Metric reconstruction from celestial multipoles
Geoffrey Compère, Roberto Oliveri, Ali Seraj
The most general vacuum solution to Einstein's field equations with no incoming radiation can be constructed perturbatively from two infinite sets of canonical multipole moments, w…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Evolving black hole with scalar field accretion
Marco de Cesare, Roberto Oliveri
We obtain approximate analytical solutions of the Einstein equations close to the trapping horizon for a dynamical spherically symmetric black hole in the presence of a minimally c…
Blandford--Znajek monopole expansion revisited: novel non-analytic contributions to the power emission
Filippo Camilloni, Oscar J. C. Dias, Gianluca Grignani +5
The Blandford and Znajek (BZ) split-monopole serves as an important theoretical example of the mechanism that can drive the electromagnetic extraction of energy from Kerr black hol…
Asymptotic dynamics and charges for FLRW spacetimes
Martin Enriquez-Rojo, Till Heckelbacher, Roberto Oliveri
We investigate the asymptotia of decelerating and spatially flat FLRW spacetimes at future null infinity. We find that the asymptotic algebra of diffeomorphisms can be enlarged to…
