Unveiling the Turbulent 'Teenage Years' of the Universe

Combining data from different telescopes is one of the best ways to get a fuller picture of far-off objects. Because telescopes such as Hubble (visible light), the James Webb Space Telescope (infrared), and the Atacama Large Millimeter Array (radio) each collect data in different wavelengths, they are able to capture distinct features of objects like galaxies that other telescopes cannot observe. A new paper by a large group of authors, headed by Andreas Faisst of Caltech, presented at the American Astronomical Society Meeting last week and published in The Astrophysical Journal Supplement tracks eighteen early galaxies in as broad of a spectrum as those instruments can collect, and most significantly found that they seem to “grow up” faster than expected.
