 This study presents a comprehensive analysis of dipolar bright solitons in dipolar Bose-Einstein condensates, revealing the rich behavior introduced by non-local non-linearity through mapping out their existence and showing three-collisional regimes, free collisions, bound state formation, and soliton fusion. The study also examines the soliton's full three-dimensional form through a variational approach, identifying regimes of stability accessible to current experiments, while also highlighting instabilities to collapse and runaway expansion.
