The HI Nearby Galaxy Survey (THINGS) is a high-spectral and spatial resolution survey of HI emission in 34 nearby galaxies, conducted using the NRAO Very Large Array (VLA). The primary scientific goal is to investigate fundamental characteristics of the interstellar medium (ISM) related to galaxy morphology, star formation, and mass distribution across the Hubble sequence. The THINGS database features homogeneous sensitivity and spatial and velocity resolution, which is at the limit of what can be achieved with the VLA for a significant number of galaxies. The sample includes galaxies at distances of 2 to 15 Mpc, covering a wide range of star formation rates, total HI masses, absolute luminosities, and metallicities. The survey aims to provide detailed insights into the small-scale structure of the ISM, dark matter distribution, and processes leading to star formation. The THINGS data products, including channel maps, integrated HI maps, velocity fields, and velocity dispersion maps, are publicly available and have been used in various companion papers to address specific scientific questions.The HI Nearby Galaxy Survey (THINGS) is a high-spectral and spatial resolution survey of HI emission in 34 nearby galaxies, conducted using the NRAO Very Large Array (VLA).
