Tracing out massive fields in cosmology
Guanhao Sun, Sam S. C. Wong
Cosmological correlators are calculated through the in-in formalism in (quasi-)de Sitter background. Its effective description is best represented by a reduced density matrix. In t…
Dynamical nonlinear tails in Schwarzschild black hole ringdown
Siyang Ling, Sabeela Shah, Sam S. C. Wong
Nonlinear tails in black hole perturbations, arising from second-order effects, present a distinct departure from the well-known Price tail of linear theory. We present an analytic…
Gravitational memory and Ward identities in the local detector frame
Valerio De Luca, Justin Khoury, Sam S. C. Wong
Gravitational memory, which describes the permanent shift in the strain after the passage of gravitational waves, is directly related to Weinberg's soft graviton theorems and the B…
Gravitational memory and soft theorems: The local perspective
Valerio De Luca, Justin Khoury, Sam S. C. Wong
In general relativity, gravitational memory describes the lasting change in the separation and relative velocity of freely falling detectors after the passage of gravitational wave…
Probing Parity Violation in the Stochastic Gravitational Wave Background with Astrometry
Qiuyue Liang, Meng-Xiang Lin, Mark Trodden +1
Astrometry holds the potential for testing fundamental physics through the effects of the Stochastic Gravitational Wave Background (SGWB) in the nHz frequency band on…
