Supermassive boson stars: prospects for observational detection
Diego F. Torres, S. Capozziello, G. Lambiase
In a recent work (Torres, Capozziello and Lambiase, Physical Review D62, 104012 (2000)), it was shown that a supermassive boson star could provide an alternative model for the gala…
Probing the galactic center by gravitational lensing
S. Capozziello, G. Iovane, G. Lambiase +1
The nature of Galactic Center could be probed by lensing experiments capable of testing the spatial and velocity distributions of stars nearby and beyond it. Several hypotheses are…
Newtonian Limit of Induced Gravity
S. Calchi Novati, S. Capozziello, G. Lambiase
We discuss the weak-field limit of induced gravity and show that results directly depend on the coupling and self-interaction potential of the scalar field. A static spherically sy…
Double Scalar-Tensor Gravity Cosmologies
S. Capozziello, G. Lambiase
We investigate homogeneous and isotropic cosmological models in scalar-tensor theories of gravity where two scalar fields are nonminimally coupled to the geometry. Exact solutions…
