On the scale of dwarf galaxies, several tensions between observations and thetheory of structure formation have been identified in the Local Group ofgalaxies. One of them, the plane-of-satellite problem describes thedistribution and motion of dwarf galaxies around their hosts being planar andco-moving. To extend these studies, we have surveyed the nearby Centaurus groupand found again evidence for co-rotation within a planar structure of dwarfgalaxies, posing a challenge to the current LambdaCDM paradigm. To furtherstudy the distribution of satellite systems around other galaxy groups, we havetested MTO - a program to detect astronomical sources - and found that it workswell in combination with surface brightness fluctuation distance measurementsto get a complete sample of dwarf galaxies. Such an approach will improve thecensus of dwarf galaxies in nearby galaxy groups, bringing the study of thesmall-scale problems to a solid statistical foundation.
