Yulia Gurevich (Postdoctoral Associate w/Steve Lamoreaux) has been awarded a Marie Curie Fellowship to work with Prof. Andreas Quirrenbach at the University of Heidelberg.
The project is to develop a calibrator for astronomical spectrographs based on a Fabry-Perot etalon that is actively stabilized to an atomic transition. She was involved in building a proof-of-principle demonstration of this idea in collaboration with the University of Heidelberg and Penn State University. She presented this work at the 2014 SPIE Astronomical Instrumentation conference, and we have an article in the proceedings. Her work in Heidelberg will entail developing this prototype into a robust calibration unit suitable for use at an observatory and testing its performance on-sky using the CARMENES spectrograph.
