    Cosmological model dependence of the galaxy luminosity function: far-infrared results in the Lemaître-Tolman-Bondi model
    (2013) Iribarrem, A; Andreani, P; Gruppioni, C; February, S; Ribeiro, M B; Berta, S; Le Floc’h, E; Magnelli, B; Nordon, R; Popesso, P; Pozzi, F; Riguccini, L
    Aims. This is the first paper of a series aiming at investigating galaxy formation and evolution in the giant-void class of the Lemaître-Tolman-Bondi (LTB) models that best fits current cosmological observations. Here we investigate the luminosity function (LF) methodology, and how its estimates would be affected by a change on the cosmological model assumed in its computation. Are the current observational constraints on the allowed cosmology enough to yield robust LF results?
