Kavli Affiliate: Roberto Maiolino | Summary:The period between z ~ 3-6, a key transformational phase in galaxy evolution preceding ‘cosmic noon’ (z ~ 1-3), is very poorly explored in terms of feedback from AGN acting through gas outflows. In this work, we study the properties of outflows in AGN (mostly X-ray-selected) from the GOODS-S field, […]

Kavli Affiliate: George Efstathiou | Summary:Cosmology from weak gravitational lensing has been limited by astrophysical uncertainties in baryonic feedback and intrinsic alignments. By calibrating these effects using external data, we recover non-linear information, achieving a 2% constraint on the clustering amplitude, $S_8$, resulting in a factor of two improvement on the $Λ$CDM constraints relative to […]

Kavli Affiliate: Ulrich Sperhake | Summary:We study the scattering of boson-star binaries, taking into account three effects: point-mass gravitational, tidal, and short-range scalar-field interactions. We compare analytic results to the scattering angle extracted from four sequences of numerical-relativity simulations at fixed energy and varying impact parameter. The very good agreement exhibits the attractive (repulsive) effect […]

Kavli Affiliate: Anthony Challinor | Summary:Large-scale $B$-mode polarization of the cosmic microwave background (CMB) is a prime target for current and future experiments in search of primordial gravitational waves (PGW). With increasingly sensitive instruments being deployed, secondary $B$-modes induced by the weak gravitational lensing of CMB photons are becoming an important limitation and need to […]

Kavli Affiliate: George Efstathiou | Summary:We report the first upper limits on the power spectrum of 21-cm fluctuations during the Epoch of Reionization and Cosmic Dawn from Phase II of the Hydrogen Epoch of Reionization Array (HERA) experiment. HERA Phase II constitutes several significant improvements in the signal chain compared to Phase I, most notably […]

Kavli Affiliate: E. P. S. Shellard | Summary:The search for primordial non-Gaussianities (PNG) is theoretically well motivated but remains observationally challenging. Tight constraints with low significance for the standard non-Gaussian shapes suggest that detection may lie beyond the reach of near-future experiments. However, tests of PNG are highly template-dependent. From a theory perspective, a whole […]

Kavli Affiliate: Blake Sherwin | Summary:Over the last year, kinematic Sunyaev–Zel’dovich (kSZ) velocity reconstruction — the measurement of the large-scale velocity field using the anisotropic statistics of the small-scale kSZ-galaxy overdensity correlation — has emerged as a statistically significant probe of the large-scale Universe. In this work, we perform a 2-dimensional tomographic reconstruction using ACT […]

Kavli Affiliate: A. C. Davis| First 5 Authors: S. Al Kharusi, S. Al Kharusi, , , | Summary:EXO-200 was a leading double beta decay experiment consisting of a single-phase, enriched liquid xenon time projection chamber filled with an admixture of 80.672% $^136$Xe and 19.098% $^134$Xe. The detector operated at WIPP between 2010 and 2018 and […]
