One major difficulty in probing the nature of Lyman break galaxies
(LBGs) at z ˜ 3 is the mismatch between our best images of LBGs,
which are in the rest-UV, and the best images of local galaxies, which
are in the rest-optical. To make direct comparisons between LBGs at z
˜ 3 and more local star-forming galaxies, we use HST/STIS to image
a set of 12 nearby (z<0.05) H II galaxies in the FUV and a set of 14
luminous blue compact galaxies (LBCGs) at moderate redshift (z ˜
0.5) in the NUV, corresponding to the rest-FUV. We then subject both
sets of galaxy images to the same morphological measurements recently
applied to LBGs at z ˜ 3 in the Hubble Deep Field-North. We find
many qualitative and quantitative similarities between the rest-FUV
characteristics of distant LBGs and of the more nearby starburst
samples, including sizes, asymmetries, and concentrations. This implies
that, like the nearby H II galaxies and LBCGs, LBGs may be predominately
low-mass, extreme starbursts, with a high merger fraction.
