cds-question@unistra.frgalaxiesphotometryinfrared-photometryvisible-astronomybroad-band-photometryWe present deep surface photometry of a volume-limited sample of 21 UM emission line galaxies in broadband optical UBVRI and near infra-red (NIR) HKs filters. The sample comprises 19 blue compact galaxies (BCGs) and two spirals. For some targets the exposure times are the deepest to date. For the BCG UM462 we observe a previously undetected second disk component beyond a surface brightness level of mu_B_=26mag/arcsec^2^. This is a true low surface brightness component with central surface brightness mu_0_=24.1mag/arcsec^2^ and scale length h_r_=1.5kpc. All BCGs are dwarfs, with M_B_>=-18, and very compact, with an average scale length of h_r_~1kpc. We separate the burst and host populations for each galaxy and compare them to stellar evolutionary models with and without nebular emission contribution. We also measure the A_180_ asymmetry in all filters and detect a shift from optical to NIR in the average asymmetry of the sample. This shift seems to be correlated with the morphological class of the BCGs. Using the color-asymmetry relation, we identify five BCGs in the sample as mergers, which is confirmed by their morphological class. Though clearly separated from normal galaxies in the concentration-asymmetry parameter space, we find that it is not possible to distinguish luminous starbursting BCGs from the merely star forming low luminosity BCGs.2013A&A...556A..10Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/556/A10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/171 : Michigan Emission-Line Objects (MacAlpine+ 1977-1982)J/ApJ/668/853 : Spectroscopy of UltraStrong EmL galaxies (Kakazu+, 2007)J/A+A/429/115 : JHK' photometry of Blue Compact Dwarf Galaxies (Noeske+, 2005)J/A+A/434/887 : HI data of blue compact dwarf galaxies (Huchtmeier+, 2005)J/ApJS/156/345 : Surface photometry of BCD galaxies (Gil De Paz+, 2005)J/ApJS/147/29 : BRHa data of blue compact dwarf galaxies (Gil De Paz+, 2003)J/A+A/397/463 : The Hamburg/SAO Survey for BCGs.
