Sussing merger trees: the impact of halo merger trees on galaxy properties in a semi-analytic model (2014)
Journal Article
Lee, J., Yi, S. K., Elahi, P. J., Thomas, P. A., Pearce, F. R., Behroozi, P., …Tweed, D. (2014). Sussing merger trees: the impact of halo merger trees on galaxy properties in a semi-analytic model. Monthly Notices of the Royal Astronomical Society, 445(4), https://doi.org/10.1093/mnras/stu2039

A halo merger tree forms the essential backbone of a semi-analytic model for galaxy formation and evolution. Recent studies have pointed out that extracting merger trees from numerical simulations of structure formation is non-trivial; different tree...

Subhaloes gone Notts: subhaloes as tracers of the dark matter halo shape (2014)
Journal Article
Hoffmann, K., Planelles, S., Gaztanaga, E., Knebe, A., Pearce, F. R., Lux, H., …Sgro, M. A. (2014). Subhaloes gone Notts: subhaloes as tracers of the dark matter halo shape. Monthly Notices of the Royal Astronomical Society, 442(2), https://doi.org/10.1093/mnras/stu933

We study the shapes of subhalo distributions from four dark-matter-only simulations of Milky Way-type haloes. Comparing the shapes derived from the subhalo distributions at high resolution to those of the underlying dark matter fields, we find the fo...

Sussing merger trees: the influence of the halo finder (2014)
Journal Article
Avila, S., Knebe, A., Pearce, F. R., Schneider, A., Srisawat, C., Thomas, P. A., …Tweed, D. (2014). Sussing merger trees: the influence of the halo finder. Monthly Notices of the Royal Astronomical Society, 441(4), https://doi.org/10.1093/mnras/stu799

Merger tree codes are routinely used to follow the growth and merger of dark matter haloes in simulations of cosmic structure formation. Whereas in Srisawat et. al. we compared the trees built using a wide variety of such codes, here we study the inf... Read More about Sussing merger trees: the influence of the halo finder.

Galaxy cluster mass reconstruction project – I. Methods and first results on galaxy-based techniques (2014)
Journal Article
Old, L., Skibba, R., Pearce, F. R., Croton, D., Muldrew, S. I., Muñoz-Cuartas, J., …Wojtak, R. (2014). Galaxy cluster mass reconstruction project – I. Methods and first results on galaxy-based techniques. Monthly Notices of the Royal Astronomical Society, 441(2), 1513-1536. https://doi.org/10.1093/mnras/stu545

This paper is the first in a series in which we perform an extensive comparison of various galaxy-based cluster mass estimation techniques that utilize the positions, velocities and colours of galaxies. Our primary aim is to test the performance of t... Read More about Galaxy cluster mass reconstruction project – I. Methods and first results on galaxy-based techniques.

Subhaloes gone Notts: the clustering properties of subhaloes (2014)
Journal Article
Pujol, A., Gaztanaga, E., Giocoli, C., Knebe, A., Pearce, F. R., Skibba, R. A., …Tweed, D. (2014). Subhaloes gone Notts: the clustering properties of subhaloes. Monthly Notices of the Royal Astronomical Society, 438(4), https://doi.org/10.1093/mnras/stt2446

We present a study of the substructure finder dependence of subhalo clustering in the Aquarius Simulation. We run 11 different subhalo finders on the haloes of the Aquarius Simulation and study their differences in the density profile, mass fraction...
