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.

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.

The James Webb Space Telescope (JWST) was designed to be "a giant leap forward in our quest to understand the Universe and our origins." Faithful to its core mission, JWST shows us an unprecedented—and somewhat unexpected—view of the high-z Universe, particularly concerning early galaxy and black hole formation. Before the advent of JWST observations, the "black hole horizon," defined as the farthest redshift where a black hole can be detected, stood at z ∼ 7–8.
