The Inner Galaxy ALFA (I-GALFA) Low-Latitude HI Survey

We propose to map the whole inner Galactic plane visible from Arecibo to |b| 10 in HI 21-cm line emission using ALFA. A few G-ALFA pro jects have begun mapping small low-latitude regions in different ways, but now that the observational techniques have been demonstrated, it is time for a more systematic approach that will serve the whole astronomical community. Our proposed map area is 1078 square degrees. The survey will have an integration time of 4.1s per Nyquist pixel (1.8 в 1.8 ) and will require 129 days. This pro ject will produce data that is essential for addressing all of the HI low-latitude studies listed in the GALFA White Paper. The extensive latitude coverage of the survey will reveal the full structures of chimneys/worms and significantly expand the catalog of halo clouds, both of which are essential for understanding the disk-halo connection. The observations are commensally paired with a Zone of Avoidance (ZOA) proposal (Henning et al.) to search the same area with the WAPPS for HI galaxies hidden behind the Milky Way.
