How the James Webb, Euclid and Roman space telescopes could team up to hunt supermassive black holes from the dawn of time

New research suggests that three space telescopes could form a powerful triad capable of searching for supermassive black holes earlier in the history of the cosmos than ever detected before.

If the James Webb Space Telescope (JWST), the Euclid telescope, and NASA's upcoming Nancy Grace Roman Space Telescope (Roman) can detect black holes with masses millions or billions of times higher than that of the sun when the universe was less than 270 million years old, it would change our view of cosmic evolution. Such a detection could also solve a dilemma that one of these telescopes revealed to astronomers.
