Gravitational wave memory of compact binary coalescence in the presence of matter effects

Understand

Binary neutron stars (BNSs) and neutron star--black hole (NSBH) binaries are two of the most promising gravitational wave (GW) sources to probe matter effects.

• Upcoming observing runs of LIGO-Virgo-KAGRA detectors and future third generation detectors like Einstein Telescope and Cosmic Explorer will allow the extraction of detailed information on these matter effects from the GW signature of BNS and NSBH systems.
• One subtle effect which may be helpful to extract more information from the detection of compact binary systems is the nonlinear memory.
• In this work, we investigate the observational consequences of gravitational wave nonlinear memory in the presence of matter effects.
