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…
Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
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…
Fast and spurious: a robust determination of our peculiar velocity with future galaxy surveys
Fabien Lacasa, Camille Bonvin, Charles Dalang +1
To date, the most precise measurement of the observer's peculiar velocity comes from the dipole in the Cosmic Microwave Background (CMB). This velocity also generates a dipole in t…
Towards Cosmography of the Local Universe
Julian Adamek, Chris Clarkson, Ruth Durrer +3
Anisotropies in the distance-redshift relation of cosmological sources are expected due to large-scale inhomogeneities in the local Universe. When the observed sources are tracing…
