EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade
R. Alves Batista, M. A. Amin, G. Barenboim +134
Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the…
The growth of density perturbations in the last 10 billion years from tomographic large-scale structure data
Carlos García-García, Jaime Ruiz Zapatero, David Alonso +5
In order to investigate the origin of the ongoing tension between the amplitude of matter fluctuations measured by weak lensing experiments at low redshifts and the value inferred…
Fully relativistic predictions in Horndeski gravity from standard Newtonian N-body simulations
Guilherme Brando, Kazuya Koyama, David Wands +3
The N-body gauge allows the introduction of relativistic effects in Newtonian cosmological simulations. Here we extend this framework to general Horndeski gravity theories, and inv…
Theoretical priors in scalar-tensor cosmologies: Shift-symmetric Horndeski models
Dina Traykova, Emilio Bellini, Pedro G. Ferreira +3
Attempts at constraining theories of late time accelerated expansion often assume broad priors for the parameters in their phenomenological description. Focusing on shift-symmetric…
