The Dwarf Galaxy Population of the Dorado group down to M V ≈ −

We present V and I CCD photometry of suspected low-surface brightness dwarf galaxies detected in a survey covering ∼ 2.4 deg2 around the central region of the Dorado group of galaxies. The low-surface brightness galaxies were chosen based on their sizes and magnitudes at the limiting isophote of 26.0Vμ. The selected galaxies have magnitudes brighter than V ≈ 20 (MV ≈ −11 for an assumed distance to the group of 17.2 Mpc), with central surface brightnesses μ0 > 22.5 V mag/arcsec 2, scale lengths Based on the data collected at the Cerro Tololo Interamerican Observatory and Las Campanas Observatory, Chile Visiting astronomer, Cerro Tololo Interamerican Observatory (CTIO).
