In particular we aim to: 1) Develop semianalytical methods to study NS-NS binaries and spinning isolated NSs, and to constrain the behavior of matter at nuclear density using GW observations; 2) Develop a model-independent framework to study GW signatures of accretion onto massive BHs; 3) Investigate the interplay between BH bomb instabilities and accretion in the context of puzzling phenomena, such as jet emission or gamma-ray bursts; 4) Constrain dark matter candidates by studying their interaction with BHs and NSs in realistic scenarios.
