Eccentric Mergers of Intermediate-Mass Black Holes from Evection Resonances in AGN Disks
Diego J. Muñoz, Nicholas C. Stone, Cristobal Petrovich +1
We apply the theory of nonlinear resonance capture to the problem of a black hole binary (BHB) orbiting a supermassive black hole (SMBH) while embedded in the accretion disk of an…
Compact-Object Mergers in the Galactic Center: Evolution in Triaxial Clusters
Mathew W. Bub, Cristobal Petrovich
There is significant observational evidence that a large fraction of galactic centers, including those in the Milky Way and M31, host a supermassive black hole (SMBH) embedded in a…
The impact of vector resonant relaxation on the evolution of binaries near a massive black hole: implications for gravitational wave sources
Adrian S. Hamers, Ben Bar-Or, Cristobal Petrovich +1
Binaries within the sphere of influence of a massive black hole (MBH) in galactic nuclei are susceptible to the Lidov-Kozai (LK) mechanism, which can drive orbits to high eccentric…
Precessional dynamics of black hole triples: binary mergers with near-zero effective spin
Fabio Antonini, Carl L. Rodriguez, Cristobal Petrovich +1
The binary black hole mergers detected by Advanced LIGO/Virgo have shown no evidence of large black hole spins. However, because LIGO/Virgo best measures the effective combination…
Greatly enhanced merger rates of compact-object binaries in non-spherical nuclear star clusters
Cristobal Petrovich, Fabio Antonini
The Milky Way and a significant fraction of galaxies are observed to host a central Massive Black Hole (MBH) embedded in a non-spherical nuclear star cluster. We study the secular…
Long-period thermal oscillations in superfluid millisecond pulsars
Cristobal Petrovich, Andreas Reisenegger
In previous papers, we have shown that, as the rotation of a neutron star slows down, it will be internally heated as a consequence of the progressively changing mix of particles (…
Rotochemical heating with a density-dependent superfluid energy gap in neutron stars
Nicolás González-Jiménez, Cristóbal Petrovich, Andreas Reisenegger
When a rotating neutron star loses angular momentum, the reduction of the centrifugal force makes it contract. This perturbs each fluid element, raising the local pressure and orig…
Rotochemical heating in millisecond pulsars with Cooper pairing
Cristobal Petrovich, Andreas Reisenegger
When a rotating neutron star loses angular momentum, the reduction in the centrifugal force makes it contract. This perturbs each fluid element, raising the local pressure and orig…
Rotochemical heating in millisecond pulsars: modified Urca reactions with uniform Cooper pairing gaps
Cristobal Petrovich, Andreas Reisenegger
Context: When a rotating neutron star loses angular momentum, the reduction in the centrifugal force makes it contract. This perturbs each fluid element, raising the local pressure…
