Celestial Mellin Amplitudes
Francesca Pacifico, Paolo Pergola, Charlotte Sleight
Holographic correlators on the celestial sphere of Minkowski space were recently defined in arXiv:2301.01810 as the extrapolation of bulk time-ordered correlation functions to the…
Cosmological Correlators for Bogoliubov Initial States
Alistair J. Chopping, Charlotte Sleight, Massimo Taronna
We consider late-time correlators in de Sitter (dS) space for initial states related to the Bunch-Davies vacuum by a Bogoliubov transformation. We propose to study such late-time c…
Celestial Holography Revisited II: Correlators and Källén-Lehmann
Lorenzo Iacobacci, Charlotte Sleight, Massimo Taronna
In this work we continue the investigation of the extrapolate dictionary for celestial holography recently proposed in [2301.01810], at both the perturbative and non-perturbative l…
