One-form superfluids and magnetohydrodynamics [PDF]
, 2020 We use the framework of generalised global symmetries to study various hydrodynamic regimes of hot electromagnetism. We formulate the hydrodynamic theories with an unbroken or a spontaneously broken U(1) one-form symmetry. The latter of these describes a

How Fluids Bend: the Elastic Expansion for Higher-Dimensional Black Holes [PDF]
, 2013 Hydrodynamics can be consistently formulated on surfaces of arbitrary co-dimension in a background space-time, providing the effective theory describing long-wavelength perturbations of black branes. When the co-dimension is non-zero, the system acquires

New Geometries for Black Hole Horizons [PDF]
, 2015 We construct several classes of worldvolume effective actions for black holes by integrating out spatial sections of the worldvolume geometry of asymptotically flat black branes.

Blackfolds, Plane Waves and Minimal Surfaces [PDF]
, 2015 Minimal surfaces in Euclidean space provide examples of possible non-compact horizon geometries and topologies in asymptotically flat space-time. On the other hand, the existence of limiting surfaces in the space-time provides a simple mechanism for ...

The X-ray spectral properties of very-faint persistent neutron star X-ray binaries [PDF]
, 2013 AX J1754.2-2754, 1RXS J171824.2-402934 and 1RXH J173523.7-354013 are three persistent neutron star low-mass X-ray binaries that display a 2--10 keV accretion luminosity Lx of only (1-10)x1E34 erg s-1 (i.e., only ~0.005-0.05 % of the Eddington limit). The

Constraints on the effective fluid theory of stationary branes [PDF]
, 2014 We develop further the effective fluid theory of stationary branes. This formalism applies to stationary blackfolds as well as to other equilibrium brane systems at finite temperature.

Extremal Black Hole Horizons [PDF]
, 2018 Using the blackfold effective theory applied to extremal Kerr branes we provide evidence for the existence of new stationary extremal black hole solutions in asymptotically flat spacetime with both single and multiple disconnected horizons. These include

XMM-Newton and Swift spectroscopy of the newly discovered very-faint X-ray transient IGR J17494-3030 [PDF]
, 2013 A growing group of low-mass X-ray binaries are found to be accreting at very-faint X-ray luminosities of

La evolución del porte y tenencia legal de armas en Colombia [PDF]
, 2021 En la historia de la humanidad, las personas han utilizado diferentes herramientas e instrumentos con la finalidad de ejercer un daño o una amenaza a la integridad física de otro ser, ya sea para cazar, para defenderse, para confrontamientos y peleas ...

Null-Wave Giant Gravitons from Thermal Spinning Brane Probes [PDF]
, 2013 We construct and analyze thermal spinning giant gravitons in type II/M-theory based on spherically wrapped black branes, using the method of thermal probe branes originating from the blackfold approach.
