LAST ORBITS OF BINARY BLACK HOLES [PDF]
International Journal of Modern Physics A, 2002 Binary black hole systems in the pre-coalescence stage are numerically constructed by demanding that the associated spacetime admits a helical Killing vector. Comparison with third order post-Newtonian calculations indicates a rather good agreement until the innermost stable circular orbit.

Numerical Simulations of Black-Hole Spacetimes [PDF]
, 2012 This thesis covers various aspects of the numerical simulation of black-hole spacetimes according to Einstein's general theory of relativity, using the Spectral Einstein Code developed by the Caltech-Cornell-CITA collaboration.

Computing binary black hole merger waveforms using openGR [PDF]
, 2012 textOne of the most important predictions of General Relativity, Einstein’s theory of gravity, is the existence of gravitational radiation. The strongest source of such radiation is expected to come from the merging of black holes.

Accretion Into and Emission from Black Holes [PDF]
, 1976 Analyses are given of various processes involving matter falling into or coming out of black holes. A significant amount of matter may fall into a black hole in a galactic nucleus or in a binary system.

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems
Advanced Functional Materials, EarlyView.Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Black hole attractors and the entropy function in four- and five-dimensional N=2 supergravity [PDF]
, 2007 Extremal black holes in theories of gravity coupled to abelian gauge fields and neutral scalars, such as those arising in the low-energy description of compactifications of string theory on Calabi-Yau manifolds, exhibit the attractor phenomenon: on the ...

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots
Advanced Functional Materials, EarlyView.This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

A Long Period Stellar-mass Black Hole Binary in ω Centauri
The Astrophysical Journal LettersModern simulations of stellar dynamics in globular clusters peg a dominant role for stellar-mass black holes, but direct evidence for black holes in clusters remains limited.

Asymmetric Light Curves of Black Hole Binaries and the Doppler Beaming Effect [PDF]
Journal of Astronomy and Space Sciences, 2002 Black hole binary candidates are known to be composed of a black hole with 10Msolar and a K or M type companion. Because the companion is believed to fill the Roche lobe that is very aspherical, the light curves of black hole binaries are characterized ...
