The SIBELIUS Project: E Pluribus Unum (2021)
Journal Article
Sawala, T., McAlpine, S., Jasche, J., Lavaux, G., Jenkins, A., Johansson, P. H., & Frenk, C. S. (2022). The SIBELIUS Project: E Pluribus Unum. Monthly Notices of the Royal Astronomical Society, 509(1), 1432-1446. https://doi.org/10.1093/mnras/stab2684

We introduce ‘Simulations Beyond The Local Universe’ (SIBELIUS) that connect the Local Group (LG) to its cosmic environment. We show that introducing hierarchical small-scale perturbations to a density field constrained on large scales by observation... Read More about The SIBELIUS Project: E Pluribus Unum.

Determining the full satellite population of a Milky Way-mass halo in a highly resolved cosmological hydrodynamic simulation (2021)
Journal Article
Grand, R. J., Marinacci, F., Pakmor, R., Simpson, C. M., Kelly, A. J., Gómez, F. A., …White, S. D. (2021). Determining the full satellite population of a Milky Way-mass halo in a highly resolved cosmological hydrodynamic simulation. Geometry & Topology, 507(4), 4953-4967. https://doi.org/10.1093/mnras/stab2492

We investigate the formation of the satellite galaxy population of a Milky Way-mass halo in a very highly resolved magnetohydrodynamic cosmological zoom-in simulation (baryonic mass resolution mb = 800 M⊙⁠). We show that the properties of the central... Read More about Determining the full satellite population of a Milky Way-mass halo in a highly resolved cosmological hydrodynamic simulation.

Constraints on the properties of warm dark matter using the satellite galaxies of the Milky Way (2021)
Journal Article
Newton, O., Leo, M., Cautun, M., Jenkins, A., Frenk, C. S., Lovell, M. R., …Cole, S. (2021). Constraints on the properties of warm dark matter using the satellite galaxies of the Milky Way. Journal of Cosmology and Astroparticle Physics, 2021(08), Article 062. https://doi.org/10.1088/1475-7516/2021/08/062

The satellite galaxies of the Milky Way (MW) are effective probes of the underlying dark matter (DM) substructure, which is sensitive to the nature of the DM particle. In particular, a class of DM models have a power spectrum cut-off on the mass scal... Read More about Constraints on the properties of warm dark matter using the satellite galaxies of the Milky Way.

An optimal non-linear method for simulating relic neutrinos (2021)
Journal Article
Elbers, W., Frenk, C. S., Jenkins, A., Li, B., & Pascoli, S. (2021). An optimal non-linear method for simulating relic neutrinos. Monthly Notices of the Royal Astronomical Society, 507(2), 2614-2631. https://doi.org/10.1093/mnras/stab2260

Cosmology places the strongest current limits on the sum of neutrino masses. Future observations will further improve the sensitivity and this will require accurate cosmological simulations to quantify possible systematic uncertainties and to make pr...

Indra: a public computationally accessible suite of cosmological N-body simulations (2021)
Journal Article
Falck, B., Wang, J., Jenkins, A., Lemson, G., Medvedev, D., Neyrinck, M. C., & Szalay, A. S. (2021). Indra: a public computationally accessible suite of cosmological N-body simulations. Monthly Notices of the Royal Astronomical Society, 506(2), 2659-2670. https://doi.org/10.1093/mnras/stab1823

Indra is a suite of large-volume cosmological N-body simulations with the goal of providing excellent statistics of the large-scale features of the distribution of dark matter. Each of the 384 simulations is computed with the same cosmological parame... Read More about Indra: a public computationally accessible suite of cosmological N-body simulations.

The origin of X-ray coronae around simulated disc galaxies (2021)
Journal Article
Kelly, A. J., Jenkins, A., & Frenk, C. S. (2021). The origin of X-ray coronae around simulated disc galaxies. Monthly Notices of the Royal Astronomical Society, 502(2), 2934-2951. https://doi.org/10.1093/mnras/stab255

The existence of hot, accreted gaseous coronae around massive galaxies is a long-standing central prediction of galaxy formation models in the ΛCDM cosmology. While observations now confirm that extraplanar hot gas is present around late-type galaxie... Read More about The origin of X-ray coronae around simulated disc galaxies.

Setting the stage: structures from Gaussian random fields (2021)
Journal Article
Sawala, T., Jenkins, A., McAlpine, S., Jasche, J., Lavaux, G., Johansson, P. H., & Frenk, C. S. (2021). Setting the stage: structures from Gaussian random fields. Monthly Notices of the Royal Astronomical Society, 501(4), 4759-4776. https://doi.org/10.1093/mnras/staa3568

We study structure formation in a set of cosmological simulations to uncover the scales in the initial density field that gave rise to the formation of present-day structures. Our simulations share a common primordial power spectrum (here Λ cold dark... Read More about Setting the stage: structures from Gaussian random fields.

A high-resolution cosmological simulation of a strong gravitational lens (2021)
Journal Article

We present a cosmological hydrodynamical simulation of a 1013 M⊙ galaxy group and its environment (out to 10 times the virial radius) carried out using the EAGLE model of galaxy formation. Exploiting a novel technique to increase the resolution of th... Read More about A high-resolution cosmological simulation of a strong gravitational lens.
