Null fluid/gravity correspondence
Jay Armas, Emil Have, Gianbattista-Piero Nicosia
We construct a new class of perturbative asymptotically Anti-de Sitter pp-wave spacetimes by performing a long-wavelength expansion of Kaigorodov metrics in arbitrary spacetime dim…

Null matter and the ultrarelativistic origin of hydrodynamics at zero temperature
Jay Armas, Emil Have, Gianbattista-Piero Nicosia
We uncover a universal sector of relativistic fluid dynamics by taking a novel ultrarelativistic limit in which the temperature tends to zero while the flow simultaneously approach…

New asymptotically (Anti)-de Sitter black holes in (super)gravity
Jay Armas, Gianbattista-Piero Nicosia
We use the duality between gravitational dynamics and fluids living on dynamical surfaces carrying multiple charges, known as the blackfold approach, to perturbativaly construct ne…
