Inspiral-merger-ringdown waveforms of spinning, precessing black-hole binaries in the effective-one-body formalism [PDF]
, 2013 We describe a general procedure to generate spinning, precessing waveforms that include inspiral, merger and ringdown stages in the effective-one-body (EOB) approach.

Linear Algebra and its Applications, 2015 Let \(H\) be a separable complex Hilbert space and let \(B(H)\) be the Banach algebra of all bounded linear operators on \(H\). The numerical range of \(S\in B(H)\) is the set \(W(S)=\left\{(Sx,x):\; ||x||\; =1\right\}\). It is known that the spectrum \(\sigma (S)\) of \(S\) is contained in \(W(S)\). In this paper, the authors define a more general set,

Weak Gravitation in the 4+1 Formalism
Universe, 2022 The 4+1 formalism in general relativity (GR) prescribes field equations for the spacetime metric γμνx,τ which is local in the spacetime coordinates x and evolves according to an external “worldtime” τ.

NUMERICAL RELATIVITY IN HIGHER DIMENSIONS [PDF]
International Journal of Modern Physics D, 2013 We present an overview of recent developments in numerical relativity studies of higher dimensional spacetimes with a focus on time evolutions of black hole (BH) systems. After a brief review of the numerical techniques employed for these studies, we summarize results grouped into the following three areas: (i) numerical studies of fundamental ...

Characteristic Evolution and Matching
Living Reviews in Relativity, 2001 I review the development of numerical evolution codes for general relativity based upon the characteristic initial value problem. Progress is traced from the early stage of 1D feasibility studies to current 3D codes that simulate binary black holes.

Falloff of the Weyl scalars in binary black hole spacetimes
, 2011 The peeling theorem of general relativity predicts that the Weyl curvature scalars Psi_n (n=0...4), when constructed from a suitable null tetrad in an asymptotically flat spacetime, fall off asymptotically as r^(n-5) along outgoing radial null geodesics.

Numerical relativity and the early Universe
EPJ Web of Conferences, 2016 We consider numerical simulations in general relativity in ADM formalism with cosmological ansatz for the metric. This ansatz is convenient for investigations of the Universe creation in laboratory with Galileons.
