Searching for light dark matter in strong gravity environments

If you have a question about this talk, please contact Chandrima Ganguly .

With no discovery of WIM Ps to date, attention is turning towards lighter mass (sub eV) candidates for dark matter such as axion-like-particles. I will discuss their wave-like behaviour, and highlight the challenges in detecting signatures from such light particles in strong gravity environments. In particular, I will discuss accretion of such dark matter onto black holes, and how it may act as a source of dynamical friction. Such observations may be the only way to confirm the nature of dark matter, in the absence of any couplings to standard model particles.
