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…
LISA and the LISA Science Team
Anna Heffernan, Chiara Caprini, Neil Cornish +19
LISA, the Laser Interferometer Space Antenna, due to launch mid-2035, is a large class space mission by the European Space Agency (ESA). In partnership with NASA and ESA-member sta…
Tests of General Relativity with GW230529: a neutron star merging with a lower mass-gap compact object
Elise M. Sänger, Soumen Roy, Michalis Agathos +16
On May 29, 2023, the LIGO Livingston observatory detected the gravitational-wave signal GW230529_181500 from the merger of a neutron star with a lower mass-gap compact object. Its…
Adiabatic tides in compact binaries on quasi-elliptic orbits: Dynamics at the second-and-a-half relative post-Newtonian order
Quentin Henry, Anna Heffernan
GW200105 is the first gravitational wave detection to show signs of eccentricity, it also is a neutron star - blackhole binary. This raises the need for waveforms that incorporate…
Parameter estimation for the GWTC-4.0 catalog with phenomenological waveform models that include orbital eccentricity and an updated description of spin precession
Yumeng Xu, Jorge Valencia, Héctor Estellés Estrella +11
The GWTC-4.0 catalog of transient gravitational wave signals describes observations made in the first part of the fourth observing run of the LIGO-Virgo-KAGRA (LVK) gravitational w…
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…
