482“…Thus, the tantalizing prospect to test the fundamental nature of gravity with gravitational-wave observations, in a systematic way, emerges naturally. Here, we build black hole solutions in such a framework and study their main properties. …”

490por Torrente-Lujan, E.“…Mass formulas for multicenter BPS 4D black holes are presented. In the case of two center BPS solutions, the ADM mass can be related to the intercenter distance r , the angular momentum J2 , the dyonic charge vectors qi and the value of the scalar moduli at infinity ( z∞ )by the Smarr-like expression MADM2=A(1+αJ2(1+2MADM/r+A/r2)) where A(Q),α(qi) are symplectic invariant quantities ( Q , the total charge vector) depending on the special geometry prepotential defining the theory. …”

497por Romano, Antonio Enea“…We study different mechanisms by which the speed of primordial curvature perturbations can produce an enhancement of the curvature spectrum, which could lead to the production of primordial black holes (PBH). One possibility is the growth of the sound speed in single scalar field models, which can induce super-horizon growth of curvature perturbations. …”
