Effective delta sources and Newtonian limit in nonlocal gravity
Thomas M. Sangy, Nicolò Burzillà, Breno L. Giacchini +1
We investigate the Newtonian limit of a class of nonlocal gravity models with exponential form factors . Our main goal is to identify simil…
Spherically symmetric solutions in quasi-local Einstein-Weyl gravity
Johanna Borissova, Breno L. Giacchini, Aaron Held
Quantum-gravitational effective actions with higher-derivative and non-local operators are expected to regularize the singularities of general relativity. Here we focus on quasi-lo…
Neglected solutions in quadratic gravity
Breno L. Giacchini, Ivan Kolář
We report on several previously overlooked families of static spherically symmetric solutions in quadratic gravity. Our main result concerns the existence of solutions whose leadin…
Black holes and other exact solutions in six-derivative gravity
Breno L. Giacchini, Ivan Kolář
We study exact static spherically symmetric vacuum solutions in generic six-derivative gravity (i.e., without assuming specific relations between the coupling constants). Using mod…
