Secular momentum transport by gravitational waves from spinning compact binaries
Zoltán Keresztes, Balázs Mikóczi, László Á. Gergely +1
We present a closed system of coupled first order differential equations governing the secular linear momentum loss of a compact binary due to emitted gravitational waves, with the…
Recovering a spinning inspiralling compact binary waveform immersed in LIGO-like noise with spinning templates
László Veréb, Zoltán Keresztes, Péter Raffai +2
We investigate the recovery chances of highly spinning waveforms immersed in LIGO S5-like noise by performing a matched filtering with 10^6 randomly chosen spinning waveforms gener…
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…
Renormalized spin coefficients in the accumulated orbital phase for unequal mass black hole binaries
László Á. Gergely, Peter L. Biermann, Balázs Mikóczi +1
We analyze galactic black hole mergers and their emitted gravitational waves. Such mergers have typically unequal masses with mass ratio of the order 1/10. The emitted gravitationa…
Covariant gravitational dynamics in 3+1+1 dimensions
Zoltán Keresztes, László Á. Gergely
We develop a 3+1+1 covariant formalism with cosmological and astrophysical applications. First we give the evolution and constraint equations both on the brane and off-brane in ter…
Second-order light deflection by tidal charged black holes on the brane
László Á. Gergely, Zoltán Keresztes, Marek Dwornik
We derive the deflection angle of light rays passing near a black hole with mass m and tidal charge q, confined to a generalized Randall-Sundrum brane with codimension one. We empl…
