Kavli Affiliate: Marcela Carena | First 5 Authors: Tulika Bose, Antonio Boveia, Caterina Doglioni, Simone Pagan Griso, James Hirschauer | Summary: This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More general explorations), and EF10 (Dark Matter at Colliders). […]

Kavli Affiliate: Wayne Hu | First 5 Authors: Lucas F. Secco, Tanvi Karwal, Wayne Hu, Elisabeth Krause, | Summary: We explore a re-parameterization of the lensing amplitude tension between weak lensing (WL) and cosmic microwave background (CMB) data and its implications for a joint resolution with the Hubble tension. Specifically, we focus on the lensing […]

Kavli Affiliate: Daniel Holz | First 5 Authors: Rana X. Adhikari, Luis A. Anchordoqui, Ke Fang, B. S. Sathyaprakash, Kirsten Tollefson | Summary: Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probes give access to fundamental physics not […]

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Christian Pedersen, Andreu Font-Ribera, Nickolay Y. Gnedin, , | Summary: Observations of the Lyman-$alpha$ (Ly$alpha$) forest from spectroscopic surveys such as BOSS/eBOSS, or the ongoing DESI, offer a unique window to study the growth of structure on megaparsec scales. Interpretation of these measurements is a complicated […]

Kavli Affiliate: Clarence L. Chang | First 5 Authors: Clarence L. Chang, Laura Newburgh, Deirdre Shoemaker, Stefan W. Ballmer, Daniel Green | Summary: This report summarizes the envisioned research activities as gathered from the Snowmass 2021 CF5 working group concerning Dark Energy and Cosmic Acceleration: Cosmic Dawn and Before. The scientific goals are to study […]

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, Abigail J. Lee, Kayla Owens, | Summary: We present a new calibration of the J-band absolute magnitude of the JAGB method based on thermally pulsing AGB stars that are members of Milky Way open clusters, having distances and reddenings, independently […]
