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…

A stepping stone toward detecting gravitational wave memory: a cumulative analysis with the full spherical harmonic using events from GWTC-4.0 and GWTC-5.0

Maria Rosselló-Sastre, Sascha Husa, Yumeng Xu +3

We perform Bayesian model selection to test for the presence of the spherical harmonic mode in gravitational wave events that have previously been identified as bina…

Waveform Modelling for the Laser Interferometer Space Antenna

LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144

LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…

Remnant recoil and host environments of GWTC-4.0 binary black-hole mergers

Joan Llobera-Querol, Eleanor Hamilton, Neha Singh +8

Determining the astrophysical origin of binary black holes and whether merger remnants are retained in their birth environments is essential for understanding hierarchical mergers…

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…
