Preliminary results from Gemini-GMOS data

Abstract

Here we show the preliminary results of a photometric study of low surface brightness objects with $\mu_{g'}~\gtrsim~25$~mag/arcsec$^2$. These objects are present in several fields obtained with GEMINI-GMOS, in the central region of the Pegasus I group. We found that their photometric characteristics are similar to the so-called dwarf spheroidal galaxies or to the ultra low surface brightness galaxies.
