Beyond the traditional Line-of-Sight approach of cosmological angular statistics
Nils Schöneberg, Marko Simonović, Julien Lesgourgues +1
We present a new efficient method to compute the angular power spectra of large-scale structure observables that circumvents the numerical integration over Bessel functions, expand…
Noise-tolerant Detection of Topological Orders in Quantum Many-body States
Xi Chen, Shi-ju Ran, Shuo Yang +2
Topologically ordered states are fundamentally important in theoretical physics, which are also suggested as promising candidates to build fault-tolerant quantum devices. However,…
Planck 2018 results. X. Constraints on inflation
Planck Collaboration, Y. Akrami, F. Arroja +173
We report on the implications for cosmic inflation of the 2018 Release of the Planck CMB anisotropy measurements. The results are fully consistent with the two previous Planck cosm…
Planck 2018 results. VI. Cosmological parameters
Planck Collaboration, N. Aghanim, Y. Akrami +179
We present cosmological parameter results from the final full-mission Planck measurements of the CMB anisotropies. We find good consistency with the standard spatially-flat 6-param…
Planck 2018 results. I. Overview and the cosmological legacy of Planck
Planck Collaboration, Y. Akrami, F. Arroja +188
The European Space Agency's Planck satellite, which was dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave…
MontePython 3: boosted MCMC sampler and other features
Thejs Brinckmann, Julien Lesgourgues
MontePython is a parameter inference package for cosmology. We present the latest development of the code over the past couple of years. We explain, in particular, two new ingredie…
Exotic energy injection with ExoCLASS: Application to the Higgs portal model and evaporating black holes
Patrick Stöcker, Michael Krämer, Julien Lesgourgues +1
We devise a new user-friendly tool interfaced with the Boltzmann code CLASS to deal with any kind of exotic electromagnetic energy injection in the universe and its impact on aniso…
Cosmology in the era of Euclid and the Square Kilometre Array
Tim Sprenger, Maria Archidiacono, Thejs Brinckmann +2
Theoretical uncertainties on non-linear scales are among the main obstacles to exploit the sensitivity of forthcoming galaxy and hydrogen surveys like Euclid or the Square Kilometr…
