17 Oct 2003 | | Journal: | Astrophys.J. 606 (2004) 683-701 | | Subject: | astro-ph | | Affiliation: | 1,2), Johan Richard , Konrad Kuijken ( Caltech, OMP/Toulouse, Leiden | | Abstract: | We derive the luminosity function of high-redshift Lyman alpha emitting sources from a deep, blind, spectroscopic survey that utilized strong-lensing magnification by intermediate-redshift clusters of galaxies. We observed carefully selected regions near 9 clusters, consistent with magnification factors generally greater than 10 for the redshift range 4.5L) proportional to L^-1 over 10^41 to 10^42.5 erg/s. When combined with the results of other surveys, limited at higher luminosities, our results suggest evidence for the suppression of star formation in low-mass halos, as predicted in popular models of galaxy formation. | | Source: | arXiv, astro-ph/0310478 | | Services: | Forum | Review | PDF | Favorites | |
