Abstract: The advent of deep and wide optical imaging surveys like the Hyper-Suprime Camera (HSC) Survey, and eventually LSST, are illuminating the low surface brightness univers. I will describe our efforts to determine the space density of low-mass galaxies, including the lowest surface brightness population. Then I will show how surface brightness fluctuations may revolutionize our understanding of dwarf satellite populations, and thus our tests of cold dark matter predictions. Finally, I will describe our ongoing efforts to quantify the massive black hole population in present-day low-mass galaxies, with the hope of understanding the first black hole seeds.
