Keduse Worku is an undergraduate Astrophysics major at Yale University graduating this upcoming Fall semester. This summer, he is working with Professor Jo Dunkley to probe dark energy using anisotropies in the CMB. Because the Integrated Sachs-Wolfe (ISW) and Sunyaev–Zel’dovich (SZ) effects derive from the same physical process near galaxy clusters, the project seeks to find the ISW-SZ cross spectrum to fit dark energy cosmological parameters.
His academic year research is in exoplanets with Professors Gregory Laughlin and Songhu Wang. Through MCMC-based analysis of photometry and radial velocity data, he determines planetary parameters for a highly eccentric hot Jupiter system. During a previous summer at the CfA with Dr. Grant Tremblay, Keduse has also examined the kinematics of Milky-Way massed galaxies through probing ionized and molecular gases as well as black hole outflows.”
