Reconstructing the largest scales of the Universe with field-level inference applied to the Quaia Quasar Catalogue The recently released Quaia quasar catalogue, with its broad redshift range and all-sky coverage, enables unprecedented three-dimensional reconstructions of matter across cosmic time. In this work, we...

It's cool #PaperDay today @oskarkleincentre.bsky.social, #Astronomy #Cosmology!

We used a physics informed Field Level Inference method applied to a large Quasar sample to reconstruct the inicial conditions, matter field and dynamics of the Universe at the largest scales!

We have a new paper on @nature.com and how we solve a 50 year-old riddle about Andromeda's peculiar motion. www.insu.cnrs.fr/fr/cnrsinfo/... www.nature.com/articles/s41...

Structures cosmiques : une famille de géantes Comment Quipu, structure parmi les plus grandes, a-t-elle été identifiée ? De quoi sont composées filaments de galaxies et de matière noire, forment les structures de l'univers ? En quoi leur identifi...

[RDV 16h !] Aujourd'hui on explore la toile cosmique 🕸️🛰️
Comment les grandes structures de l'univers se sont-elles construites ? Quipu, la dernière découverte annoncée, est-elle la plus grande jamais observée ?🌌
Avec Daniel Pomarède et Guilhem Lavaux #ScienceCQFD

La #ScienceCQFD c'est fini pour aujourd'hui mais on se retrouve lundi pour parler des grandes structures de l'univers ! 🌌
Ce sera, comme toujours, à 16h sur @franceculture.fr ! #ScienceCQFD

Enhancing Thermal Sunyaev-Zel'dovich Analyses with Digital Twins of the Local Universe The thermal Sunyaev-Zel'dovich (tSZ) effect provides a powerful probe of the thermal pressure of ionised gas in galaxy clusters and the cosmic web; constrained simulations reconstruct the mass and vel...

Field-level large-scale structure meets the CMB BORG is designed for local large-scale structure, but it has significant potential for CMB studies as well. We develop a framework for connecting constrained simulations to the thermal Sunyaez-Zel'dov...

Paper day ! We got a new work by Harry Desmond and Richard Stikalek on Manticore vs tSZ effects from galaxy clusters.

A 1.8% measurement of the Hubble constant from Cepheids alone The strongest tension within the concordance model of cosmology is a mismatch between the Universe's expansion rate inferred from the cosmic microwave background vs the local distance ladder. We const...

Richard Stiskalek and Harry Desmond published new results on how to measure the Hubble constant from Cepheids alone, and the impact on the current debate on the tension with high redshift measurements. Please see the summary post here:
