J/ApJ/639/724       Tadpole galaxies in the Hubble UDF         (Straughn+, 2006)

Tracing galaxy assembly: tadpole galaxies in the Hubble Ultra Deep Field. Straughn A.N., Cohen S.H., Ryan R.E., Hathi N.P., Windhorst R.A., Jansen R.A. <Astrophys. J., 639, 724-730 (2006)> =2006ApJ...639..724S

II/258) an abundance of galaxies is seen with a knot at one end plus an extended tail, resembling a tadpole. These "tadpole galaxies" appear dynamically unrelaxed - presumably in an early merging stage - where tidal interactions likely created the distorted knot-plus-tail morphology. Here we systematically select tadpole galaxies from the HUDF and study their properties as a function of their photometric redshifts. File Summary:
