GBT HI follow-up observations for THOR-GC
Abstract
Based on the success of the THOR survey (The HI, OH, Recombination Line survey of the Milky Way; Beuther et al., 2016), we conducted an extension of THOR with the VLA to the Galactic Center (THOR-GC; 18 deg > l > -6 deg, |b| <= 1.25 deg) to study the interstellar medium and star formation in the extreme conditions of the Galactic Center. In particular, we measured the HI 21 cm line to address physical properties and dynamics of the atomic gas. Here, we propose GBT HI observations to obtain short-spacing information for this successfully observed VLA project THOR-GC (Project ID: 20A-160). The large longitude coverage enables studies of gas flows from the Galactic bar region to the central molecular zone. In combination with recent CO surveys (e.g., the SEDIGISM survey) and simulations, we will study the formation of molecular clouds and effects of stellar feedback.
