If dark matter forms a \"spike\" due to the growth of the massive black hole, it will induce a gravitational drag on the inspiraling object, changing its orbit and gravitational-wave signal. We show that detection of even a single dark matter spike from the EMRIs will severely constrain several popular dark matter c","authors_text":"Kenny C. Y. Ng, Otto A. Hannuksela, Tjonnie G. F.
