Giles Novak Professor PhD, University of Chicago, 1988 NSF Faculty Early Career Development Award Giles Novak's research is in the area of observational astrophysics and astrophysical instrumentation.  His research group developed a polarimetric imager for use at the South Pole.  This instrument, called SPARO (Submillimeter Polarimeter for Antarctic Remote Observations), has been used to map large-scale Galactic magnetic fields.  The goal is to study the role that these fields play in the process of star formation, and in the dynamics of the Galactic center region. Novak is also leading a team that is developing a new submillimeter polarimeter for the ten-meter Caltech Submillimeter Observatory, located at the summit of Mauna Kea, Hawaii.  This new instrument is called SHARP.  The primary science goals are to map magnetic fields in the vicinity of low-mass protostars and to study the structure of magnetohydrodynamic turbulence in star-forming clouds.  Another application of SHARP is the study of black hole accretion in the Sagittarius A* source.
