Astronomer on duty: Jeff Mangum

Jeff Mangum is a scientist with the NRAO researching the physics of star formation by analyzing the temperature and density around star forming regions. An expert on radio telescope instrumentation and radio astronomical observing techniques, he uses both of our telescopes — the Very Large Array in New Mexico and ALMA (Atacama Large Millimeter/submillimeter Array) in Chile — to understand how stars form in our Milky Way Galaxy and outside our immediate galactic address. Jeff’s been answering questions for our “Ask an Astronomer” feature since 2000.
