Burgarella, D., Le Floc'h, E., Takeuchi, T. T., Huang, J. S., Buat, V., Rieke, G. H., Tyler, K. D., 2007 Lyman break galaxies at z ~ 1 and the evolution of dust attenuation in star-forming galaxies with redshift MNRAS, 380, 986 (extragalactic)
K. Tyler, in collaboration with E. Le Floc'h (Hawaii) and G. Rieke (Arizona), investigated the mid- and far-IR properties of ULIRGs and HyLIRGs at high redshift (1.5 < z < 3.0) in the Bootes field. Comparisons with similar, local sources and limits on the cold dust peak reveal that the high-redshift sources are most likely dominated by AGN emission in the mid-IR with limited contributions to star formation. K. Tyler, with the CNOC2 collaboration, is investigating the effects of the group environment on star formation in galaxies at intermediate redshifts (0.3 < z < 0.55) using Spitzer. (extragalactic)
