New gravitational waveform model for precessing binary neutron stars with double-spin effects
Marta Colleoni, Felip A. Ramis Vidal, Nathan K. Johnson-McDaniel +3
We present two new frequency-domain gravitational waveform models for the analysis of signals emitted by binary neutron star coalescences: IMRPhenomXAS_NRTidalv2 and IMRPhenomXP_NR…
Inferring spin tilts of binary black holes at formation with plus-era gravitational wave detectors
Sumeet Kulkarni, Nathan K. Johnson-McDaniel, Khun Sang Phukon +2
The spin orientations of spinning binary black hole (BBH) mergers detected by ground-based gravitational wave detectors such as LIGO and Virgo can provide important clues about the…
Effect of Ignoring Eccentricity in Testing General Relativity with Gravitational Waves
Purnima Narayan, Nathan K. Johnson-McDaniel, Anuradha Gupta
Detections of gravitational waves emitted from binary black hole coalescences allow us to probe the strong-field dynamics of general relativity (GR). One can compare the observed g…
Distinguishing binary black hole precessional morphologies with gravitational wave observations
Nathan K. Johnson-McDaniel, Khun Sang Phukon, N. V. Krishnendu +1
The precessional motion of binary black holes can be classified into one of three morphologies, based on the evolution of the angle between the components of the spins in the orbit…
