A novel, fast, and accurate code for cosmological loop calculations
Tjark Harder, Luca Amendola, Thiago S. Pereira +1
We introduce neckar, a public code for the one-loop matter and galaxy power spectrum, as well as correlation function, in the Eulerian Effective Field Theory of Large-Scale Structu…
Spatial anisotropies from long wavelength scalar and tensor modes
Jorge Noreña, Thiago S. Pereira, Sean K. Reynolds
We investigate the dominant physical effects of superhorizon fluctuations in a flat FLRW universe, focusing on whether the combined evolution of scalar and tensor adiabatic modes i…
Fréchet Vectors as sensitive tools for blind tests of CMB anomalies
Ricardo G. Rodrigues, Thiago S. Pereira, Miguel Quartin
Cosmological data collected on a sphere, such as CMB anisotropies, are typically represented by the spherical harmonic coefficients, denoted as . The angular power spec…
Multifield curved solid: Early dark energy and perturbation instabilities
Juan P. Beltrán Almeida, Alejandro Guarnizo, Thiago S. Pereira +1
We introduce a multifield dark energy model with a nonflat field-space metric, in which one field is dynamical while the others have constant spatial gradients. The model is predic…
