New Views of Galaxy Formation and Evolution

[Image credit: Nicolle R. Fuller, NSF] Sensitive ground- and space-based astronomical facilities are pushing the detection of galaxies well into the Epoch of Reionization, less than 1 Gyr after the Big Bang. Such detections are allowing us to begin piecing together a picture for how and when the first galaxies formed, along with the physical ...
