What is a Galaxy? In the past six years, more than two dozen dwarf galaxies have been
discovered around the Milky Way and M31. Many of these discoveries
are 100 times less luminous than any galaxy previously known, and a
million times less luminous than the Milky Way itself. These
discoveries hint that "ultra-faint" galaxies are the most numerous
type of galaxy in the universe. The Milky Way's ultra-faint dwarf
population is currently also our best tracer of dark matter on
subgalactic scales, making a well-defined census and study of these
objects a fundamental test for cold dark matter models on such scales.
This talk will highlight i. the properties of the few Milky Way
companions with only one ten-millionth of the Milky Way's own
luminosity, ii. the brewing controversy of the definition of the term
"galaxy", and iii. prospects and challenges for this field in imminent
and future surveys. Haverford College host: TBD |
