The Large Scale Structure and us

a map of the galaxy density field spanning over 700 million light years. Note how insignificant is our Local Group, that is, our home group of galaxies, in the grand scheme of things!

this is figure 8 of http://doi.org/10.1088/0004-6256/146/3/69

Discovery alert!

A spherical shell-like structure 1 billion light-years in diameter named Ho’oleilana is discovered in the distribution of relatively nearby galaxies. We posit this is the 1st observation of an individual Baryon Acoustic Oscillation (BAO).

An artist's view of Ho'oleilana. The three-dimensional shell enclosed by the Baryon Acoustic Oscillation is colorized in reddish/orange/brown color and enhanced to capture its content in terms of galaxies and to expose how it is encapsulated in the larger structure of the Cosmic Web. Galaxies are shown as luminous tiny specks. The Cosmic Web is represented as the blueish filamentary maze. This view also exposes the other structures discovered by the Cosmicflows research program: Laniakea our Home supercluster of galaxies; the South Pole Wall, a giant filament of the cosmic web that embraces the sourthernmost frontiers of Laniakea; the Dipole Repeller and the Cold Spot Repeller, two underdense regions presumably associated to two giant cosmic voids.

The first three issues of Worlds of IF science fiction since the revival by Starship Sloane Publishing. They look good in print!

Each issue has a story by me: "Our Place on the Map of the Universe", "From Deep Darkness came Murmurs of Awakening", and "A Three-Dimensional Chessboard Universe"

Prints and digital copies available at https://worldsofifmagazine.com/
