The cycle of interstellar matter in the Milky Way as revealed by The HI/OH/Recombination-line (THOR) survey
The past decade has witnessed a large number of Galactic plane surveys at angular resolutions below 20 arcseconds. However, no comparable high-resolution survey existed at long radio wavelengths, around 21 cm in line and continuum emission. We remedied this situation by studying the northern Galactic plane at 20-arcsecond resolution in the emission of atomic, molecular, and ionized gas. Employing the Karl G. Jansky Very Large Array (VLA) in the C-array configuration, we observed the atomic hydrogen (HI) emission at 21 cm, four OH lines, nineteen Hn radio recombination lines, and the continuum emission from 1 to 2 GHz in full polarization toward the first Galactic quadrant.
I will summarize the results of the analysis of this survey and present the main data products, which are publicly available to the astronomical community.
