dc.description.abstractWe present a new maximum likelihood method for the calculation of galaxy luminosity functions (LFs) from multiband photometric surveys without spectroscopic data. The method evaluates the likelihood of a trial LF by directly comparing the predicted distribution of fluxes in a multidimensional photometric space to the observations, and thus does not require the intermediate step of calculating photometric redshifts. We apply this algorithm to similar to 27 000 galaxies with m(R) < 25 in MUSYC-ECDFS, with a focus on recovering the LF of field galaxies at z < 1.2. Our deepest LFs reach M-r approximate to -14 and show that the field galaxy LF deviates from a Schechter function, exhibiting a steep upturn at intermediate magnitudes that is due to galaxies of late spectral types.
