    The Herschel census of infrared SEDs through cosmic time by Symeonidis, M, Vaccari, M, Berta, S, Page, M, Lutz, D, Arumugam, V, Aussel, H, Bock, J, Boselli, A, Buat, V, Capak, P, Clements, D, Conley, A, Conversi, L, Cooray, A, Dowell, C, Farrah, D, Franceschini, A, Giovannoli, E, Glenn, J, Griffin, M, Hatziminaoglou, E, Hwang, H, Ibar, E, Ilbert, O

    Published 2013
    “…The unique angle of this work is the rigorous analysis of survey selection effects, making this the first study of the star-formation-dominated, IR-luminous population within a framework almost entirely free of selection biases. We find that IR-luminous galaxies have spectral energy distributions (SEDs) with broad far-IR peaks characterized by cool/extended dust emission and average dust temperatures in the 25-45 K range. …”
