We present the results of an extensive search for dwarf satellite galaxies around 10 primary host galaxies in the Local Volume ( D < 12 Mpc ) using archival CFHT/MegaCam imaging data .
The hosts span a wide range in properties , with stellar masses ranging from that of the LMC to { \sim } 3 times that of the Milky Way ( MW ) .
The surveyed hosts are : NGC 1023 , NGC 1156 , NGC 2903 , NGC 4258 , NGC 4565 , NGC 4631 , NGC 5023 , M51 , M64 , and M104 .
We detect satellite candidates using a consistent semi-automated detection algorithm that is optimized for the detection of low surface brightness objects .
Depending on the host , our completeness limit is M _ { g } { \sim } -8 to -10 ( assuming the distance of the host ) .
We detect objects with surface brightness down to \mu _ { 0 ,g } { \sim } 26 mag arcsec ^ { -2 } at \gtrsim 90 \% completeness .
The survey areas of the six best-surveyed hosts cover most of the inner projected R < 150 kpc area , which roughly doubles the number of MW-mass hosts surveyed at this level of area and luminosity completeness .
The number of detected candidates range from 1 around M64 to 33 around NGC 4258 .
In total , 153 candidates are found , of which 93 are new .
While we defer an analysis of the satellite luminosity functions of the hosts until distance information is available for the candidates , we do show that the candidates are primarily red , spheroid systems with properties roughly consistent with known satellites in the Local Group .
