Gravitational Waves from Hyperbolic Encounters of Primordial Black Holes in Dwarf Galaxies
Tadeo D. Gòmez-Aguilar, Encieh Erfani, N. M. Jimènez Cruz
We investigate the stochastic gravitational wave background (SGWB) generated by primordial black holes (PBHs) in the dense cores of dwarf galaxies (DGs), considering both hierarchi…

Measuring the circular polarization of gravitational waves with pulsar timing arrays
N. M. Jiménez Cruz, Ameek Malhotra, Gianmassimo Tasinato +1
The circular polarization of the stochastic gravitational wave background (SGWB) is a key observable for characterising the origin of the signal detected by Pulsar Timing Array (PT…

Measuring kinematic anisotropies with pulsar timing arrays
N. M. Jiménez Cruz, Ameek Malhotra, Gianmassimo Tasinato +1
Recent Pulsar Timing Array (PTA) collaborations show strong evidence for a stochastic gravitational wave background (SGWB) with the characteristic Hellings-Downs inter-pulsar corre…
