Gravitational Atoms from Topological Stars
Ibrahima Bah, Emanuele Berti, Bogdan Ganchev +2
We study the bound states of a massive scalar field around a topological star, and show that these are strictly normal modes. This yields a genuine gravitational atom, sharply dist…

Extreme mass ratio inspirals in dark matter halos: dynamics and distinguishability of halo models
Sara Gliorio, Emanuele Berti, Andrea Maselli +1
The gravitational wave (GW) signals from extreme mass-ratio inspirals (EMRIs), a key target for the Laser Interferometer Space Antenna (LISA), will be affected in the presence of d…

Extreme mass ratio inspirals in rotating dark matter spikes
Soumodeep Mitra, Nicholas Speeney, Sumanta Chakraborty +1
Gravitational wave (GW) signals from extreme mass ratio inspirals (EMRIs) are a key observational target for the Laser Interferometer Space Antenna (LISA). The waveforms may be aff…
