  • Degeneracies between modified gravity and baryonic physics 
    Seiff Ellewsen, Thor Andreas; Falck, Bridget Lynn; Mota, David (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    In order to determine the observable signatures of modified gravity theories, it is important to consider the effect of baryonic physics. We used a modified version of the ISIS code to run cosmological hydrodynamic simulations ...
  • Density-dependent clustering - I. Pulling back the curtains on motions of the BAO peak 
    Neyrinck, Mark; Szapudi, Istvan; McCullagh, N.; Szalay, Alexander S; Falck, Bridget Lynn; Wang, Jie (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The most common statistic used to analyse large-scale structure surveys is the correlation function, or power spectrum. Here, we show how ‘slicing’ the correlation function on local density brings sensitivity to interesting ...
  • The Effect of Corner Modes in the Initial Conditions of Cosmological Simulations 
    Falck, Bridget Lynn; McCullagh, N.; Neyrinck, M. C.; Wang, J.; Szalay, A. S. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)

  • Probing modified gravity in cosmic filaments 
    Ho, Alex; Gronke, Max Balthasar; Falck, Bridget Lynn; Mota, David (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Multiple modifications of general relativity (GR) have been proposed in the literature in order to understand the nature of the accelerated expansion of the Universe. However, thus far all the predictions of GR have been ...
  • Using voids to unscreen modified gravity 
    Falck, Bridget Lynn; Koyama, Kazuya; Zhao, Gong-Bo; Cautun, Marius (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The Vainshtein mechanism, present in many models of gravity, is very effective at screening dark matter haloes such that the fifth force is negligible and general relativity is recovered within their Vainshtein radii. ...
