Impact of ultralight bosonic dark matter on the dynamical bar-mode instability of rotating neutron stars
Fabrizio Di Giovanni, Nicolás Sanchis-Gual, Davide Guerra +3
We investigate the effects ultralight bosonic field dark matter may have on the dynamics of unstable differentially-rotating neutron stars prone to the bar-mode instability. To thi…
Fermion-axion stars: static solutions and dynamical stability
Fabrizio Di Giovanni, Davide Guerra, Simone Albanesi +2
We construct spherically-symmetric static solutions of the Einstein-Klein-Gordon-Euler system involving a complex scalar field governed by a periodic potential which emerges in mod…
Can fermion-boson stars reconcile multi-messenger observations of compact stars?
Fabrizio Di Giovanni, Nicolas Sanchis-Gual, Pablo Cerdá-Durán +1
Mixed fermion-boson stars are stable, horizonless, everywhere regular solutions of the coupled Einstein-(complex, massive) Klein-Gordon-Euler system. While isolated neutron stars a…
Searches for continuous gravitational waves from young supernova remnants in the early third observing run of Advanced LIGO and Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1588
We present results of three wide-band directed searches for continuous gravitational waves from 15 young supernova remnants in the first half of the third Advanced LIGO and Virgo o…
Multi-field, multi-frequency bosonic stars and a stabilization mechanism
Nicolas Sanchis-Gual, Fabrizio Di Giovanni, Carlos Herdeiro +2
Scalar bosonic stars (BSs) stand out as a multi-purpose model of exotic compact objects. We enlarge the landscape of such (asymptotically flat, stationary, everywhere regular) obje…
On the dynamical bar-mode instability in spinning bosonic stars
Fabrizio Di Giovanni, Nicolas Sanchis-Gual, Pablo Cerdá-Durán +4
Spinning bosonic stars (SBSs) can form from the gravitational collapse of a dilute cloud of scalar/Proca particles with non-zero angular momentum. In a recent work we found that th…
GW190521: A Binary Black Hole Merger with a Total Mass of
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1253
On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio…
