LIGO A: Detector Design and Science Prospects Beyond A+
L. Sun, K. Kuns, B. J. J. Slagmolen +1153
We present the LIGO A detector concept, an upgrade for the LIGO observatories based on room-temperature interferometers beyond the fifth observing run (O5). Building on th…
Establishing Compactness as a Population Observable in Gravitational-Wave Astronomy
Shrobana Ghosh, Charlie Hoy, Mark Hannam +1
Classically, black holes (BHs) are the most compact objects predicted in nature with C=0.5 in the Schwarzschild limit; C is defined as the mass-to-radius ratio in geometric units.…
Compactness Inference in Gravitational-Wave Mergers with PhenomDECO: Catalog Benchmarks and Robustness Diagnostics
Shrobana Ghosh, Charlie Hoy, Mark Hannam +1
Several gravitational wave (GW) observations have been identified as binary black hole (BBH) mergers, including systems with component masses that challenge typical formation scena…
A pipeline to search for signatures of line-of-sight acceleration in gravitational wave signals produced by compact binary coalescences
Avinash Tiwari, Aditya Vijaykumar, Shasvath J. Kapadia +2
Compact binary coalescences (CBCs), such as merging binary black holes (BBHs), binary neutron stars (BNSs), or neutron star black holes (NSBHs), hosted by dense stellar environment…
On the Identification of Exotic Compact Binaries with Gravitational Waves: a Phenomenological approach
Shrobana Ghosh, Mark Hannam
Gravitational wave (GW) astronomy has been hailed as a gateway to discovering unexpected phenomena in the universe. Over the last decade there have been close to one hundred GW obs…
PhenomXPNR: An improved gravitational wave model linking precessing inspirals and NR-calibrated merger-ringdown
Eleanor Hamilton, Marta Colleoni, Jonathan E. Thompson +10
We present the frequency-domain quasi-circular precessing binary-black-hole model PhenomXPNR. This model combines the most precise available post-Newtonian description of the evolu…
