Spacetime triple wormhole
Vincent Herr, Aimé Fournier, Andrew J. S Hamilton
We describe a multi-neck spacetime wormhole with a simple metric tensor and a simple injective map without coordinate patching. An intra-universe, non-thin-shell, non-spherically-s…
Mass Inflation in Brans-Dicke gravity
P. P. Avelino, A. J. S. Hamilton, C. A. R. Herdeiro
A detailed non-linear analysis of the internal structure of spherical, charged black holes that are accreting scalar matter is performed in the framework of the Brans-Dicke theory…
Information content of the non-linear matter power spectrum
C. D. Rimes, A. J. S. Hamilton
We use an ensemble of N-body simulations of the currently favoured (concordance) cosmological model to measure the amount of information contained in the non-linear matter power sp…
VOBOZ: An Almost-Parameter-Free Halo-Finding Algorithm
Mark C. Neyrinck, Nickolay Y. Gnedin, Andrew J. S. Hamilton
We have developed an algorithm to find haloes in an N-body dark matter simulation, called VOBOZ (VOronoi BOund Zones), which has as little dependence on free parameters as we can m…
Towards Optimal Measurement of Power Spectra I: Minimum Variance Pair Weighting and the Fisher Matrix
A. J. S. Hamilton
This is the first of a pair of papers which address the problem of measuring the unredshifted power spectrum in optimal fashion from a survey of galaxies, with arbitrary geometry,…
Interpretation of UV Absorption Lines in SN1006
A. J. S. Hamilton, R. A. Fesen, C. -C. Wu +2
We present a theoretical interpretation of the broad silicon and iron UV absorption features observed with the Hubble Space Telescope in the spectrum of the Schweizer-Middleditch s…
