Tadpole Galaxies in the Near-Infrared
Abstract
We present results of a multiwavelength study of tadpole galaxies in the Hubble Ultra Deep Field. Previously selected on their distinct asymmetric, knot-plus-tail morphologies in the deep HST i'-band data (Straughn et al. 2006), we now investigate this sample in the deep WFC3 near-infrared imaging. Spanning a redshift range of 0.5<z<3.6, the tadpole candidates are on average ~half the average age of the field sample and have somewhat higher stellar masses determined from SED fits. Visual inspection of the H-band morphologies reveal that most galaxies do not retain their distinct tadpole morphology in the infrared data; however, we find that the higher redshift galaxies in the sample (z>2) generally do keep their irregular morpholgoy, in agreement with previous studies.
