Gravitational Waves Will Find Love GWs and g -rays!! GWs test-particles tidal deformations merger Gravitational Waves from Neutron Star Binaries depend on ( l 1 ,Q 1, l 2 ,Q 2 ) 3G Physics Multi-Band I-Love-Q Yunes 18

Somebody will find I Option 1: Use NICER Option 2: Use Binary Pulsars Either NICER or Binary Pulsars will measure the Moment of Inertia 3G Physics Multi-Band I-Love-Q Yunes 19

I-Love-Q Relations [Yagi & Yunes, Science 341 2013, Yagi & Yunes, PRD 88 2013] The moment of inertia, quadrupole moment and Love number satisfy Universal, EoS-independent relations! 3G Physics Multi-Band I-Love-Q Yunes 20

I-Love-Q Test I-Love test leads to strong constraints on modified gravity [Yagi & Yunes, Science 341 2013, Yagi & Yunes, PRD 88 2013, Gupta et al, CQG 2017] 3G Physics Multi-Band I-Love-Q Yunes 21

Conclusions 3G Detectors Will Allow for Precision Tests of GR If it bleeds, (extreme gravity, clean, localized, constraint maps) we can kill it! Multi-Band Observations Will Be Ultimate Test (requires synchronized LISA-Earth Detector effort) I-Love-Q Tests Will Allow Different And Stringent Tests (constraints on parity violation and Lorentz violation) Important Topics I Had To Leave Out: Constraints on Parity violation, on Lorentz violation Quasinormal BH (“hair”) tests Constraints on additional polarizations Yunes 22
