Ultra-compact X-ray binaries are promising sources for LISA because of their short orbital periods. For such binaries with neutron-star primaries, that have been spun-up by angular momentum donations to ~ms periods, internal quadrupole moments sourced by accretion-built mountains may be large (e.g. in 4U 1728−34 and 4U 1820−30). Such systems may thus be simultaneously visible to LVK/ET and...
LISA will play a crucial role in unveiling the universe of gravitational wave sources, particularly by probing the inspirals and mergers of binary compact objects (BCOs) such as black holes, neutron stars, and white dwarfs over cosmological distances. To fully exploit the wealth of data that LISA will provide, we need accurate predictions for the properties and rates of these binary mergers...
We develop a tool for the analysis of stochastic gravitational wave backgrounds from cosmological first-order phase transitions with LISA: we initiate a template databank for these signals, prototype their searches, and forecast their reconstruction. The templates encompass the gravitational wave signals sourced by bubble collisions, sound waves and turbulence. Accounting for Galactic and...
The Loop Quantum Gravity group at IEM-CSIC studies global quantum effects that may influence the emission of gravitational radiation during the final stages of supermassive black hole coalescence. We use Hamiltonian formalisms that allow us to relate black holes with cosmological backgrounds and establish a correspondence between the quantum field theories for gauge invariants in both cases....
I will review the mechanism for primordial gravitational wave generation in axion-inflation models comprising a gauge sector coupled via a Chern-Simons term. I will survey both the Abelian and non-Abelian cases and provide details on the concrete possibility of primordial black hole production. I will elaborate on specific examples whose gravitational signal is detecteable by LISA.
