AbstractThe James Webb Space Telescope (JWST) has spectroscopically confirmed numerous galaxies at z > 10. While weak rest-frame ultraviolet emission lines have only been seen in a handful of sources, the stronger rest-frame optical emission lines are highly diagnostic and accessible at mid-infrared wavelengths with the Mid-Infrared Instrument (MIRI) of JWST.

AbstractRecent observations have found a large number of supermassive black holes already in place in the first few hundred million years after the Big Bang, many of which seem to be overmassive relative to their host galaxy stellar mass when compared with local relation1,2,3,4,5,6,7,8,9. Several different models have been proposed to explain these findings, ranging from heavy seeds to light seeds experiencing bursts of high accretion rate10,11,12,13,14,15,16.

AbstractThe first observations of JWST have revolutionized our understanding of the Universe by identifying for the first time galaxies at \(z\sim 13\)1–3. In addition, the discovery of many luminous galaxies at Cosmic Dawn (\(z > 10\)) has suggested that galaxies developed rapidly, in apparent tension with many standard models4–8. However, most of these galaxies lack spectroscopic confirmation, so their distances and properties are uncertain.

AbstractMultiple theories have been proposed to describe the formation of black hole seeds in the early Universe and to explain the emergence of very massive black holes observed in the first billion years after Big Bang1–3. Models consider different seeding and accretion scenarios4–7, which require the detection and characterisation of black holes in the first few hundred million years after Big Bang to be validated.
