Cherenkov Bursts are Memory Steps
Jann Zosso, Guangzi Xu, Vitor Cardoso
We show that the familiar Cherenkov burst from a finite superluminal charge track can be understood as a pair of interfering electromagnetic memory transitions. Endpoint accelerati…
Low-Frequency Gravitational Bremsstrahlung and Memory in a Medium
Diego Blas, Silvia Gasparotto, Hitoshi Murayama +2
Gravitational radiation from the early Universe offers a powerful window into physics beyond the Standard Model (SM). In this paper, we investigate the low-frequency tail of gravit…
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…
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…
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…
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 in Generalized Proca Gravity
Lavinia Heisenberg, Benedetta Rosatello, Guangzi Xu +1
We investigate the gravitational memory effect in the full Generalized Proca gravity, the most general metric theory including a gravitational Proca field with derivative self-inte…

Jann Zosso
We show that the amplitude of electromagnetic memory can be significantly enhanced in comparison to known estimates. In a Lorentz breaking phase of lowered phase velocity of light,…
Continuing Isaacson's Legacy: A general metric theory perspective on gravitational memory and the non-linearity of gravity
Jann Zosso
The challenge of defining a physical notion of gravitational waves, together with the associated dynamical degrees of freedom of a gravity theory, is a long-standing problem that f…
Constraining superluminal Einstein-Æther gravity through gravitational memory
Lavinia Heisenberg, Benedetta Rosatello, Guangzi Xu +1
Every emission of radiation in gravity also includes a nonwavelike component that leaves a permanent change in proper distances of the spacetime it travels through. This phenomenon…
Probing Gravity -- Fundamental Aspects of Metric Theories and their Implications for Tests of General Relativity
Jann Zosso
Guided by the Einstein equivalence principle that identifies the phenomenon of gravitation as a manifestation of the dynamics of spacetime in contrast to a localizable force, we re…
