11HUGS (11Mpc Hα and Ultraviolet Galaxy Survey) is obtaining deep ultraviolet images for a complete sample of spiral and irregular galaxies in the 11Mpc local volume. This poster describes the ongoing GALEX Legacy UV survey component, while a companion poster describes the recently completed ground-based Hα and R-band imaging.
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.
We introduce the 11HUGS Legacy program, by presenting early images and describing the science issues that we plan to address. 11HUGS is designed to complement the GANGS (GALEX Nearby Galaxy Survey) UV imaging of galaxies within a distance of 11Mpc. When our observations of 101 galaxies are combined with GANGS imaging of 116 other galaxies (mostly more luminous spirals) in this volume, the dataset will be a well-defined and fully representative sample of late-type galaxies within 11Mpc, a true Legacy for the GALEX mission.
