    Halo expansion in cosmological hydro simulations: toward a baryonic solution of the cusp/core problem in massive spirals 
    Gibson, Brad K.; Maccio, A. V.; Stinson, G.; Brook, C. B.; Wadsley, J.; Couchman, H. M. P.; Shen, S.; Quinn, T. (American Astronomical SocietyIOP Publishing, 2012-01-01)
    A clear prediction of the cold dark matter (CDM) model is the existence of cuspy dark matter halo density profiles on all mass scales. This is not in agreement with the observed rotation curves of spiral galaxies, challenging ...

    On the estimation and detection of the Rees–Sciama effect 
    Fullana, M. J.; Arnau, J. V.; Thacker, Robert John, 1970-; Couchman, H. M. P.; Sáez, D. (Oxford University Press, 2017-02)
    Maps of the Rees–Sciama (RS) effect are simulated using the parallel N-body code, hydra, and a run-time ray-tracing procedure. A method designed for the analysis of small, square cosmic microwave background (CMB) maps is ...
