Kavli Affiliate: Keith Thompson | Summary:LiteBIRD is a JAXA-led strategic large-class satellite mission designed to measure the polarization of the cosmic microwave background and Galactic foregrounds from 34 to 448 GHz across the entire sky from L2 in the late 2020s. The scientific payload includes three telescopes which are called the low-, mid-, and high-frequency […]
Kavli Affiliate: Seth Digel | Summary:The mechanism(s) driving the early- and late-time accelerated expansion of the Universe represent one of the most compelling mysteries in fundamental physics today. The path to understanding the causes of early- and late-time acceleration depends on fully leveraging ongoing surveys, developing and demonstrating new technologies, and constructing and operating new […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Alex Drlica-Wagner, Chanda Prescod-Weinstein, Hai-Bo Yu, Andrea Albert, Arka Banerjee | Summary: Cosmological and astrophysical observations currently provide the the only robust, positive evidence for dark matter. Cosmic probes of dark matter, which seek to determine the fundamental properties of dark matter through observations of the […]

Kavli Affiliate: Daniel Akerib | Summary:This report summarizes the findings of the CF1 Topical Subgroup to Snowmass 2021, which was focused on particle dark matter. One of the most important scientific goals of the next decade is to reveal the nature of dark matter (DM). To accomplish this goal, we must delve deep, to cover […]

Kavli Affiliate: Grzegorz M. Madejski | First 5 Authors: Ioannis Liodakis, Alan P. Marscher, Iván Agudo, Andrei V. Berdyugin, Maria I. Bernardos | Summary: Blazars are active galactic nuclei that launch collimated, powerful jets of magnetized relativistic plasma. Their primary jet, whose emission typically spans from low-frequency radio to very high-energy ($gtrsim0.1$ TeV) $gamma$-rays (Blandford […]
Kavli Affiliate: Grzegorz Madejski | Summary:Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point nearly along the line of sight, is produced by high-energy particles, up to $sim 1$ TeV. Although the jets are known to be ultimately powered by a supermassive black hole, how the particles are […]
