Applying full polarization A-Projection to very wide field of view instruments: An imager for LOFAR
C. Tasse, B. van der Tol, J. van Zwieten +2
The aimed high sensitivities and large fields of view of the new generation of interferometers impose to reach high dynamic range of order 1: to 1: in the case of…
Three-Dimensional General-Relativistic Hydrodynamic Simulations of Binary Neutron Star Coalescence and Stellar Collapse with Multipatch Grids
C. Reisswig, R. Haas, C. D. Ott +4
We present a new three-dimensional general-relativistic hydrodynamic evolution scheme coupled to dynamical spacetime evolutions which is capable of efficiently simulating stellar c…
Lovelock gravity is equivalent to Einstein gravity coupled to form fields
Ram Brustein, A. J. M. Medved
Lovelock gravity is a class of higher-derivative gravitational theories whose linearized equations of motion have no more than two time derivatives. Here, it is shown that any Love…
Graviton multi-point functions at the AdS boundary
Ram Brustein, A. J. M. Medved
The gauge-gravity duality can be used to relate connected multi-point graviton functions to connected multi-point correlation functions of the stress tensor of a strongly coupled f…
Radio Continuum Surveys with Square Kilometre Array Pathfinders
Ray P. Norris, J. Afonso, D. Bacon +48
In the lead-up to the Square Kilometre Array (SKA) project, several next-generation radio telescopes and upgrades are already being built around the world. These include APERTIF (T…
M87 at metre wavelengths: the LOFAR picture
F. de Gasperin, E. Orru', M. Murgia +92
M87 is a giant elliptical galaxy located in the centre of the Virgo cluster, which harbours a supermassive black hole of mass 6.4x10^9 M_sun, whose activity is responsible for the…
