Gravitational wave lensing: probing Fuzzy Dark Matter with LISA
Shashwat Singh, Guilherme Brando, Stefano Savastano +1
Gravitational lensing is a universal phenomenon: it affects both gravitational waves (GWs) and electromagnetic signals travelling through the gravitational field of a massive objec…
GLoW: novel methods for wave-optics phenomena in gravitational lensing
Hector Villarrubia-Rojo, Stefano Savastano, Miguel Zumalacárregui +4
Wave-optics phenomena in gravitational lensing occur when the signal's wavelength is commensurate to the gravitational radius of the lens. Although potentially detectable in lensed…
Weakly Lensed Gravitational Waves: Probing Cosmic Structures with Wave-Optics Features
Stefano Savastano, Giovanni Tambalo, Hector Villarrubia-Rojo +1
Every signal propagating through the universe is at least weakly lensed by the intervening gravitational field. In some situations, wave-optics phenomena (diffraction, interference…
Through the lens of Sgr A: identifying and resolving strongly lensed Continuous Gravitational Waves beyond the Einstein radius
Stefano Savastano, Filippo Vernizzi, Miguel Zumalacárregui
Lensed gravitational waves will offer new means to probe the distribution of matter in the universe, complementary to electromagnetic signals. Lensed continuous gravitational waves…
Constraining the evolution of Newton's constant with slow inspirals observed from spaceborne gravitational-wave detectors
R. Barbieri, S. Savastano, L. Speri +5
Spaceborne gravitational-wave (GW) detectors observing at milli-Hz and deci-Hz frequencies are expected to detect large numbers of quasi-monochromatic signals. The first and second…
Primordial dark matter halos from fifth forces
Stefano Savastano, Luca Amendola, Javier Rubio +1
We argue that primordial dark matter halos could be generated during radiation domination by long range attractive forces stronger than gravity. In this paper we derive the conditi…
