Non-abelian cubic vertices for higher-spin fields in anti-de Sitter space
Nicolas Boulanger, Dmitry Ponomarev, E. D. Skvortsov
We use the Fradkin-Vasiliev procedure to construct the full set of non-abelian cubic vertices for totally symmetric higher spin gauge fields in anti-de Sitter space. The number of…
Construction of oscillatory singularities
Alan D. Rendall
One way to understand more about spacetime singularities is to construct solutions of the Einstein equations containing singularities with prescribed properties. The heuristic idea…
Tidal disruptions in circumbinary discs (I): Star formation, dynamics, and binary evolution
Pau Amaro-Seoane, Patrick Brem, Jorge Cuadra
In our current interpretation of the hierarchical structure of the universe it is well established that galaxies collide and merge with each other during their lifetime. If massive…
On Ricci curvature and volume growth in dimension three
Martin Reiris
We prove that any complete metric on R^3 minus a ball with non-negative Ricci curvature and quadratic Ricci-curvature decay, has cubic volume growth.
Oxidation of self-duality to 12 dimensions and beyond
Chandrashekar Devchand
Using (partial) curvature flows and the transitive action of subgroups of O(d,Z) on the indices {1,...,d} of the components of the Yang-Mills curvature in an orthonormal basis, we…
Anomalous dynamic back-action in interferometers
Sergey P. Tarabrin, Henning Kaufer, Farid Ya. Khalili +2
We analyze the dynamic optomechanical back-action in signal-recycled Michelson and Michelson-Sagnac interferometers that are operated off dark port. We show that in this case --- a…
Relations between canonical and non-canonical inflation
Rhiannon Gwyn, Markus Rummel, Alexander Westphal
We look for potential observational degeneracies between canonical and non-canonical models of inflation of a single field . Non-canonical inflationary models are characterized…
Constraints on anisotropic cosmic expansion from supernovae
Benedict Bahr-Kalus, Dominik J. Schwarz, Marina Seikel +1
We test the isotropy of the expansion of the Universe by estimating the hemispherical anisotropy of supernova type Ia (SN Ia) Hubble diagrams at low redshifts (z<0.2). We compare t…
Wheeler-DeWitt Equation in 3 + 1 Dimensions
Herbert W. Hamber, Reiko Toriumi, Ruth M. Williams
Physical properties of the quantum gravitational vacuum state are explored by solving a lattice version of the Wheeler-DeWitt equation. The constraint of diffeomorphism invariance…
The Ghost Condensate in N=1 Supergravity
Michael Koehn, Jean-Luc Lehners, Burt Ovrut
We present the theory of a supersymmetric ghost condensate coupled to N=1 supergravity. This is accomplished using a general formalism for constructing locally supersymmetric highe…
Target Spaces from Chiral Gauge Theories
Ilarion V. Melnikov, Callum Quigley, Savdeep Sethi +1
Chiral gauge theories in two dimensions with (0,2) supersymmetry are central in the study of string compactifications. Remarkably little is known about generic (0,2) theories. We c…
Harmonic R-matrices for Scattering Amplitudes and Spectral Regularization
Livia Ferro, Tomasz Lukowski, Carlo Meneghelli +2
Planar N=4 super Yang-Mills appears to be integrable. While this allows to find this theory's exact spectrum, integrability has hitherto been of no direct use for scattering amplit…
Generating functions of (partially-)massless higher-spin cubic interactions
Euihun Joung, Luca Lopez, Massimo Taronna
Generating functions encoding cubic interactions of (partially-)massless higher-spin fields are provided within the ambient-space formalism. They satisfy a system of higher-order p…
Interpolation in waveform space: enhancing the accuracy of gravitational waveform families using numerical relativity
Kipp Cannon, J. D. Emberson, Chad Hanna +2
Matched-filtering for the identification of compact object mergers in gravitational-wave antenna data involves the comparison of the data stream to a bank of template gravitational…
Length sensing and control of a Michelson interferometer with Power Recycling and Twin Signal Recycling cavities
Christian Gräf, André Thüring, Henning Vahlbruch +2
The techniques of power recycling and signal recycling have proven as key concepts to increase the sensitivity of large-scale gravitational wave detectors by independent resonant e…
Binary Millisecond Pulsar Discovery via Gamma-Ray Pulsations
H. J. Pletsch, L. Guillemot, H. Fehrmann +150
Millisecond pulsars, old neutron stars spun-up by accreting matter from a companion star, can reach high rotation rates of hundreds of revolutions per second. Until now, all such "…
Blocking low-eccentricity EMRIs: A statistical direct-summation N-body study of the Schwarzschild barrier
Patrick Brem, Pau Amaro-Seoane, Carlos F. Sopuerta
The capture of a compact object in a galactic nucleus by a massive black hole (MBH), an extreme-mass ratio inspiral (EMRI), is the best way to map space and time around it. Recent…
Fake plunges are very eccentric real EMRIs in disguise ... they dominate the rates and are blissfully ignorant of angular momentum barriers
Pau Amaro-Seoane, Carlos Sopuerta, Patrick Brem
The capture of a compact object in a galactic nucleus by a massive black hole (MBH) is the best way to map space and time around it. Compact objects such as stellar black holes on…
Systematic investigation of the expected gravitational wave signal from supermassive black hole binaries in the pulsar timing band
A. Sesana
In this letter we carry out the first systematic investigation of the expected gravitational wave (GW) background generated by supermassive black hole (SMBH) binaries in the nHz fr…
Stability of Einstein-Aether Cosmological Models
Patrik Sandin, Bassemah Alhulaimi, Alan Coley
We use a dynamical systems analysis to investigate the future behaviour of Einstein-Aether cosmological models with a scalar field coupling to the expansion of the aether and a non…
Quantum-Dense Metrology
Sebastian Steinlechner, Jöran Bauchrowitz, Melanie Meinders +3
Quantum metrology utilizes entanglement for improving the sensitivity of measurements. Up to now the focus has been on the measurement of just one out of two non-commuting observab…
Accelerating pulsar timing data analysis
Rutger van Haasteren
The analysis of pulsar timing data, especially in pulsar timing array (PTA) projects, has encountered practical difficulties: evaluating the likelihood and/or correlation-based sta…
Variability from Nonaxisymmetric Fluctuations Interacting with Standing Shocks in Tilted Black Hole Accretion Disks
Ken B. Henisey, Omer M. Blaes, P. Chris Fragile
We study the spatial and temporal behavior of fluid in fully three-dimensional, general relativistic, magnetohydrodynamical simulations of both tilted and untilted black hole accre…
Horizon thermodynamics and composite metrics
Lorenzo Sindoni
We examine the conditions under which the thermodynamic behaviour of gravity can be explained within an emergent gravity scenario, where the metric is defined as a composite operat…
