Detecting scalar field with extreme mass ratio inspirals

Nicola Franchini SISSA Scuola Internazionale Superiore di Studi Avanzati
I will present extreme mass ratio inspirals (EMRIs), during which a small body spirals into a supermassive black hole, in gravity theories with additional scalar fields. No-hair theorems and properties of known theories that manage to circumvent them introduce a drastic simplification to the problem: the effects of the scalar on supermassive black holes, if any, are mostly negligible for EMRIs in vast classes of theories.
