  4. James Webb Telescope captures the first direct image of a 3-million-light-year cosmic web filament connecting galaxies from 12 billion years ago

    Astronomers have produced the sharpest image to date of a 3-million-light-year filament connecting galaxies from nearly 12 billion years ago.

  5. Astronomers using NASA’s James Webb Space Telescope (JWST) have created the most detailed map ever produced of the cosmic web, the enormous structure that connects galaxies across the universe

  7. A DESI Milestone

    Yesterday the Open Journal of Astrophysics published a paper by Porredon et al which will feature in the usual Saturday round-up. That paper, which is based on the First Data Release from the Dark Energy Spectroscopic Instrument (DESI) reminded me that I should mention that DESI recently reached an amazing milestone – it has now mapped the positions and redshifts of 47 million galaxies and quasars! There is a full press-release about this achievement here.

    Here’s a little video showing how the survey works:

    https://www.youtube.com/watch?v=6H3diAK_KIc

    There are more videos and other graphics in the press release.

    Here’s a nice picture showing a thin slice through the full survey that reveals the characteristic “cosmic web” of the large-scale structure of the Universe in all its glory:

    This progress is great, but it really makes me feel old. Forty years ago, in 1986, I had just started my PhD. The state-of-the-art galaxy redshift survey slice then is shown in this plot, from de Lapparent et al 1986 (ApJLett 302, L1), one of the first papers I read as a research student (I got it in 1985 as a preprint), which contains just 1,100 galaxies:

    It is worth mentioning that although DESI has now covered its original target area, it will continue until 2028. You can never have too many galaxy redshifts!

  13. 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 : irap.omp.eu/event/the-co-evolu

  25. Astronomers used background X-rays to study the “cosmic web” of gas between galaxies and discovered that cosmic filaments are spinning, challenging our understanding of the universe’s evolution. This breakthrough by MPE_Garching researchers explains how galaxies acquire angular momentum. Science continues to reveal our amazing universe!

  27. [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! sky.esa.int/esasky/?hide_welco

    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 ...
