Periodic orbits and their gravitational waves in EMRIs: supermassive black hole affected by galactic dark matter halos
Guo-He Li, Chen-Kai Qiao, Jun Tao
Periodic orbits exhibiting zoom-whirl behavior have become attractive topics for studying particle dynamics and gravitational wave emission in extreme-mass-ratio inspirals (EMRIs).…

Orbital Dynamics and Gravitational Wave Signatures of Extreme Mass Ratio Inspirals in Galactic Dark Matter Halos
Guo-He Li, Chen-Kai Qiao, Jun Tao
In astrophysics, extreme mass ratio inspiral (EMRI) systems, which consist of a central supermassive black hole and a stellar-mass compact object (SCO), are typically embedded in g…
