DESCRIPTION:Speakers: Boris Betancourt Kamenetskaia (Institute for Basic S
 cience CTPU-CGA)\nA strongly self-interacting component of asymmetric dark
  matter (DM) particles can form compact dark stars (DSs). These objects ha
 ve a broad spectrum of masses and radii\, with distinct evolution historie
 s from both neutron stars and black holes (BHs). These differences allow a
  population of DSs to contribute significantly to the astrophysical merger
  rate in unique and discernible ways. Specifically\, their merger rate cou
 ld dominate at low redshifts over other sources\, while their mass functio
 n may populate windows outside known astrophysical processes. In this pres
 entation\, I will summarize the structure and formation of DSs within a di
 ssipative model\, and show the enhancement of their merger cross-section d
 ue to tidal deformation effects. From this\, I derive the cosmological DS 
 merger rate and discuss the DM parameter space available for observation. 
 These findings open a new window to probe DM substructure and particle int
 eractions through present and future gravitational wave (GW) observatories
