Online Meeting Link: https://meeting.tencent.com/dm/ZGVDkboF0pFP Abstract: Dark matter remains a mysterious component in our universe. In order to escape existing constraints, it must be at most weakly interacting, and has an upper bound on its allowed mass if it is a thermal relic. I will present a novel method of constraining the microphysics of dark matter using the observed gravitational wave signal, via the impact on structure formation. I will supplement this with forecasts for constraints from 21cm line intensity mapping, as with the next generation of obsesrvatories, these two signals may put the strongest limits yet on dark matter-neutrino scattering. |
