Ask an Astronomer

Astronomer on duty: Jeff Mangum
As a scientist at NRAO, Jeff studies star formation in the Universe at radio through submillimeter wavelengths. He uses molecular spectral line and continuum emission from star formation regions to measure the physical conditions in these regions. With the help of the The Very Large Array and The Atacama Large Millimeter Array (ALMA) radio telescopes, Jeff gathers information on the sub- to mega-parsec scale structure of the spatial density, kinetic temperature, and dynamics of star formation regions. Jeff has been answering questions for Ask an Astronomer since 2000.
