Oscillations of Dissipative Neutron Stars: The Impact of Hyperonic Reaction Rates

Suprovo Ghosh, Alexander Haber, Nils Andersson +1

Tidal excitations of stellar oscillation modes during binary neutron-star inspirals offer a powerful probe of the composition of dense matter at supranuclear densities. Chemical eq…

Dynamical tidal response of neutron stars via scattering amplitudes

M. V. S. Saketh, Suprovo Ghosh, Nils Andersson

A key challenge of gravitational-wave physics is distinguishing the nature of compact objects in binary coalescences, in particular whether they are black holes or neutron stars. N…

The tidal response of a relativistic star

Nils Andersson, Rhys Counsell, Fabian Gittins +1

We develop a fully relativistic approach for determining the response of a compact star to a time/frequency dependent (tidal) environment. The strategy involves matching the soluti…

A Reproducible Black Hole-Neutron Star Merger Gallery Example for the Einstein Toolkit

Rahime Matur, Beyhan Karakaş, Roland Haas +3

Black hole-neutron star mergers, together with binary neutron star mergers, are key laboratories for neutron star physics. They enable us to probe merger dynamics imprinted in grav…

ESO Expanding Horizon White Paper: Revealing the properties of matter at supranuclear densities with gravitational waves

Tim Dietrich, Tanja Hinderer, Micaela Oertel +40

Understanding dense matter under extreme conditions is one of the most fundamental puzzles in modern physics. Complex interactions give rise to emergent, collective phenomena. Whil…

The Science of the Einstein Telescope

Adrian Abac, Raul Abramo, Simone Albanesi +485

Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
