Searching for Planets with SDSS/MARVELS

Dr. Duy Cuong Nguyen, Dunlap Institute

The primary mission of SDSS/MARVELS was to search for exoplanets using an augmented radial velocity technique. While there are numerous ongoing radial velocity surveys, SDSS/MARVELS employs Dispersed Fixed-Delay Interferometry (DFDI), and combines interferometry with multi-object spectroscopy to allow precision monitoring of dozens of targets simultaneously. Along with multi-object capability, the setup also allows for radial velocity sensitivity equivalent to high-resolution echelle spectrographs while maintaining a much tighter wavelength dispersion, which allows significantly fainter targets to be observed.

Dr. Duy Cuong Nguyen is a member of the Dunlap Institute through the Apache Point Observatory Galactic Evolution Experiment (APOGEE) project. APOGEE is a high-resolution infrared spectroscopic survey of 100,000 stars across the Milky Way, and is one of the Sloan Digital Sky Survey (SDSS) III and IV projects. He focuses on the search for and characterization of exoplanets and their hosts, the origin and diversity of planetary systems, and the formation of stars and brown dwarfs. Dr. Nguyen received his PhD from the University of Toronto, and has held positions at the University of Florida, Stockholm University, and the University of Rochester. He joined the Dunlap Institute in July 2013.
