Integral-field spectroscopy of a Lyman-break galaxy at z=3.2: evidence for merging

Abstract:

We present spatially-resolved, rest-frame optical spectroscopy of a Lyman-break galaxy (LBG), Q0347-383 C5, obtained with SINFONI on the VLT. This galaxy, among the % brightest LBGs, is only the second LBG observed with an integral-field spectrograph. It was first described by Pettini et al. (2001, ApJ, 554, 981), who obtained WFPC2 F702W imaging and longslit spectroscopy in the -band. We find that the emission line morphology is dominated by two unresolved blobs at a projected distance of 5 ...
