The environment around the black hole can provide us with a promising playground to study the dark matter properties because of the large dark matter density from accretion. I will explore the multi-messenger probes on the dark matter in the vicinity of black holes. More concretely, I will discuss (1) the multi-wavelength signals covering the radio, CMB and gamma rays from the dark matter annihilation/decay (2) the gravitational wave signals from a black hole binary.

biography: Kenji Kadota is a faculty at Hangzhou Institute for Advanced Study, University of Chinese Academy of Sciences. He obtained his PhD degree in 2004 from University of California, Berkeley. He worked as a postdoctoral fellow at Fermilab, Minnesota U., Michigan U., and as a junior faculty at Nagoya U. and a faculty scientist at Institute for Basic Science, before joining HIAS in 2021.  His main research interests focus on particle cosmology, investigating the impact of dark matter on the cosmological/astrophysical observations.
