Stable and causal frames for BDNK hydrodynamics
Jay Armas
We establish the existence of families of linearly stable and causal Bemfica-Disconzi-Noronha-Kovtun (BDNK) frames for arbitrary equation of state and set of physical transport coe…
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…
Instabilities of Thin Black Rings: Closing the Gap
Jay Armas, Enrico Parisini
We initiate the study of dynamical instabilities of higher-dimensional black holes using the blackfold approach, focusing on asymptotically flat boosted black strings and singly-sp…
