Linearised gravitational radiation in de Sitter spacetime at all multipole orders
Harsh, Omkar Shetye, Amitabh Virmani
We derive the linearised gravitational waves generated by a localised matter source in the Poincare patch of de Sitter spacetime at arbitrary multipole order. The linearised de Sit…
Octupolar Gravitational Radiation in de Sitter Spacetime
Harsh, Omkar Shetye, Amitabh Virmani
We derive the gravitational radiation generated by a localised matter source in de Sitter spacetime at octupolar order in the multipolar expansion, working in generalised harmonic…
Influence Phase of a dS Observer II: Electromagnetism
R. Loganayagam, Omkar Shetye
We extend our proposal for static patch holography made in part I (arXiv:2309.07290) to the case of electromagnetism. Using the on-shell action on de Sitter Schwinger-Keldysh (dS-S…
Influence Phase of a dS Observer I : Scalar Exchange
R. Loganayagam, Omkar Shetye
Inspired by real-time computations in AdS black holes, we propose a method to obtain the influence phase of a cosmological observer by calculating the on-shell action on a doubled…
