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…
