Light rings of five-dimensional geometries
Massimo Bianchi, Dario Consoli, Alfredo Grillo +1
We study massless geodesics near the photon-spheres of a large family of solutions of Einstein-Maxwell theory in five dimensions, including BHs, naked singularities and smooth hori…
The multipolar structure of fuzzballs
Massimo Bianchi, Dario Consoli, Alfredo Grillo +3
We extend and refine a general method to extract the multipole moments of arbitrary stationary spacetimes and apply it to the study of a large family of regular horizonless solutio…
Distinguishing fuzzballs from black holes through their multipolar structure
Massimo Bianchi, Dario Consoli, Alfredo Grillo +3
Within General Relativity, the unique stationary solution of an isolated black hole is the Kerr spacetime, which has a peculiar multipolar structure depending only on its mass and…
On the N-pion extension of the Lovelace-Shapiro model
Massimo Bianchi, Dario Consoli, Paolo Di Vecchia
We reconsider a modification of the N-point amplitude of the Neveu-Schwarz (NS) model in which the tachyon becomes a pion by shifting its mass to zero and keeping the super-project…
The dark side of fuzzball geometries
Massimo Bianchi, Dario Consoli, Alfredo Grillo +1
Black holes absorb any particle impinging with an impact parameter below a critical value. We show that 2- and 3-charge fuzzball geometries exhibit a similar trapping behaviour for…
