Wide-Field Survey of Dwarf Satellite Systems Around 10 Hosts in the Local Volume

Understand

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.
