Electromagnetic decays of mesons play an important role in understanding the structure of hadronic states, testing the Standard Model (SM) predictions, and probing for New Physics beyond the SM. In this talk, I present recent results from our research group on this topic, including the radiative and Dalitz decays of bottom and charm mesons. The hadronic form factors required for these studies are calculated using the Covariant Confined Quark Model developed by our group. A brief discussion of the ATOMKI X(17) anomaly is also provided.
