The holographic dual of the Penrose transform
Journal of High Energy Physics, 2018 We consider the holographic duality between type-A higher-spin gravity in AdS4 and the free U(N) vector model. In the bulk, linearized solutions can be translated into twistor functions via the Penrose transform.

Journal of High Energy Physics, 2023 We elaborate on various aspects of our top-down celestial holographic duality wherein the semiclassical bulk spacetime is a 4d asymptotically flat, self-dual Kähler geometry known as Burns space.

Philosophical Aspects of Astrobiology Revisited
Philosophies, 2021 Given the idea that Life as we know it is nothing but a special form of a generically underlying dynamical structure within the physical Universe, we try to introduce a concept of Life that is not only derived from first principles of fundamental physics,

One-loop corrections to the celestial chiral algebra from Koszul Duality
Journal of High Energy Physics, 2023 We consider self-dual Yang-Mills theory (SDYM) in four dimensions and its lift to holomorphic BF theory on twistor space. Following the work of Costello and Paquette, we couple SDYM to a quartic axion field, which guarantees associativity of the ...

Twistor Theory of the Airy Equation [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2014 We demonstrate how the complex integral formula for the Airy functions arises from Penrose's twistor contour integral formula. We then use the Lax formulation of the isomonodromy problem with one irregular singularity of order four to show that the Airy equation arises from the anti-self-duality equations for conformal structures of neutral signature ...

4D higher spin black holes with nonlinear scalar fluctuations
Journal of High Energy Physics, 2017 We construct an infinite-dimensional space of solutions to Vasiliev’s equations in four dimensions that are asymptotic to AdS spacetime and superpose massless scalar particle modes over static higher spin black holes. Each solution is obtained by a large

Bulk interactions and boundary dual of higher-spin-charged particles
Journal of High Energy Physics, 2021 We consider higher-spin gravity in (Euclidean) AdS 4 , dual to a free vector model on the 3d boundary. In the bulk theory, we study the linearized version of the Didenko-Vasiliev black hole solution: a particle that couples to the gauge fields of all ...

Spinorial higher-spin gauge theory from IKKT model in Euclidean and Minkowski signatures
Journal of High Energy Physics, 2023 We explore the semi-classical relation between the fuzzy 4-hyperboloid H N 4 $$ {H}_N^4 $$ and non-compact quantized twistor space ℙ N 1 , 2 $$ {\mathbb{P}}_N^{1,2} $$ at large N.

Complete Equivalence Between Gluon Tree Amplitudes in Twistor String Theory and in Gauge Theory [PDF]
, 2011 The gluon tree amplitudes of open twistor string theory, defined as contour integrals over the ACCK link variables, are shown to satisfy the BCFW relations, thus confirming that they coincide with the corresponding amplitudes in gauge field theory.

Twistor strings for N $$ \mathcal{N} $$ = 8 supergravity
Journal of High Energy Physics, 2020 This paper presents a worldsheet theory describing holomorphic maps to twistor space with N $$ \mathcal{N} $$ fermionic directions. The theory is anomaly free when N $$ \mathcal{N} $$ = 8.
