Описание: Abstract: We present the Local Group L-band Survey (LGLBS; lglbs.org), a VLA and GBT legacy survey providing the best-possible high-resolution 21-cm HI and 1-2 GHz continuum images of 6 star-forming northern Local Group galaxies (D=0.5-1 Mpc): M31, M33, NGC6822, IC10, IC1613, and WLM. The high sensitivity and spatial resolution in these key ISM and star formation tracers coupled with a complete external view of our neighboring galaxies offers new insights into major questions: how much cold, dense atomic gas exists in galaxies? How does it relate to molecular gas and star formation? How do supernovae couple to the ISM? What drives interstellar turbulence? I will present initial LGLBS results towards answering these open questions and how LGLBS demonstrates the incredible the incredible promise for the ngVLA and SKA to expand these studies across the complete nearby star-forming galaxy population.
