Web2.2. Extended Cosmologies. Due to the significant non-Gaussian information in the matter PDF and the success of this LDT formalism in CDM, we modify this framework to … Web1 dag geleden · Exploring Mirror Twin Higgs Cosmology with Present and Future Weak Lensing Surveys. We explore the potential of precision cosmological data to study non-minimal dark sectors by updating the cosmological constraint on the mirror twin Higgs model (MTH). The MTH model addresses the Higgs little hierarchy problem by …

Web15 mrt. 2024 · Dark matter interactions with electrons or protons during the early Universe leave imprints on the cosmic microwave background and the matter power spectrum, and can be probed through cosmological and astrophysical observations. These interactions lead to momentum and heat exchange between the ordinary and dark matter … Web1 mei 2024 · For the matter power spectrum, these assumptions mean that the matter power spectrum is only accurate to within a factor of 2 compared to that measured from numerical simulations (Mead et al. 2015). It is possible to go beyond these simplistic assumptions, and we direct the interested reader to Cooray & Sheth ( 2002 ), Smith et al. … merced county school district calendar

Web18 jun. 2014 · Using modified Richardson-Lucy algorithm we reconstruct the primordial power spectrum (PPS) from Planck Cosmic Microwave Background (CMB) temperature anisotropy data. In our analysis we use different combinations of angular power spectra from Planck to reconstruct the shape of the primordial power spectrum and locate … Webdramatically reduces nonlinearities in both the covariance and the shape of the power spectrum. Here, analyzing Coyote Universe real-space dark-matter density fields, we … WebThe lensed power spectrum functions are not intended to replace those calculated by default when getting CAMB results, but may be useful for tests, e.g. using different lensing potential power spectra, partially-delensed lensing power spectra, etc. merced county rules and regulations
