Saturday Physics for Everyone: "The First Galaxies in the Universe and the ALMA Telescope", September 12, 2015 Professor Joaquin Vieira is an observational cosmologist interested in the cosmic microwave background, experimental tests of inflation, dark matter, dark energy, gravitational lensing, high redshift galaxies, and instrumentation. He builds experiments, conducts cosmological surveys, and performs observations of the distant Universe. He works with data from the South Pole Telescope, Herschel, Hubble, Spitzer, Chandra, and the Atacama Large Millimeter Array (ALMA).  In this talk, he will tell us about the first galaxies and about ALMA, the largest astronomical project in existence. ALMA is a single telescope of revolutionary design, composed of 66 high precision antennas located on the Chajnantor plateau in northern Chile, at 5000 meters altitude.
