Dark Energy Survey: Modeling strategy for multiprobe cluster cosmology and validation for the Full Six-year Dataset

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Chun-Hao To, Elisabeth Krause, Chihway Chang, Hao-Yi Wu, Risa H. Wechsler | Summary: We introduce an updated To&Krause2021 model for joint analyses of cluster abundances and large-scale two-point correlations of weak lensing and galaxy and cluster clustering (termed CL+3x2pt analysis) and validate that this model meets […]

A Hierarchical Shock Model of Ultra-High-Energy Cosmic Rays

Kavli Affiliate: Roger Blandford | First 5 Authors: Paul Simeon, Noémie Globus, Kirk S. S. Barrow, Roger Blandford, | Summary: We propose that a hierarchical shock model$unicode{x2014}$including supernova remnant shocks, galactic wind termination shocks, and accretion shocks around cosmic filaments and galaxy clusters$unicode{x2014}$can naturally explain the cosmic ray spectrum from ~1 GeV up to ~200 […]

Hints of Primordial Magnetic Fields at Recombination and Implications for the Hubble Tension

Kavli Affiliate: Tom Abel | First 5 Authors: Karsten Jedamzik, Levon Pogosian, Tom Abel, , | Summary: Primordial Magnetic Fields (PMFs), long studied as potential relics of the early Universe, accelerate the recombination process and have been proposed as a possible way to relieve the Hubble tension. However, previous studies relied on simplified toy models. […]
