On tilted Giraud subcategories

Firstly we provide a technique to move torsion pairs in abelian categories via adjoint functors and in particular through Giraud subcategories. We apply this point in order to develop a correspondence between Giraud subcategories of an abelian category $C$ and those of its tilt $H(C)$ i.e., the heart of a t-structure on $D(C)$ induced by a torsion pair.
