Another clue about the whereabouts of the missing matter in the Universe has just emerged from amid the largest local cosmic structure. X-ray observations have revealed a massive filament of hot gas in the enormous, 8,000-galaxy strong Shapley Supercluster. www.aanda.org/articles/aa/...

The excellent press release by ESA regarding our latest work and the first unambiguous detection of the missing baryons and warm-hot intergalactic medium in a single filament!

📢Paper and press releases day! We report the first-ever unambiguous detection of WHIM/missing baryons in a single cosmic filament using @ESA_XMM and @JAXA_en Suzaku data! It's the first time observations agree with LCDM simulations for the nature of WHIM www.aanda.org/articles/aa/...

Delighted to share that I got yet another research grant from @unileiden.bsky.social and the Fonds Rijke-Hamaker fund! 🥳 This grant will support my analysis of new X-ray data of galaxy clusters that will eventually help us further refine our understanding of the uniformity of cosmic expansion!

(My first post) I'm thrilled to receive an NWO Open Competition grant to test the uniformity of cosmic expansion at local and distant cosmic scales, using eROSITA and @esa.int XMM-Newton data of X-ray galaxy clusters! This means I get to stay longer at Leiden Observatory 🥳 tinyurl.com/NWOgrant
