Title: A Northern Hunt for Local Dwarf Galaxies
Abstract:
Dwarf galaxies are central to theories of galaxy formation,
contributing directly to knowledge on: the distribution and nature of
dark matter; the processes of star formation; and the origin and growth
of large-scale structure. Extremely low-luminosity dwarfs are only
detectable at very short distances, within or near the Local Group, so
very few are known. The first part (southern hemisphere) of an all-sky
survey to discover more has resulted in one certain and one borderline
new Local Group dwarf, plus a number of more distant dwarfs and low
surface brightness galaxies. Extending this survey to the northern
hemisphere, we have produced a list of approximately one hundred dwarf
galaxy candidates. We propose to continue (and, if possible, complete)
follow-up imaging of these to determine their nature.
