Surface brightness profiles of blue compact dwarf galaxies in the
  GOODS-N and GOODS-S field
  We investigate the structural properties of the underlying hosts of 34 blue
compact dwarf (BCD) galaxies with deep near-infrared (NIR) photometry. The BCD
sample is selected from the Cosmic Assembly Near-IR Deep Extragalactic Legacy
Survey in the Great observatories origins Deep Survey North and South fields.
We extract the surface brightness profile (SBP) in the optical F 435W and NIR F
160W bands. The SBPs of BCDs in the H band reach 26 mag arcsec^-2 at the
3\sigma level, which is so far the deepest NIR imaging of BCDs. Then we fit the
SBPs with one- and two- component Sersic models. About half of the BCDs favour
the two-component model which significantly improves the fit quality. The
effective radii of the underlying hosts of BCDs in the B band are smaller than
those of early-type dwarfs (dEs) and dwarf irregulars at a fixed luminosity.
This discrepancy is similar to findings in many previous works. However, the
difference in structural parameters between BCDs and other dwarf galaxies seems
to be less significant in the H band. Furthermore, we find a remarkable
agreement between the underlying hosts of BCDs and dEs. All dwarf galaxies seem
to follow a similar luminosity-radius relationship which suggests a unified
structural evolution for dwarf galaxies. We conclude that a possible evolution
track from BCDs to dEs cannot be ruled out, with no significant change of
structure needed in the evolutionary scenario.
