cluster abundance and cosmic shear. These measurements c…
Reconsidering the dynamical states of galaxy clusters using PCA and UMAP
Roan Haggar, Federico De Luca, Marco De Petris +10
Numerous metrics exist to quantify the dynamical state of galaxy clusters, both observationally and within simulations. Many of these correlate strongly with one another, but it is…
On bursty star formation during cosmological reionization - how does it influence the baryon mass content of dark matter halos?
Anand Menon, Chris Power
The baryon mass content of dark matter halos in the early Universe depends on global factors - e.g. ionising ultraviolet (UV) radiation background - and local factors - e.g. star f…
Predicting the Scaling Relations between the Dark Matter Halo Mass and Observables from Generalised Profiles II: Intracluster Gas Emission
Andrew Sullivan, Chris Power, Connor Bottrell +2
We investigate the connection between a cluster's structural configuration and observable measures of its gas emission that can be obtained in X-ray and Sunyaev-Zeldovich (SZ) surv…
Predicting the Scaling Relations between the Dark Matter Halo Mass and Observables from Generalised Profiles I: Kinematic Tracers
Andrew Sullivan, Chris Power, Connor Bottrell
We investigate the relationship between a dark matter halo's mass profile and measures of the velocity dispersion of kinematic tracers within its gravitational potential. By predic…
