We have now transformational facilities capable of producing high resolution and high-quality imaging and spectroscopy at mm to submm wavelengths (ALMA), and in the near and mid IR (JWST), which are presently driving our understanding of how stars, black holes, and galaxies grow. In parallel, new breakthrough facilities at longer radio wavelengths are starting operation, being constructed, or in advanced planning (MeerKAT, ASKAP, SKA, ngVLA). These new facilities enable large systematic surveys and will produce copious very high sensitivity and resolution observations at cm to millimeter wavelengths enabling a new view of the gas phase and its processes through continuum, atomic, and molecular transitions.

This meeting will explore how the work taking place at existing facilities is shaping our understanding of the interstellar medium structure and feedback in our own Milky Way and external galaxies, and how this work is re-framing the science that will be addressed by the remarkable capabilities of future radio observatories. This will be a forward-looking meeting: we ask all speakers to articulate the impact of the newly gained knowledge from JWST, ALMA, MeerKAT, and ASKAP data on the science that SKA and ngVLA will address.
