Detectability of Gravitational-Wave Memory with LISA: A Bayesian Approach
Adrien Cogez, Silvia Gasparotto, Jann Zosso +5
Gravitational wave (GW) astronomy opens a new venue to explore the universe. Future observatories such as LISA, the Laser Interferometer Space Antenna, are expected to observe prev…
Scalar memory from compact binary coalescences
Jann Zosso, Silvia Gasparotto, Llibert Aresté Saló +2
Gravitational memory provides a distinctive low-frequency probe of gravity, but explicit merger studies beyond general relativity remain limited. In this letter, we investigate mem…
Toward claiming a detection of gravitational memory
Jann Zosso, Lorena Magaña Zertuche, Silvia Gasparotto +3
Gravitational memory is a zero-frequency effect associated with a permanent change in the asymptotic spacetime metric induced by radiation. Although its universal manifestation is…
Gravitational Memory from Hairy Binary Black Hole Mergers
Silvia Gasparotto, Jann Zosso, Llibert Aresté Saló +2
Gravitational-wave memory is a low-frequency, non-oscillatory component of the radiation field that provides a potentially powerful but as yet undetected probe of strong-field grav…
Testing gravitational wave polarizations with LISA
Shingo Akama, Maxence Corman, Paola C. M. Delgado +16
In this paper we quantify the ability of the Laser Interferometer Space Antenna (LISA) to test the presence of non-tensorial polarizations as well as modifications to the tensor on…
Balance flux laws beyond general relativity
David Maibach, Jann Zosso
Balance flux laws of asymptotic symmetries in general relativity provide fully non-perturbative constraint equations on gravitational strain. They have proven useful for constructi…
