Spin-Inversion Degeneracies in Restricted Inspiral Waveforms for LISA
Kata Karácsonyi, László Árpád Gergely
Spin inversions appear in several settings. Analytical work predicts a single spin flip during unequal-mass supermassive binary inspiral, while numerical relativity and post-Newton…
Fluid interpretation, Hawking--Ellis classification, and energy conditions of the proper kinetic gravity braiding stress tensor
László Árpád Gergely
We investigate the fluid interpretation, Hawking--Ellis classification, and energy conditions of the proper kinetic gravity braiding contribution to the stress tensor of minimally…
White Paper and Roadmap for Quantum Gravity Phenomenology in the Multi-Messenger Era
R. Alves Batista, G. Amelino-Camelia, D. Boncioli +101
The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions of various possible theories of quantum gravity been put…
GW170817: Measurements of Neutron Star Radii and Equation of State
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1149
On 17 August 2017, the LIGO and Virgo observatories made the first direct detection of gravitational waves from the coalescence of a neutron star binary system. The detection of th…
A flat spectrum candidate for a track-type high energy neutrino emission event, the case of blazar PKS 0723-008
E. Kun, P. L. Biermann, L. Á. Gergely
By cross-correlating both the Parkes Catalogue and the Second Planck Catalogue of Compact Sources with the arrival direction of the track-type neutrinos detected by the IceCube Neu…
Weak and strong field approximations and circular orbits of Kehagias-Sfetsos space-time
M. Dwornik, Zs. Horváth, L. Á. Gergely
The Kehagias-Sfetsos asymptotically flat black hole and naked singularity solutions of Hořava-Lifshitz gravity are investigated both in the weak-field and strong-field regimes. In…
Rotation curves in Bose-Einstein Condensate Dark Matter Halos
M. Dwornik, Z. Keresztes, L. Á. Gergely
The study of the rotation curves of spiral galaxies reveals a nearly constant cored density distribution of Cold Dark Matter. N-body simulations however lead to a cuspy distributio…
Search for long-lived gravitational-wave transients coincident with long gamma-ray bursts
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +875
Long gamma-ray bursts (GRBs) have been linked to extreme core-collapse supernovae from massive stars. Gravitational waves (GW) offer a probe of the physics behind long GRBs. We inv…
Parameter estimation for compact binary coalescence signals with the first generation gravitational-wave detector network
the LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +801
Compact binary systems with neutron stars or black holes are one of the most promising sources for ground-based gravitational wave detectors. Gravitational radiation encodes rich i…
The paradox of soft singularity crossing avoided by distributional cosmological quantities
A. Kamenshchik, Z. Keresztes, L. Gergely
A flat Friedmann universe filled with a mixture of anti-Chaplygin gas and dust-like matter evolves into a future soft singularity, where despite infinite tidal forces the geodesics…
Testing General Relativity With Laser Accelerated Electron Beams
L. Á. Gergely, T. Harko
Electron accelerations of the order of obtained by laser fields open up the possibility of experimentally testing one of the cornerstones of general relativity, the wea…
Weyl fluid dark matter model tested on the galactic scale by weak gravitational lensing
K. C. Wong, T. Harko, K. S. Cheng +1
The higher dimensional Weyl curvature induces on the brane a new source of gravity. This Weyl fluid of geometrical origin (reducing in the spherically symmetric, static configurati…
Search for gravitational waves associated with gamma-ray bursts during LIGO science run 6 and Virgo science runs 2 and 3
The LIGO Scientific Collaboration, Virgo Collaboration, J. Abadie +807
We present the results of a search for gravitational waves associated with 154 gamma-ray bursts (GRBs) that were detected by satellite-based gamma-ray experiments in 2009-2010, dur…
Compact binary waveform recovery from the cross-correlated data of two detectors by matched filtering with spinning templates
L. Veréb, Z. Keresztes, P. Raffai +3
We investigate whether the recovery chances of highly spinning waveforms by matched filtering with randomly chosen spinning waveforms generated with the LAL package are improved by…
3+1+1 dimensional covariant gravitational dynamics on an asymmetrically embedded brane
Zoltán Keresztes, László Á. Gergely
We give the evolution and constraint equations on an asymmetrically embedded brane in the form of average and difference equations.
Do supernovae favor tachyonic Big Brake instead de Sitter?
L. Á. Gergely, Z. Keresztes, A. Yu. Kamenshchik +2
We investigate whether a tachyonic scalar field, encompassing both dark energy and dark matter-like features will drive our universe towards a Big Brake singularity or a de Sitter…
Active Galactic Nuclei: Sources for ultra high energy cosmic rays?
P. L. Biermann, J. K. Becker, L. Caramete +11
The origin of ultra high energy cosmic rays promises to lead us to a deeper understanding of the structure of matter. This is possible through the study of particle collisions at c…
Orbital phase in inspiralling compact binaries
Mátyás Vasúth, Balázs Mikóczi, László Á. Gergely
We derive the rate of change of the mean motion up to the second post-Newtonian order for inspiralling compact binaries with spin, mass quadrupole and magnetic dipole moments on ec…
