Symbolic Implementation of Extensions of the Boltzmann Solver
Beatrice Moser, Christiane S. Lorenz, Uwe Schmitt +5
is a Python-based framework for the fast computation of cosmological model predictions. One of its core features is the symbolic representation of the Einstein-B…
Combined -point analysis of the Cosmic Microwave Background and Large-Scale Structure: implications for the -tension and neutrino mass constraints
Raphael Sgier, Christiane Lorenz, Alexandre Refregier +3
We present cosmological constraints for the flat CDM model, including the sum of neutrino masses, by performing a multi-probe analysis of a total of 13 tomographic auto- and cro…
Reconstruction of the neutrino mass as a function of redshift
Christiane S. Lorenz, Lena Funcke, Matthias Löffler +1
We reconstruct the neutrino mass as a function of redshift, z, from current cosmological data using both standard binned priors and linear spline priors with variable knots. Using…
Time-varying neutrino mass from a supercooled phase transition: current cosmological constraints and impact on the - plane
Christiane S. Lorenz, Lena Funcke, Erminia Calabrese +1
In this paper we investigate a time-varying neutrino mass model, motivated by the mild tension between cosmic microwave background (CMB) measurements of the matter fluctuations and…
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…
The impact of relativistic effects on cosmological parameter estimation
Christiane S. Lorenz, David Alonso, Pedro G. Ferreira
Future surveys will access large volumes of space and hence very long wavelength fluctuations of the matter density and gravitational field. It has been argued that the set of seco…
Distinguishing between Neutrinos and time-varying Dark Energy through Cosmic Time
Christiane S. Lorenz, Erminia Calabrese, David Alonso
We study the correlations between parameters characterizing neutrino physics and the evolution of dark energy. Using a fluid approach, we show that time-varying dark energy models…
