  • Gravitational redshift profiles in the f(R) and symmetron models 
    Grönke, Max Balthasar; Llinares, Claudio; Mota, David (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    Aims: We investigate the gravitational redshift in clusters of galaxies in the symmetron and Hu-Sawicky f(R) models. The characteristic feature of both models is the screening mechanism that hides the fifth force in dense ...
  • Halo velocity profiles in screened modified gravity theories 
    Grönke, Max Balthasar; Llinares, Claudio; Mota, David; Winther, Hans Arnold (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Screened modified gravity predicts potentially large signatures in the peculiar velocity field that makes it an interesting probe to test gravity on cosmological scales. We investigate the signatures induced by the Symmetron ...
  • Three Lyman-α-emitting filaments converging to a massive galaxy group at z = 2.91: discussing the case for cold gas infall 
    Daddi, E.; Valentino, F.; Rich, R. M.; Neill, J. D.; Grönke, Max Balthasar; O'Sullivan, D.; Elbaz, Didier; Bournaud, F.; Finoguenov, Alexis; Marchal, A.; Delvecchio, I.; Jin, S.; Liu, D.; Strazzullo, V.; Calabro, A.; Coogan, R.; D'Eugenio, C.; Gobat, R.; Kalita, B. S.; Laursen, Peter; Martin, D. C.; Puglisi, A.; Schinnerer, E.; Wang, T. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    We have discovered a 300 kpc-wide giant Lyman-α (Lyα) nebula centered on the massive galaxy group RO-1001 at z = 2.91 in the Cosmic Evolution Survey field. Keck Cosmic Web Imager observations reveal three cold gas filaments ...
