SUMMARY:Hierarchical three-body problem
DESCRIPTION:Abstract : The motion of three bodies can be solved perturbatively when a tightly bound inner binary is orbited by a distant perturber on an elliptic orbit. The exchange of angular momentum between the two orbits gives rise to Kozai-Lidov oscillations of eccentricity and inclination characterizing many different systems in astronomy. In this talk\, I will first review the Newtonian version of the Kozai-Lidov mechanism before introducing the effect of relativistic corrections with applications to gravitational wave astronomy. I will show how one can systematically compute first post-Newtonian terms in the hierarchical three-body problem and discuss their influence on the dynamics of the system. \nFinally\, I will present a new kind of relativistic resonance and its effect on the eccentricity of the inner binary\, which could potentially be measurable in the phase of gravitational waves.

SUMMARY:Warm dark matter constraints using indirect searches
DESCRIPTION:Warm dark matter (WDM) could explain some small-scale structure observations that have challenged the cold dark matter (CDM) model\, as warm particles suppress structure formation due to free streaming effects. Observing small-scale structure thus provides a valuable way to distinguish between CDM and WDM. In this talk\, I will present a semi-analytical model for the dark matter substructure evolution. Satellite galaxies form within dark matter subhaloes\, and I will discuss constraints on WDM models based on the observed number of satellites in the Milky Way. Moreover\, warm particles such as sterile neutrinos and axion-like particles can decay into photons\, which are consequently detectable by X-ray telescopes. eROSITA will perform an all-sky X-ray survey\, of which I will present its sensitivity to identify dark matter decay with narrow X-ray line emission.
