A morphological study of two rich superclusters: the Sloan Great Wall and the Sculptor Supercluster.

The three dimensional distribution of galaxies in the nearest, almost complete part of the 2dFGRS (up to 400 h–1 Mpc). The two richest superclusters in this survey are shown. The disk showing the orientation of the Galactic plane helps to allocate the 2dF survey in space; SCl 126 (Sloan Great Wall) is located toward the north Galactic pole (left, red color), and SCl 9 (Sculptor Supercluster) is at the right side of the figure (blue color).

New post & paper by S. McAlpine et al: Manticore-Deep: Bayesian Digital Twins of Cosmic Structure Across SDSS and BOSS Volumes.
This is the first high-resolution Bayesian reconstruction of cosmic structure across a (4 h⁻¹Gpc)³ volume out to z≈0.7.

Manticore-Deep: Bayesian Digital Twins of Cosmic Structure Across SDSS and BOSS Volumes
Manticore-Deep is the first high-resolution Bayesian reconstruction of cosmic structure across a (4 h⁻¹Gpc)³ volume out to z≈0.7, jointly constraining 2M++, 6dFGS, 2dFGRS, SDSS, and BOSS.

Un'esplosione cosmica con la forza di un miliardo di soli è passata inosservata, finché non ne abbiamo colto l'eco

Alcune delle esplosioni più estreme dell’universo non lasciano quasi alcuna traccia visibile. L’esplosione iniziale non viene […]

L’immagine a sinistra mostra la posizione del radio–afterglow all’interno della galassia 2dFGRS TGS143Z140, ripresa con il Magellan Telescope in Cile. A destra vediamo la stessa sorgente radio rilevata dal Giant Metrewave Radio Telescope in India.

Cosmic Latte: The Average Color of the Universe

A solid beige square representing the average color of the universe, also known as Cosmic Latte, as determined by averaging the light of 200,000 galaxies from the 2dF Galaxy Redshift Survey. The color has shifted from blue to beige over billions of years due to the increasing prevalence of redder stars.
