U-M Department of Physics undergraduate physics majors Dan Mantica, Conrad Holtsclaw, and Grant Renny have spent their summer abroad conducting research in three different physics projects at the University of Science and Technology of China (USTC) in Hefei, China.

Dan Mantica’s research project is on gravitational wave sources. Gravitational waves are waves with two independent polarizations that travel at the speed of light through the curvature of space-time and are predicted by Einstein's Theory of General Relativity. Dan is studying the theoretical strengths and types of signals that are produced by different gravitational wave sources, which include binary neutron star and black hole systems and supernovae.

Conrad Holtsclaw is performing data analysis with the Beijing Electron Spectrometer Three (BESIII). The BESIII detector is used for a great range of experiments, but the goal of the lab there is to gain insight into the inner structure of the proton. Conrad’s work has been to create a program which filters proton-antiproton events from a host of other events and background radiation.

Grant Renny’s lab group is working on the Dark Matter Particle Explorer (DAMPE) satellite that will be launched in 2015. It is a high-energy, 5GeV-10TeV electron/gamma ray detector. Grant has been working on the construction and calibration of the plastic scintillator for the satellite. His group is currently testing the efficiency and position accuracy of the scintillator.

The students have traveled to the Hui villages of Hongcun and Xidi along with trips to Shanghai and Beijing and the Institute of High Energy Physics (IHEP). They will return to Ann Arbor for classes at U-M this fall.
