Astrometric constraints on stochastic gravitational wave background with neural networks
Marienza Caldarola, Gonzalo Morrás, Santiago Jaraba +3
Astrometric measurements provide a unique avenue for constraining the stochastic gravitational wave background (SGWB). In this work, we investigate the application of two neural ne…
Effects of dynamical capture on two equal-mass nonspinning black holes
Jorge L. RodrÃguez-Monteverde, Santiago Jaraba, Juan GarcÃa-Bellido
Dynamical captures of black holes are unique events that provide an exceptional opportunity to probe the strong-field regime of gravitational physics. In this article, we perform n…
Numerical simulations of oscillating and differentially rotating neutron stars
Santiago Jaraba, Jérôme Novak, Micaela Oertel
The remnants of binary neutron star mergers are expected to be massive, rapidly rotating stars whose oscillations produce gravitational waves in the kilohertz band. The degree of d…
First astrometric constraints on parity-violation in the gravitational wave background
Santiago Jaraba, Sachiko Kuroyanagi, Qiuyue Liang +2
Astrometry, the precise measurement of stellar positions and velocities, offers a promising approach to probing the low-frequency stochastic gravitational wave background (SGWB). N…
