Higher spin fields have a great variety of impacts on our universe. For example, magnetic fields (spin 1) are deeply associated with structure formations of varied sizes, and gravitational waves (spin 2) generate distinctive signatures in CMB. A main goal of my research is to understand the origins of these cosmic spin dependencies, through phenomenological studies and parameter estimations based on observational data. My recent/ongoing activities are to find new observables for symmetry breakings (non-Gaussianity, broken rotational invariance, parity violation) motivated by higher spin fields, to build these estimators, and to constrain these observables from new CMB temperature and polarization data in the ESA Planck collaboration.
