Lattice formulation of axion inflation. Application to preheating
Jose Roberto Canivete Cuissa, Daniel G. Figueroa
We present a lattice formulation of an interaction between an axion and some gauge sector with the following properties: it reproduces the continuum th…
Observable tests of self-interacting dark matter in galaxy clusters: BCG wobbles in a constant density core
David Harvey, Andrew Robertson, Richard Massey +1
Models of Cold Dark Matter predict that the distribution of dark matter in galaxy clusters should be cuspy, centrally concentrated. Constant density cores would be strong evidence…
Core Cosmology Library: Precision Cosmological Predictions for LSST
Nora Elisa Chisari, David Alonso, Elisabeth Krause +27
The Core Cosmology Library (CCL) provides routines to compute basic cosmological observables to a high degree of accuracy, which have been verified with an extensive suite of valid…
Constraining the photon coupling of ultra-light dark-matter axion-like particles by polarization variations of parsec-scale jets in active galaxies
M. M. Ivanov, Y. Y. Kovalev, M. L. Lister +4
Ultra-light dark matter may consist of axion-like particles with masses below 10^(-19) eV. Two-photon interactions of these particles affect the polarization of radiation propagati…
Non-perturbative probability distribution function for cosmological counts in cells
Mikhail M. Ivanov, Alexander A. Kaurov, Sergey Sibiryakov
We present a non-perturbative calculation of the 1-point probability distribution function (PDF) for the spherically-averaged matter density field. The PDF is represented as a path…
Dark Energy Survey Year 1 Results: Constraints on Intrinsic Alignments and their Colour Dependence from Galaxy Clustering and Weak Lensing
S. Samuroff, J. Blazek, M. A. Troxel +70
We perform a joint analysis of intrinsic alignments and cosmology using tomographic weak lensing, galaxy clustering and galaxy-galaxy lensing measurements from Year 1 (Y1) of the D…
