## Key points

- A new window of millimeter-wave observations spanning frequency bands from 30 to 500 GHz is proposed.
- The survey would cover half the sky and be an order of magnitude deeper (about 0.5 uK-arcmin) and higher-resolution (about 10 arcseconds) than currently funded surveys.
- The survey could provide major advances in measuring the distribution of dark matter and gas on small scales, which is crucial for understanding galaxy evolution and large-scale structure formation.
- The survey could yield insight on important topics including dark matter particle properties, new light particle species, the epoch of inflation, and the census of bodies orbiting in the outer Solar System.
- A diverse group of experts from various fields are involved in this project.
- The survey has enormous potential to advance our understanding not only fundamental physics but also astrophysics.

## Summary

A new window of millimeter-wave observations that span frequency bands in the range of 30 to 500 GHz, survey half the sky, and are both an order of magnitude deeper (about 0.5 uK-arcmin) and of higher-resolution (about 10 arcseconds) than currently funded surveys would yield an enormous gain in understanding of both fundamental physics and astrophysics. This opportunity could provide major advances in measuring the distribution of dark matter and gas on small-scales, which is crucial for understanding the evolution of galaxies and large-scale structure formation. Additionally, this survey could yield needed insight on several important topics including dark matter particle properties, new light particle species, the epoch of inflation, and the census of bodies orbiting in the outer Solar System. The proposed ultra-deep, high-resolution millimeter-wave survey has attracted a diverse group of experts from various fields including Neelima Sehgal, Ho Nam Nguyen, Joel Meyers, Moritz Munchmeyer, Tony Mroczkowski, Luca Di Mascolo, Eric Baxter, Francis-Yan Cyr-Racine , Mathew Madhavacheril , Benjamin Beringue , Gil Holder , Daisuke Nagai , Simon Dicker , Cora Dvorkin , Simone Ferraro , George M.

The survey would provide a unique opportunity to study the properties of dark matter particles and their distribution on small scales - information that is essential for understanding the nature of dark matter and its role in galaxy formation and evolution. Additionally, this millimeter wave survey could also help uncover clues about new light particle species that may exist in our universe as well as shed light on the epoch of inflation - a period when our universe underwent rapid expansion shortly after the Big Bang by studying cosmic microwave background radiation at high resolution levels with greater sensitivity than ever before possible . Furthermore this survey could also help us better understand our own Solar System by providing a more accurate census of bodies orbiting in its outer reaches - information which will be invaluable for future space exploration missions . Overall an ultra deep high resolution millimeter wave survey has enormous potential to advance our understanding not only fundamental physics but also astrophysics with a diverse group experts from various fields working together on this project we can expect exciting discoveries that will shape our understanding universe for years come .
