Discrepancies between CFHTLenS cosmic shear and Planck: new physics or systematic effects? [PDF]
, 2016 There is currently a discrepancy in the measured value of the amplitude of matter clustering, parameterised using $\sigma_8$, inferred from galaxy weak lensing, and cosmic microwave background data, which could be an indication of new physics, such as ...

Gravitational waves from current-carrying cosmic strings [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 Cosmic strings are predicted by many Standard Model extensions involving the cosmological breaking of a symmetry with nontrivial first homotopy group and represent a potential source of primordial gravitational waves (GWs).

Propagation of Cosmic Rays: Nuclear Physics in Cosmic-Ray Studies [PDF]
AIP Conference Proceedings, 2005 The nuclei fraction in cosmic rays (CR) far exceeds the fraction of other CR species, such as antiprotons, electrons, and positrons. Thus the majority of information obtained from CR studies is based on interpretation of isotopic abundances using CR propagation models where the nuclear data and isotopic production cross sections in p- and alpha-induced

Turning AGN Bubbles into Radio Relics with Sloshing: Modeling CR Transport with Realistic Physics
Galaxies, 2021 Radio relics are arc-like synchrotron sources at the periphery of galaxy clusters, produced by cosmic-ray electrons in a μG magnetic field, which are believed to have been (re-)accelerated by merger shock fronts.

Solar and nuclear physics uncertainties in cosmic-ray propagation [PDF]
, 2017 Recent data released by the AMS experiment on the primary spectra and secondary-to-primary ratios in cosmic rays (CRs) can pose tight constraints to astrophysical models of CR acceleration and transport in the Galaxy, thereby providing a robust baseline ...
