The impact of evolving dark energy on the Weyl potential measured from the Dark Energy Survey Year 3 data
Benedetta Rosatello, Gen Ye, Maria Berti +3
Measurements from the Dark Energy Survey (DES) Year 3 data have shown that the Weyl potential -- the sum of the spatial and temporal distortions of the geometry -- evolves more slo…

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…

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…
