Breaking the mass-sheet degeneracy with gravitational wave interference in lensed events
Paolo Cremonese, Jose María Ezquiaga, Vincenzo Salzano
The mass-sheet degeneracy is a well-known problem in gravitational lensing which limits our capability to infer astrophysical lens properties or cosmological parameters from observ…

High accuracy on constraints from gravitational wave lensing events
Paolo Cremonese, Vincenzo Salzano
In light of the newly opened and rapidly growing gravitational waves window in multi-messenger astronomy, in order to fully take advantage of the new opportunities we are provided…

The lensing time delay between gravitational and electromagnetic waves
Paolo Cremonese, Edvard Mörtsell
The recent detection of gravitational waves (GWs) and electromagnetic (EM) waves originating from the same source marks the start of a new multi-messenger era in astronomy. The arr…
