We review recent progress on the information paradox. We explain why exponentially small
correlations in the radiation emitted by a black hole are sufficient to resolve the original …

Celestial holography proposes a duality between the gravitational $\mathcal {S} $-matrix
and correlators in a conformal field theory living on the celestial sphere. In this white paper …

A bstract The double copy suggests that the basis of the dynamics of general relativity is
Yang-Mills theory. Motivated by the importance of the relativistic two-body problem, we study …

A bstract We give a double copy construction for the symmetries of the self-dual sectors of
Yang-Mills (YM) and gravity, in the light-cone formulation. We find an infinite set of double …

These notes are a transcript of lectures given by the author in the XVIII Modave summer
school in mathematical physics. The introduction is devoted to a detailed review of the …

We derive the soft effective action in (d+ 2)-dimensional Abelian gauge theories from the on-
shell action obeying Neumann boundary conditions at timelike and null infinity and Dirichlet …

A bstract We investigate asymptotic symmetries in flat backgrounds of dimension higher than
or equal to four. For spin two we provide the counterpart of the extended BMS …

A bstract We study the renormalized action and the renormalized presymplectic potential for
Maxwell fields on Anti de Sitter backgrounds of any dimensions. We then use these results …

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 BFSS proposed that asymptotically flat M-theory is dual to a large N limit of the
matrix quantum mechanics describing N nonrelativistic D0-branes. Recent insights on the …
