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…

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…

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…

Enhancement of Electromagnetic Memory Effects

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…
