Non-linear damping of superimposed primordial oscillations on the matter power spectrum in galaxy surveys
Mario Ballardini, Riccardo Murgia, Marco Baldi +2
Galaxy surveys are an important probe for superimposed oscillations on the primordial power spectrum of curvature perturbations, which are predicted in several theoretical models o…
Measuring lensing ratios with future cosmological surveys
José Ramón Bermejo-Climent, Mario Ballardini, Fabio Finelli +1
The ratio between the CMB lensing/galaxy counts and the galaxy shear/galaxy counts cross-correlations combines the information from different cosmological probes to infer cosmograp…
Energy-momentum tensor and helicity for gauge fields coupled to a pseudo-scalar inflaton
M. Ballardini, M. Braglia, F. Finelli +2
We study the energy-momentum tensor and helicity of gauge fields coupled through to a pseudo-scalar field driving inflation. Under the assumption of a consta…
ATLAS Probe: Breakthrough Science of Galaxy Evolution, Cosmology, Milky Way, and the Solar System
Yun Wang, Mark Dickinson, Lynne Hillenbrand +45
ATLAS (Astrophysics Telescope for Large Area Spectroscopy) is a concept for a NASA probe-class space mission. It is the spectroscopic follow-up mission to WFIRST, boosting its scie…
Constraining primordial non-Gaussianity using two galaxy surveys and CMB lensing
Mario Ballardini, William Luke Matthewson, Roy Maartens
Next-generation galaxy surveys will be able to measure perturbations on scales beyond the equality scale. On these ultra-large scales, primordial non-Gaussianity leaves signatures…
Planck 2018 results. VII. Isotropy and Statistics of the CMB
Planck Collaboration, Y. Akrami, M. Ashdown +147
Analysis of the Planck 2018 data set indicates that the statistical properties of the cosmic microwave background (CMB) temperature anisotropies are in excellent agreement with pre…
