Map centered on M101 (center box) of the projected positions of associated galaxies in a ∼400 × 400 kpc field. The confirmed M101 dwarf satellites are shown as blue stars. The kernel density estimate of the satellites is shown as the blue to white contour. The candidate dwarf galaxies discovered in this work are highlighted as the red stars. The virial radius of M101, ∼250 kpc, is displayed as the blue dotted circle surrounding M101. Unrelated background galaxies from P. Bennet et al. (2017, 2019) are not shown. The virial radius of NGC 5585 (dotted gray circle) is estimated based on its mass (L. C. Hunter et al. 2025).
