The #CosmicWeb is made up of large #voids delimited by long filaments of #matter at the intersection of which vast #gravitational structures are formed: #galaxies grouped into clusters.

Do their properties (mass, shape, star formation rate) preserve traces of the large-scale cosmic flows from which they originated? Find out this Thursday with Katarina Kraljic, a researcher at the @ObsStrasbourg , who studied a sample of observed and virtual galaxies : https://www.irap.omp.eu/event/the-co-evolution-of-galaxies-and-the-cosmic-web-over-cosmic-time/

[Zoom on the #CosmicWeb] Have you dived into the deep fields of #Euclid revealed this Wednesday by the @ec_euclid ? Have you navigated between the thousands of #galaxies of different shapes, sizes, colors and masses? So many objects, near and far, fill our #Universe! https://sky.esa.int/esasky/?hide_welcome=true&hide_banner_info=true&hips=DES-DR2+ColorIRG&sci=false&layout=esasky&euclid_image=EDFS

What if their spatial distribution could tell us something about two mysterious components : #DarkMatter and #DarkEnergy? This is the gamble taken by the scientists involved in the Euclid mission. To do so, they've designed some unrivalled #instruments: a camera with great depth of field and high resolution records the variety of shapes and spatial distribution of galaxies, while a #spectrometer coupled with a #photometer can determine the distances and masses of galaxies ...

Get ready to feel cosmically insignificant.

Cosmologists Parry Attacks on the Vaunted Cosmological Principle
A central pillar of cosmology — the universe is the same everywhere and in all directions — is surviving a storm of possible evidence against it.
