Pleased to give a talk (online) to the Cosmology group at Observatório Nacional in Rio de Janeiro. After a short historical intro - discussing the role of pioneers such as Vera Rubin and Gérard de Vaucouleurs - I will present the discoveries of our Cosmicflows research program.

🚨 Advance publication by Camila Franco, Felipe Avila, and Armando Bernui, in #MNRAS on probing isotropy in the Local Universe, using the Arecibo ALFALFA survey data: study finds a signature of the Dipole Repeller we discovered back in 2017. That's just great!

Probing cosmic isotropy in the Local Universe

Abstract. This is a model-independent analysis that investigates the statistical isotropy in the Local Universe using the ALFALFA survey data (0 < z < 0.0

A Brief History of the Discovery of Cosmic Voids

At first the sum total of large, orderly structure in the Universe appeared to arrive in two categories. There were the clusters of galaxies – an unoriginal but descriptive name – each a dense ball with anywhere from a few dozen to a few hundred galaxies, all bound together by their mutual gravitational embrace. And … Continue reading "A Brief History of the Discovery of Cosmic Voids"

“We found a flow pattern reminiscent of streams of water that are organized by gravity to run downhill,” Tully said. “In detail, we played a mathematical trick by inverting the sense of gravity to see where flows would terminate in this altered case. Flows ended at our Dipole Repeller.”
