Abell 1201: detection of an ultramassive black hole in a strong gravitational lens (2023)
Journal Article

Monthly Notices of the Royal Astronomical Society, 521(3), 3298-3322. https://doi.org/10.1093/mnras/stad587

Supermassive black holes (SMBHs) are a key catalyst of galaxy formation and evolution, leading to an observed correlation between SMBH mass MBH and host galaxy velocity dispersion σe. Outside the local Universe, measurements of MBH are usually only p... Read More about Abell 1201: detection of an ultramassive black hole in a strong gravitational lens.

Apostle-Auriga: effects of different subgrid models on the baryon cycle around Milky Way-mass galaxies (2022)
Journal Article
Kelly, A. J., Jenkins, A., Deason, A., Fattahi, A., Grand, R. J., Pakmor, R., Springel, V., & Frenk, C. S. (2022). Apostle-Auriga: effects of different subgrid models on the baryon cycle around Milky Way-mass galaxies. Monthly Notices of the Royal Astronomical Society, 514(3), 3113-3138. https://doi.org/10.1093/mnras/stac1019

Modern hydrodynamical simulations reproduce many properties of the real universe. These simulations model various physical processes, but many of these are included using ‘subgrid models’ due to resolution limits. Although different subgrid models ha...

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.

PyAutoLens: Open-Source Strong Gravitational Lensing (2021)
Journal Article
Nightingale, J., Hayes, R., Kelly, A., Amvrosiadis, A., Etherington, A., He, Q., …Robertson, A. (2021). PyAutoLens: Open-Source Strong Gravitational Lensing. The Journal of Open Source Software, 6(58), Article 2825. https://doi.org/10.21105/joss.02825

Strong gravitational lensing, which can make a background source galaxy appears multiple times due to its light rays being deflected by the mass of one or more foreground lens galaxies, provides astronomers with a powerful tool to study dark matter,...

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.

Learning dynamical information from static protein and sequencing data (2019)
Journal Article
Pearce, P., Woodhouse, F., Forrow, A., Kelly, A., Kusumaatmaja, H., & Dunkel, J. (2019). Learning dynamical information from static protein and sequencing data. Nature Communications, 10, Article 5368. https://doi.org/10.1038/s41467-019-13307-x

Many complex processes, from protein folding to neuronal network dynamics, can be described as stochastic exploration of a high-dimensional energy landscape. While efficient algorithms for cluster detection in high-dimensional spaces have been develo... Read More about Learning dynamical information from static protein and sequencing data.
