Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

The third Gravitational-Wave Transient Catalog (GWTC-3) describes signals detected with
Advanced LIGO and Advanced Virgo up to the end of their third observing run. Updating the …

PSR J0740+ 6620 has a gravitational mass of 2.08±0.07 M⊙, which is the highest reliably
determined mass of any neutron star. As a result, a measurement of its radius will provide …

The advent of gravitational waves and black hole imaging has opened a new window into
probing the horizon scale of black holes. An important question is whether string theory …

We study an impact of self-interacting bosonic dark matter (DM) on various observable
properties of neutron stars (NSs). The analysis is performed for asymmetric DM with masses …

We show that rotating black holes do not experience any tidal deformation when they are
perturbed by a weak and adiabatic gravitational field. The tidal deformability of an object is …

A bstract It was shown recently that the static tidal response coefficients, called Love
numbers, vanish identically for Kerr black holes in four dimensions. In this work, we confirm …

We extract the black hole (BH) static tidal deformability coefficients (Love numbers) and their
spin-0 and spin-1 analogs by comparing on-shell amplitudes for fields to scatter off a …

We match scattering amplitudes in point particle effective field theory (EFT) and general
relativity to extract low frequency dynamical tidal responses of rotating (Kerr) black holes to …
