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…
Reconstructing the kinematics of Laniakea using Type Ia Supernovae
Francesco Sorrenti, Erick Pastén, Leonardo Giani
We develop a kinematic framework that relates the monopole, dipole, and quadrupole of the luminosity distance to an ellipsoidal peculiar velocity field describing the dynamics of t…
Exploring the cosmic microwave background dipole direction using gamma-ray bursts
Orlando Luongo, Marco Muccino, Francesco Sorrenti
We search for dipole variations in the Hubble constant using gamma-ray burst (GRB) data, as such anisotropies may shed light on the Hubble tension. We employ the most recent…
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…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
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…
