Nonlinear velocity power spectrum: modeling the cosmological dependence on the Hubble constant and cold dark matter density

Francesca Lepori, Ruth Durrer, Martin Kunz +3

In this paper we present a semi-analytical model for the velocity power spectrum in $\La$CDM cosmology for wave numbers Mpc. We mainly concentrate on the dominant divergence…

Anchors no more: Using peculiar velocities to constrain and the primordial Universe without calibrators

Davide Piras, Francesco Sorrenti, Ruth Durrer +1

We develop a novel approach to constrain the Hubble parameter and the primordial power spectrum amplitude using type Ia supernovae (SNIa) data. By considering…

An Independent Measure of the Kinematic Dipole from SDSS

Prabhakar Tiwari, Dominik J. Schwarz, Gong-Bo Zhao +3

We utilize the Sloan Digital Sky Survey (SDSS) extended Baryon Oscillation Spectroscopic Survey (eBOSS) and Baryon Oscillation Spectroscopic Survey (BOSS) catalogs with precise spe…

A local infall from a cosmographic analysis of Pantheon+

Francesco Sorrenti, Ruth Durrer, Martin Kunz

We present a model independent analysis of the Pantheon+ supernova sample and study the dependence of the recovered values of , and on the redshift cut and on the…

The low multipoles in the Pantheon+SH0ES data

Francesco Sorrenti, Ruth Durrer, Martin Kunz

In previous work we have shown that the dipole in the low redshift supernovae of the Pantheon+SH0ES data does not agree with the one inferred from the velocity of the solar system…

On the detectability of non-trivial topologies

M. Kunz, N. Aghanim, A. Riazuelo +1

We explore the main physical processes which potentially affect the topological signal in the Cosmic Microwave Background (CMB) for a range of toroidal universes. We consider speci…
