The 11MPC Hα and Ultraviolet Galaxy Survey
Abstract
We introduce 11HUGS (11Mpc Hα and Ultraviolet Galaxy Survey), an outgrowth of the recently completed 11MPC Survey, a ground-based Hα and Rband imaging program of a volume-limited sample of 367 spiral and irregular galaxies within a distance of 11 Mpc. As such, the 11HUGS galaxies area complete subset of the 11MPC Survey catalog which avoid the Galactic plane (|b| > 30.) and are observable by GALEX. The goal of 11HUGS is to characterize the demographics and star formation properties of nearby galaxies, with an emphasis on the dwarf galaxies which dominate the sample population. The data also provide a foundation for follow-up studies of the HII region populations, star formation, chemical abundance, and ISM properties of the galaxy sample. The combination of Hα imaging, which provides snapshots of the ongoing star formation, and UV imaging, which traces star formation over a much longer timescale, will yield powerful constraints on the systematic errors in the inferred star formation related quantities.
