Unveiling the largest structures in the nearby Universe - discovery of the Quipu superstructure: https://arxiv.org/abs/2501.19236 -> Largest #superstructure in the nearby #universe discovered: https://www.mpg.de/24197951/largest-superstructure-in-the-nearby-universe - data from the former #ROSAT X-ray satellite have revealed a network of 68 galaxy clusters in the nearby universe, stretching over 1.4 billion light-years.
arXiv.orgUnveiling the largest structures in the nearby Universe: Discovery of the Quipu superstructureFor a precise determination of cosmological parameters we need to understand the effects of the local large-scale structure of the Universe on the measurements. They include modifications of the cosmic microwave background, distortions of sky images by large-scale gravitational lensing, and the influence of large-scale streaming motions on measurements of the Hubble constant. The streaming motions, for example, originate from mass concentrations with distances up to 250 Mpc. In this paper we provide the first all-sky assessment of the largest structures at distances between 130 and 250 Mpc and discuss their observational consequences, using X-ray galaxy clusters to map the matter density distribution. Among the five most prominent superstructures found, the largest has a length longer than 400 Mpc with an estimated mass of about 2 10e17 Msun. This entity, which we named Quipu, is the largest cosmic structure discovered to date. These superstructures contain about 45% of the galaxy clusters, 30% of the galaxies, 25% of the matter, and occupy a volume fraction of 13%, thus constituting a major part of the Universe. The galaxy density is enhanced in the environment of superstructures out to larger distances from the nearest member clusters compared to the outskirts of clusters in the field. We find superstructures with similar properties in simulations based on Lambda-CDM cosmology models. We show that the superstructures should produce a modification on the cosmic microwave background through the integrated Sachs-Wolf effect. Searching for this effect in the Planck data we found a signal of the expected strength, however, with low significance. Characterising these superstructures is also important for astrophysical research, for example the study of the environmental dependence of galaxy evolution as well as for precision tests of cosmological models.

Some scientific discoveries shake up my brain.
On the one hand, it almost blows my mind when I think about it further. On the other hand, it's wonderfully reassuring to realise that there are a lot more important and fascinating things in this cosmos than some evil guys on two small legs.

Meet Quipu, largest known structure in the universe
A team of astronomers have mapped the nearby universe, from about 425 million to 800 million light-years (which translates to some 130 to 250 megaparsecs), and discovered the largest-known structure residing there. They’ve named this massive collection of galaxies Quipu. And they said it stretches some 1.3 billion light-years (400+ megaparsecs) long, containing the mass of some 200 quadrillion stars.
Uh, give or a take a few billion stars...

Using the sun as a baseline, astronomers can measure when a #star formed by determining its #metallicity, or the level of heavy elements present within it.
Metal-rich #stars or nebulas formed relatively recently, while metal-poor objects were likely present during the early #universe.
The formation of super-Earths, #planets more massive than the Earth, near metal-poor stars is significantly more difficult than near high-metalliciry ones.

@everyone.
Live Science · 800-mile-long 'DUNE' experiment could reveal the hidden dimensions of the universe
Is the #universe flat and infinite, or something more complex?
We can’t say for sure, but a new search strategy is mapping out the subtle signals that could reveal if the universe had a shape.

Space · How 'quantum foam' may have inflated the early universe
Cosmologists strongly suspect that the extremely early #universe underwent a period of exceptionally rapid expansion known as #inflation
This event expanded the universe by ar least 60 orders of magnitude in less than a second.
But inflation also laid down the seeds of the first structures by generating gravitational waves sloshing around in the infant universe.
