Abstract: Context. In the last years, a new generation of large-scale imaging surveys have probed for the first time wide field regions around some nearby galaxies at unprecedented low surface brightness regime (∼ 28.0-29.0 mag arcsec −2 ). This offers a chance of discovering very faint dwarf satellites by means of systematic visual inspection of these public deep images. Aims. In this paper we report the first results of a systematic survey of faint dwarf spheroidal galaxies in the vicinity of the bright late-type spir… Show more

“…Unfortunately, the small HST FoV prevents us from exploring further any trends in the spatial distribution of RGB and AGB stars in Scl-MM-dw2. Martinez-Delgado et al (2021) recently performed a visual NGC 253 satellite search using the DES data, and reported three new dwarf candidates, one of which is the same object we independently discovered and named as Scl-MM-dw3. The other two are located outside our PISCeS footprint, and their discoveries suggest that there might be more satellites to be discovered at larger radii from NGC 253.…”
