Abstract
In this educational seminar, we consider the intriguing relationship between two seemingly unrelated concepts: vector spherical harmonics and the proper orthochronous Lorentz group.
On the one hand, vector spherical harmonics are a powerful tool widely used in the study of optical systems. On the other hand, the proper orthochronous Lorentz group is a subgroup of the Lorentz group, consisting of rotations and boosts.
Our exploration will reveal a connection between vector spherical dipoles, which are specific types of vector spherical harmonics, and the movements of stars on the celestial sphere under Lorentz transformations.
