An ultra-high-resolution map of (dark) matter

Diana Scognamiglio, Gavin Leroy, David Harvey +38

Ordinary matter-including particles such as protons and neutrons-accounts for only about one sixth of all matter in the Universe. The rest is dark matter, which does not emit or ab…

Cosmic Vine: High abundance of massive galaxies and dark matter halos in a forming cluster at z=3.44

Nikolaj B. Sillassen, Shuowen Jin, Georgios E. Magdis +10

The Cosmic Vine is a massive protocluster at z=3.44 in the JWST CEERS field, offering an ideal laboratory for studying the early phases of cluster formation. Using the data from th…
