In this Shadow the Scientists session, the observing team will be using the Keck I 10-meter telescope on the summit of Maunakea on the Big Island of Hawai`i to look at a part of the sky called the Extended Chandra Deep Field South, made famous by being the subject of one of the deepest images ever recorded by the Hubble Space Telescope. This part of the sky has also been observed with NASA’s fleet of great space observatories as well as those from the European Space Agency. However, despite over two decades of observations in this part of the sky, some discoveries have been elusive. During this StS session, the research team will observe galaxies using a technique called near-infrared multi-object spectroscopy with an instrument called MOSFIRE to target a large group of galaxies under formation when the universe was about 15% of its current age. This group of galaxies is suspected to house galaxies ripe with activity, from violent starbursts to energetic black holes. With these observations, they will be measuring the distances to galaxies, estimating the numbers of stars they form, the activity of their black holes, and how galaxies are transformed as they assemble into massive structures in the early Universe.
