S-duality in twistor space [PDF]
, 2012 A bstractIn type IIB string compactifications on a Calabi-Yau threefold, the hypermultiplet moduli space $ {\mathcal{M}_H} $ must carry an isometric action of the modular group SL(2,$ \mathbb{Z} $), inherited from the S-duality symmetry of type IIB ...

Non-Abelian Tensor Multiplet Equations from Twistor Space
, 2012 We establish a Penrose–Ward transform yielding a bijection between holomorphic principal 2-bundles over a twistor space and non-Abelian self-dual tensor fields on six-dimensional flat space-time.

Double-copying self-dual Yang-Mills theory to self-dual gravity on twistor space [PDF]
Journal of High Energy Physics, 2023 We construct a simple Lorentz-invariant action for maximally supersymmetric self-dual Yang-Mills theory that manifests colour-kinematics duality. We also show that this action double-copies to a known action for maximally supersymmetric self-dual gravity.

Celestial w1+∞ Symmetries from Twistor Space [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2021 . We explain how twistor theory represents the self-dual sector of four dimensional gravity in terms of the loop group of Poisson diffeomorphisms of the plane via Penrose’s nonlinear graviton construction.

Invariant distributions and the transport twistor space of closed surfaces [PDF]
Journal of the London Mathematical Society, 2023 We study transport equations on the unit tangent bundle of a closed oriented Riemannian surface and their links to the transport twistor space of the surface (a complex surface naturally tailored to the geodesic vector field).

The 4d/2d correspondence in twistor space and holomorphic Wilson lines [PDF]
Journal of High Energy Physics, 2022 We give an explicit realization of the 4d local operator / 2d conformal block correspondence of Costello and Paquette in the case of gauge theories. This is accomplished by lifting the 4d local operators to non-local operators in twistor space using a ...

Twistor formulation of massless 6D infinite spin fields
Nuclear Physics B, 2021 We construct massless infinite spin irreducible representations of the six-dimensional Poincaré group in the space of fields depending on twistor variables. It is shown that the massless infinite spin representation is realized on the two-twistor fields.

N $$ \mathcal{N} $$ = 7 On-shell diagrams and supergravity amplitudes in momentum twistor space [PDF]
Journal of High Energy Physics, 2020 We derive an on-shell diagram recursion for tree-level scattering amplitudes in N $$ \mathcal{N} $$ = 7 supergravity. The diagrams are evaluated in terms of Grassmannian integrals and momentum twistors, generalising previous results of Hodges in momentum

Ambitwistor strings in six and five dimensions
Journal of High Energy Physics, 2021 Ambitwistor strings are chiral (holomorphic) strings whose target is the space of complex null geodesics, ambitwistor space. We introduce twistor representations of ambitwistor space in 6 and 5 dimensions.

Generalized almost even-Clifford manifolds and their twistor spaces
Complex Manifolds, 2021 Motivated by the recent interest in even-Clifford structures and in generalized complex and quaternionic geometries, we introduce the notion of generalized almost even-Clifford structure. We generalize the Arizmendi-Hadfield twistor space construction on
