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 […]
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. […]
Kavli Affiliate: J. Todd Hoeksema | First 5 Authors: Alexander Kosovichev, Sarbani Basu, Yuto Bekki, Juan Camilo Buitrago-Casas, Theodosios Chatzistergos | Summary: High-resolution helioseismology observations with the Helioseismic and Magnetic Imager (HMI) onboard Solar Dynamics Observatory (SDO) provide a unique three-dimensional view of the solar interior structure and dynamics, revealing a tremendous complexity of the […]
Kavli Affiliate: Philip H. Scherrer | First 5 Authors: Alexander Kosovichev, Sarbani Basu, Yuto Bekki, Juan Camilo Buitrago-Casas, Theodosios Chatzistergos | Summary: High-resolution helioseismology observations with the Helioseismic and Magnetic Imager (HMI) onboard Solar Dynamics Observatory (SDO) provide a unique three-dimensional view of the solar interior structure and dynamics, revealing a tremendous complexity of the […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: The Pan-Experiment Galactic Science Group, :, Julian Borrill, Susan E. Clark, Jacques Delabrouille | Summary: Polarized foreground emission from the Galaxy is one of the biggest challenges facing current and upcoming cosmic microwave background (CMB) polarization experiments. We develop new models of polarized Galactic dust and […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Christopher C. Stark, Sarah Steiger, Armen Tokadjian, Dmitry Savransky, Rus Belikov | Summary: Estimating the exoplanet scientific productivity of the Habitable Worlds Observatory requires estimating science exposure times. From exoplanet yields to spectral retrievals, exposure times are at the heart of our understanding of the capabilities of […]
Kavli Affiliate: Eric Charles | First 5 Authors: Tom Shutt, Bahrudin Trbalic, Eric Charles, Niccolo Di Lalla, Oliver Hitchcock | Summary: We present GammaTPC, a transformative 0.1-10 MeV $gamma$-ray instrument concept featuring a tracker using a liquid argon time projection chamber (LAr TPC) technology with the novel GAMPix high spatial resolution and ultra low power […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Samuel V. Hull, Joseph S. Adams, Simon R. Bandler, Matthew Cherry, James A. Chervenak | Summary: Microcalorimeter instruments aboard future X-ray observatories will require an anti-coincidence (anti-co) detector to veto charged particle events and reduce the non-X-ray background. We have developed a large-format, TES-based prototype anti-coincidence detector […]
Kavli Affiliate: Kent Irwin | First 5 Authors: Philippe Peille, Didier Barret, Edoardo Cucchetti, Vincent Albouys, Luigi Piro | Summary: The Athena mission entered a redefinition phase in July 2022, driven by the imperative to reduce the mission cost at completion for the European Space Agency below an acceptable target, while maintaining the flagship nature […]
Kavli Affiliate: Eli S. Rykoff | First 5 Authors: Constantin Payerne, Zhuowen Zhang, Michel Aguena, Céline Combet, Thibault Guillemin | Summary: Cluster scaling relations are key ingredients in cluster abundance-based cosmological studies. In optical cluster cosmology, weak gravitational lensing has proven to be a powerful tool to constrain the cluster mass-richness relation. This work is […]
