Caption: Figure 15.

Magnified view of a stacked g-band NGVS image showing a 10′ × 10′ region located in the Virgo cluster core. This field is located approximately 40′ (~200 kpc) to the northwest of M87. Two early-type dwarf galaxies from the VCC of Binggeli et al. (1985) are shown by the cyan ellipses: VCC1129 and VCC1104 ( g ≈ 17.7 mag and 15.4 mag, respectively). The yellow ellipses show a number of faint, low surface brightness dwarfs that are probable cluster members based on sizes, surface brightness, and colors; the small galaxy to the southeast of VCC1129 (also detected by Lieder et al. 2012) has in fact recently been spectroscopically confirmed as a cluster member by our team. These newly discovered galaxies have magnitudes in the range 18.7 mag < g < 24.9 mag and effective surface brightnesses of 24.3 mag arcsec ⁻² < lang μ _g rang _e < 28.8 mag arcsec ⁻².
