A bstract Soft graviton theorems receive one-loop contributions that are logarithmic in the
energy of the soft graviton, and which are closely related to tails of gravitational waveforms …

A bstract In a companion paper [1] we introduced the notion of asymptotically Minkowski
spacetimes. These space-times are asymptotically flat at both null and spatial infinity, and …

A bstract The Spi framework provides a 4-dimensional approach to investigate the
asymptotic properties of gravitational fields as one recedes from isolated systems in any …

We propose a consistent set of boundary conditions for gravity in asymptotically flat
spacetime at spacelike infinity, which yields an enhancement of the Bondi-Metzner-Sachs …

A bstract We use tools from conformal representation theory to classify the symmetries
associated to conformally soft operators in celestial CFT (CCFT) in general dimensions d …

A bstract We present a new formalism to solve the kinematical constraints due to Weyl
invariance for CFTs in curved backgrounds and/or non-trivial states, and we apply it to …

In this review article, we revisit the connection between dressing of scattering states in
quantum electrodynamics by clouds of soft photons, and their dressing by (generalised) …

A bstract We perform a complete and systematic analysis of the solution space of six-
dimensional Einstein gravity. We show that a particular subclass of solutions—those that are …

A bstract We discuss the emergence of a new symmetry generator in a Hamiltonian
realisation of four-dimensional gauge theories in the flat space foliated by retarded …
