Formulation Improvements for Critical Collapse Simulations
Daniela Cors, Sarah Renkhoff, Hannes R. Rüter +2
The precise tuning required to observe critical phenomena in gravitational collapse poses a challenge for most numerical codes. First, threshold estimation searches may be obstruct…
Spin effects in gravitational waveforms and fluxes for binaries on eccentric orbits to the third post-Newtonian order
Quentin Henry, Mohammed Khalil
Compact binaries can have non-negligible orbital eccentricities in the frequency band of ground-based gravitational-wave detectors, depending on their astrophysical formation chann…
Theoretical groundwork supporting the precessing-spin two-body dynamics of the effective-one-body waveform models SEOBNRv5
Mohammed Khalil, Alessandra Buonanno, Héctor Estellés +4
Waveform models are essential for gravitational-wave (GW) detection and parameter estimation of coalescing compact-object binaries. More accurate models are required for the increa…
Spin contributions to the gravitational-waveform modes for spin-aligned binaries at the 3.5PN order
Quentin Henry, Sylvain Marsat, Mohammed Khalil
We complete the post-Newtonian (PN) prediction at the 3.5PN order for the spin contributions to the gravitational waveforms emitted by inspiraling compact binaries, in the case of…
Effective-action model for dynamical scalarization beyond the adiabatic approximation
Mohammed Khalil, Raissa F. P. Mendes, Néstor Ortiz +1
In certain scalar-field extensions to general relativity, scalar charges can develop on compact objects in an inspiraling binary -- an effect known as dynamical scalarization. This…
Snowmass White Paper: Gravitational Waves and Scattering Amplitudes
Alessandra Buonanno, Mohammed Khalil, Donal O'Connell +3
We review recent progress and future prospects for harnessing powerful tools from theoretical high-energy physics, such as scattering amplitudes and effective field theory, to deve…
Energetics and scattering of gravitational two-body systems at fourth post-Minkowskian order
Mohammed Khalil, Alessandra Buonanno, Jan Steinhoff +1
Upcoming observational runs of the LIGO-Virgo-KAGRA collaboration, and future gravitational-wave (GW) detectors on the ground and in space, require waveform models more accurate th…
Effective-one-body multipolar waveforms for eccentric binary black holes with non-precessing spins
Antoni Ramos-Buades, Alessandra Buonanno, Mohammed Khalil +1
We construct an inspiral-merger-ringdown eccentric gravitational-wave (GW) model for binary black holes with non-precessing spins within the effective-one-body formalism. This wave…
Gravitational spin-orbit dynamics at the fifth-and-a-half post-Newtonian order
Mohammed Khalil
Accurate waveform models are crucial for gravitational-wave data analysis, and since spin has a significant effect on the binary dynamics, it is important to improve the spin descr…
Radiation-reaction force and multipolar waveforms for eccentric, spin-aligned binaries in the effective-one-body formalism
Mohammed Khalil, Alessandra Buonanno, Jan Steinhoff +1
While most binary inspirals are expected to have circularized before they enter the LIGO/Virgo frequency band, a small fraction of those binaries could have non-negligible orbital…
The Field Substellar Mass Function Based on the Full-sky 20-pc Census of 525 L, T, and Y Dwarfs
J. Davy Kirkpatrick, Christopher R. Gelino, Jacqueline K. Faherty +49
We present final Spitzer trigonometric parallaxes for 361 L, T, and Y dwarfs. We combine these with prior studies to build a list of 525 known L, T, and Y dwarfs within 20 pc of th…
Gravitational spin-orbit and aligned spin-spin couplings through third-subleading post-Newtonian orders
Andrea Antonelli, Chris Kavanagh, Mohammed Khalil +2
The study of scattering encounters continues to provide new insights into the general relativistic two-body problem. The local-in-time conservative dynamics of an aligned-spin bina…
Gravitational spin-orbit coupling through third-subleading post-Newtonian order: from first-order self-force to arbitrary mass ratios

Exploiting simple yet remarkable properties of relativistic gravitational scattering, we use first-order self-force (linear-in-mass-ratio) results to obtain arbitrary-mass-ratio re…
Fourth post-Newtonian effective-one-body Hamiltonians with generic spins

In a compact binary coalescence, the spins of the compact objects can have a significant effect on the orbital motion and gravitational-wave (GW) emission. For generic spin orienta…

Gravitational wave observations can provide unprecedented insight into the fundamental nature of gravity and allow for novel tests of modifications to General Relativity. One propo…
Hairy binary black holes in Einstein-Maxwell-dilaton theory and their effective-one-body description
Mohammed Khalil, Noah Sennett, Jan Steinhoff +2
In General Relativity and many modified theories of gravity, isolated black holes (BHs) cannot source massless scalar fields. Einstein-Maxwell-dilaton (EMd) theory is an exception:…
