The DESI Peculiar Velocity Survey, the largest survey of galaxies peculiar velocities planned to date. Great stuff for the future of mapping the universe with cosmic flows!

Un magnifique manuscrit du XVe siècle, sans doute produit en Italie, qui comprend un recueil des cartes de la Cosmographie de Ptolémée, introduite par un beau portrait...

There's a huge void at the edge of the Milky Way and it's getting bigger and emptier.

Check out this paper by Aristos Georgiou writing for Newsweek on how astronomers have cast new light on a huge, empty void that encircles our galaxy, the Milky Way: newsweek.com/huge-void-edge-mi

The study published in the Astrophysical Journal: doi.org/10.3847/1538-4357/ab25

One of my map of the universe makes it to the cover of The Astronomical Journal. It shows the evacuation of cosmic flows out of the Local Void, a giant cosmic void found in our immediate vicinity. Our galaxy the Milky Way is at the center and the map also features the Virgo galaxy cluster, located 50 million light-years away.

The Expanses

Check out our paper on the vast expanses discovered and charted by our Cosmicflows research program, published recently in the Cosmo of ’69 Cosmology Blog. Many thanks to Jenny Wagner and her team for their invitation to write in this new venue.

A video map of the Local Void, a large underdense region of the Universe, on the outskirts of which is located our galaxy the Milky Way, and of its relation with other cosmic voids and major overdense neighbors.

A great filament runs from the Great Attractor through Norma–Pavo–Indus, across the Arch that forms a far boundary of the Local Void, to the Perseus–Pisces structure. Midway along the Arch, there is a point of bifurcation between local flows that either head to Perseus–Pisces or toward the Great Attractor.

This is Fig.6 of doi.org/10.3847/1538-4357/aa7f
