Because they are dark-matter dominated, dwarf galaxies provide some of the most stringent tests of our cold dark matter model. Specifically, Lambda CDM makes predictions about the number, shape, and spatial distributions of the faint friends of massive galaxies. I will present results from the Exploration of Local VolumE Satellites (ELVES) survey, that constructs the largest known sample of satellites around Milky Way-like hosts. I will discuss the radial profiles, mass-size relations, and quenched fractions of the ELVES satellites. For the second half, I will turn to what we know about black holes in dwarf galaxies, and how their demographics sheds light on the formation of the seeds of supermassive black holes. |
