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…

Unifying Ordinary and Null Memory
Lavinia Heisenberg, Guangzi Xu, Jann Zosso
Based on a recently proposed reinterpretation of gravitational wave memory that builds up on the definition of gravitational waves pioneered by Isaacson, we provide a unifying fram…

Constraining superluminal Einstein-Ãther 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…
