Making use of sub-resolution haloes in N-body simulations (2021)
Journal Article
Armijo, J., Baugh, C. M., Padilla, N. D., Norberg, P., & Arnold, C. (2022). Making use of sub-resolution haloes in N-body simulations. Monthly Notices of the Royal Astronomical Society, 510(1), 29-33. https://doi.org/10.1093/mnrasl/slab122

Conservative mass limits are often imposed on the dark matter halo catalogues extracted from N-body simulations. By comparing simulations with different mass resolutions, at z = 0 we find that even for haloes resolved by 100 particles, the lower reso...

A sparse regression approach to modelling the relation between galaxy stellar masses and their host haloes (2021)
Journal Article
Icaza-Lizaola, M., Bower, R. G., Norberg, P., Cole, S., Schaller, M., & Egan, S. (2021). A sparse regression approach to modelling the relation between galaxy stellar masses and their host haloes. Monthly Notices of the Royal Astronomical Society, 507(3), 4584-4602. https://doi.org/10.1093/mnras/stab2368

Sparse regression algorithms have been proposed as the appropriate framework to model the governing equations of a system from data, without needing prior knowledge of the underlying physics. In this work, we use sparse regression to build an accurat... Read More about A sparse regression approach to modelling the relation between galaxy stellar masses and their host haloes.

Rosella: a mock catalogue from the P-Millennium simulation (2021)
Journal Article

The scientific exploitation of the Dark Energy Spectroscopic Instrument Bright Galaxy Survey (DESI BGS) data requires the construction of mocks with galaxy population properties closely mimicking those of the actual DESI BGS targets. We create a high... Read More about Rosella: a mock catalogue from the P-Millennium simulation.
