Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Davide Racco, , , | Summary: The QCD axion has important connections to early universe cosmology. For example, it is often said that isocurvature limits rule out a combination of high axion decay constant, $f_a$, and high inflationary Hubble scale, $H_I$. High scales […]
Kavli Affiliate: Kiyoshi Masui | Summary:The dispersion measure (DM) of fast radio bursts (FRBs) in conjunction with their redshifts can be used as powerful probes of the distribution of extragalactic plasma. With a large enough sample, the free-electron–galaxy power spectrum $P_eg$ can be measured by cross-correlating FRB DMs with galaxy positions. However, a precise measurement […]
Kavli Affiliate: Martin Haehnelt | Summary:Dwarf galaxies provide powerful laboratories for studying galaxy formation physics. Their early assembly, shallow gravitational potentials, and bursty, clustered star formation histories make them especially sensitive to the processes that regulate baryons through multi-phase outflows. Using high-resolution, cosmological zoom-in simulations of a dwarf galaxy from textitthe Pandora suite, we explore […]
Kavli Affiliate: Oskar Painter | Summary:We propose a cavity-mediated gate between two transmon qubits or other nonlinear superconducting elements. The gate is realized by driving both qubits at a frequency that is near-resonant with the frequency of the cavity. Since both qubits are subject to a cross-resonant drive, we call this gate a cross-cross-resonance gate. […]

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Daichi Kashino, Simon J. Lilly, Jorryt Matthee, Ruari Mackenzie, Anna-Christina Eilers | Summary: We present a comprehensive analysis of the relationship between galaxies and the intergalactic medium (IGM) during the late stages of cosmic reionization, based on the complete JWST EIGER dataset. Using deep NIRCam $3.5,mathrm{mu […]
Kavli Affiliate: Joshua Frieman | Summary:We present cosmological constraints from 8 strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar velocity dispersions measured from spectra obtained with the James Webb Space Telescope (JWST), the Keck Telescopes, and the Very Large Telescope (VLT), utilizing improved methods. We used […]
