Journal Article
Richings, J., Frenk, C., Jenkins, A., Robertson, A., & Schaller, M. (2021). A high-resolution cosmological simulation of a strong gravitational lens. Monthly Notices of the Royal Astronomical Society, 501(3), 4657-4668. https://doi.org/10.1093/mnras/staa4013

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.

Journal Article
Richings, J., Frenk, C., Jenkins, A., Robertson, A., Fattahi, A., Grand, R. J., Navarro, J., Pakmor, R., Gomez, F. A., Marinacci, F., & Oman, K. (2020). Subhalo destruction in the Apostle and Auriga simulations. Monthly Notices of the Royal Astronomical Society, 492(4), 5780-5793. https://doi.org/10.1093/mnras/stz3448

N-body simulations make unambiguous predictions for the abundance of substructures within dark matter halos. However, the inclusion of baryons in the simulations changes the picture because processes associated with the presence of a large galaxy in...

Energy equipartition between stellar and dark matter particles in cosmological simulations results in spurious growth of galaxy sizes (2019)
Journal Article
Ludlow, A. D., Schaye, J., Schaller, M., & Richings, J. (2019). Energy equipartition between stellar and dark matter particles in cosmological simulations results in spurious growth of galaxy sizes.

The impact of 2-body scattering on the innermost density profiles of dark matter haloes is well established. We use a suite of cosmological simulations and idealized numerical experiments to show that 2-body scattering is exacerbated in situations wh...
