Journal Article

The detection of planar structures within the satellite systems of both the Milky Way (MW) and Andromeda (M31) has been reported as being in stark contradiction to the predictions of the standard cosmological model (Λ cold dark matter – ΛCDM). Given... Read More about Planes of satellite galaxies: when exceptions are the rule.

Weak lensing by voids in modified lensing potentials (2015)
Journal Article
Barreira, A., Cautun, M., Li, B., Baugh, C., & Pascoli, S. (2015). Weak lensing by voids in modified lensing potentials. Journal of Cosmology and Astroparticle Physics, 2015(08), https://doi.org/10.1088/1475-7516/2015/08/028

We study lensing by voids in Cubic Galileon and Nonlocal gravity cosmologies, which are examples of theories of gravity that modify the lensing potential. We find voids in the dark matter and halo density fields of N-body simulations and compute thei... Read More about Weak lensing by voids in modified lensing potentials.

A new spin on discs of satellite galaxies (2015)
Journal Article
Cautun, M., Wang, W., Frenk, C., & Sawala, T. (2015). A new spin on discs of satellite galaxies. Monthly Notices of the Royal Astronomical Society, 449(3), 2576-2587. https://doi.org/10.1093/mnras/stv490

We investigate the angular and kinematic distributions of satellite galaxies around a large sample of bright isolated primaries in the spectroscopic and photometric catalogues of the Sloan Digital Sky Survey (SDSS). We detect significant anisotropy i... Read More about A new spin on discs of satellite galaxies.
