General and consistent statistics for cosmological observations

Ermis Mitsou, Jaiyul Yoo, Ruth Durrer +2

This paper focuses on two aspects of the statistics of cosmological observables that are important for the next stages of precision cosmology. First, we note that the theory of red…

Redshift-space distortions from vector perturbations II: Anisotropic signal

Vittorio Tansella, Camille Bonvin, Giulia Cusin +3

We study the impact on the galaxy correlation function of the presence of a vector component in the tracers' peculiar velocities, in the case in which statistical isotropy is viola…

COFFE: a code for the full-sky relativistic galaxy correlation function

Vittorio Tansella, Goran Jelic-Cizmek, Camille Bonvin +1

We present a public version of the code COFFE (COrrelation Function Full-sky Estimator) available at https://github.com/JCGoran/coffe. The code computes the galaxy two-point correl…

On the feature of the matter two-point function

Vittorio Tansella

We point out the existence of a second feature in the matter two-point function, besides the acoustic peak, due to the baryon-baryon correlation in the early universe and positione…

Detecting higher spin fields through statistical anisotropy in the CMB and galaxy power spectra

Nicola Bartolo, Alex Kehagias, Michele Liguori +3

Primordial inflation may represent the most powerful collider to test high-energy physics models. In this paper we study the impact on the inflationary power spectrum of the comovi…

The full-sky relativistic correlation function and power spectrum of galaxy number counts: I. Theoretical aspects

Vittorio Tansella, Camille Bonvin, Ruth Durrer +2

We derive an exact expression for the correlation function in redshift shells including all the relativistic contributions. This expression, which does not rely on the distant-obse…

Vorticity generation in the Universe: A perturbative approach

Giulia Cusin, Vittorio Tansella, Ruth Durrer

We compute the generation of vorticity from velocity dispersion in the dark matter fluid. For dark matter at zero temperature Helmholtz's theorem dictates that no vorticity is gene…

Lensing signals from Spin-2 perturbations

Julian Adamek, Ruth Durrer, Vittorio Tansella

We compute the angular power spectra of the E-type and B-type lensing potentials for gravitational waves from inflation and for tensor perturbations induced by scalar perturbations…
