Extreme Mass Ratio Inspirals (EMRIs) - asymmetric binary systems composed by a stellar mass compact object inspiralling into a massive black hole - are promising candidates for probing new fundamental physics.

It has been believed that supermassive black holes (SMBHs) in the majority of nearby galaxies in the universe are powered by accretion flows. Observational evidence and many numerical simulations show of elliptical galaxies have revealed a surprising fact, in the densest regions of massive elliptical galaxies the hot gas rotates very slowly.
