Major mergers going Notts: challenges for modern halo finders (2015)
Journal Article
Behroozi, P., Knebe, A., Pearce, F. R., Elahi, P., Han, J., Lux, H., …Srisawat, C. (2015). Major mergers going Notts: challenges for modern halo finders. Monthly Notices of the Royal Astronomical Society, 454(3), https://doi.org/10.1093/mnras/stv2046

Merging haloes with similar masses (i.e. major mergers) pose significant challenges for halo finders. We compare five halo-finding algorithms’ (ahf, hbt, rockstar, subfind, and velociraptor) recovery of halo properties for both isolated and cosmologi...

nIFTy cosmology: comparison of galaxy formation models (2015)
Journal Article
Knebe, A., Pearce, F. R., Thomas, P. A., Benson, A., Blaizot, J., Bower, R., …Yi, S. K. (2015). nIFTy cosmology: comparison of galaxy formation models. Monthly Notices of the Royal Astronomical Society, 451(4), https://doi.org/10.1093/mnras/stv1149

We present a comparison of 14 galaxy formation models: 12 different semi-analytical models and 2 halo occupation distribution models for galaxy formation based upon the same cosmological simulation and merger tree information derived from it. The par... Read More about nIFTy cosmology: comparison of galaxy formation models.

Solving the puzzle of subhalo spins (2015)
Journal Article
Wang, Y., Lin, W., Pearce, F. R., Lux, H., Muldrew, S. I., & Onions, J. (2015). Solving the puzzle of subhalo spins. Astrophysical Journal, 801(2), Article 93. https://doi.org/10.1088/0004-637X/801/2/93

Investigating the spin parameter distribution of subhalos in two high-resolution isolated halo simulations, recent work by Onions et al. suggested that typical subhalo spins are consistently lower than the spin distribution found for field halos. To... Read More about Solving the puzzle of subhalo spins.

Numerical simulation of two-dimensional Kelvin-Helmholtz instability using weakly compressible smoothed particle hydrodynamics (2015)
Journal Article
Yue, T., Pearce, F., Kruisbrink, A., & Morvan, H. (2015). Numerical simulation of two-dimensional Kelvin-Helmholtz instability using weakly compressible smoothed particle hydrodynamics. International Journal for Numerical Methods in Fluids, 78(5), https://doi.org/10.1002/fld.4017

The growth of the Kelvin–Helmholtz instability generated at the interface between two ideal gases is studied by means of a Smoothed Particle Hydrodynamics (SPH) scheme suitable for multi-fluids. The SPH scheme is based on the continuity equation appr...
