Snowmass 21 planning Underway, Including PCOS-related Science

27 July 2020

Over the next year, the US particle physics community will engage in Snowmass 2021 to define the most important questions for p

article physics and to identify the most promising opportunities to address these questions in a global context. In this sense, Snowmass is t

he particle-physics equivalent to the National Academies’ Decadal Survey on Astronomy and Astrophysics.

The overall effort consists of 10 Frontier Fields, each containing several topical groups. Some topical groups relating to PCOS science are:

CF1. Dark Matter: Particle-like
CF3. Dark Matter: Cosmic Probes
CF4. Dark Energy and Cosmic Acceleration: The Modern Universe
CF7. Cosmic Probes of Fundamental Physics
TF9. Astro-particle physics and cosmology

Each group will organize workshops on its theme of study, which will form the basis of their recommendation to the Particle Physics Project Prioritization Panel (P5). Interested parties can contribute to these workshops, accessing connection details and presentation slides through the individual topical group pages linked above. These will form the roots of the entire effort that will be based on a series of preparatory meetings organized by Snowmass conveners, starting with a Snowmass Planning Meeting: four days during the week of 5 October 2020, followed by the Snowmass Mid-term Assessment during the 2021 APS April Meeting, and ending with the Snowmass Summer Study from 11-20 July 2021 at UW Seattle.

NASA's Chandra, Webb Combine for Arresting Views

Four composite images deliver dazzling views from NASA's Chandra X-ray Observatory and James Webb Space Telescope of two galaxies, a nebula, and a star cluster. These cosmic wonders and details are made available by mapping the data to colors that humans can perceive. Read more.
