Divergent Energy-Momentum Fluxes In Nonlocal Gravity Models
Yi-Zen Chu, Afidah Zuroida
We analyze the second order perturbations of the Deser-Woodard II (DWII), Vardanyan-Akrami-Amendola-Silvestri (VAAS) and Amendola-Burzilla-Nersisyan (ABN) nonlocal gravity models i…

Scalar Gravitational Waves Can Be Generated Even Without Direct Coupling Between Dark Energy and Ordinary Matter
Li-Ying Chou, Yi-Zen Chu, Yen-Wei Liu
We point out, the scalar sector of gravitational perturbations may be excited by an isolated astrophysical system immersed in a universe whose accelerated expansion is not due to t…

Gravitational Wave Memory In dS and 4D Cosmology
Yi-Zen Chu
We argue that massless gravitons in all even dimensional de Sitter (dS) spacetimes higher than two admit a linear memory effect arising from their propagation inside the null cone.…
