Title“What we can learn from cross-correlations between UHECRs and galaxies”
AbstractAngular, harmonic cross-correlations between different cosmological fields are a well-known tool that has recently catalysed several detections, e.g. between gamma-ray sources and weak lensing. I will review the motivations and theoretical foundations of the application of cross-correlation to UHECRs and galaxies, highlighting its benefits and shortcomings. I will then give a simple example of a possible application in the study of UHECR composition at the highest energies.
