Constraints on gravitational waves from the 2024 Vela pulsar glitch
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1774
Among known neutron stars, the Vela pulsar is one of the best targets for gravitational-wave searches. It is also one of the most prolific in terms of glitches, sudden frequency ch…
Twist-free axisymmetric critical collapse of a complex scalar field
Krinio Marouda, Daniela Cors, Hannes R. Rüter +2
Critical phenomena in gravitational collapse are characterized by the emergence of surprising structure in solution space, namely the appearance of universal power-laws and periodi…
Next-to-leading order spin-orbit and spin(a)-spin(b) Hamiltonians for n gravitating spinning compact objects
Johannes Hartung, Jan Steinhoff
We derive the post-Newtonian next-to-leading order conservative spin-orbit and spin(a)-spin(b) gravitational interaction Hamiltonians for arbitrary many compact objects. The spin-o…
Fourth-post-Newtonian-exact approximation to General Relativity
David Brizuela, Gerhard Schaefer
An approximation to General Relativity is presented that agrees with the Einstein field equations up to and including the fourth post-Newtonian (PN) order. This approximation is fo…
Comment on recent papers regarding next-to-leading order spin-spin effects in gravitational interaction
Jan Steinhoff, Gerhard Schäfer
It is argued that the tetrad in a recent paper by Porto and Rothstein on gravitational spin-spin coupling should not have the given form. The fixation of that tetrad was suggested…
Accurate and efficient gravitational waveforms for certain galactic compact binaries
Manuel Tessmer, Achamveedu Gopakumar
Stellar-mass compact binaries in eccentric orbits are almost guaranteed sources of gravitational waves for Laser Interferometer Space Antenna. We present a prescription to compute…
