Add to Calendar 11/15/2019 12:00 pm 11/15/2019 America/Chicago High Energy Phenomenology Seminar: Rachel Nguyen (UIUC) "Multi-Abra: Detecting Dark Matter In Multiple Detectors" & Nicolas Fernandez (UIUC) "Superradiance inferences from Black Holes spins measured by LIGO and X-ray binaries" DESCRIPTION:

Rachel - Axions are a well-motivated class of dark matter models that can couple weakly to the standard model. If the axion couples to the electomagnetic fields, it produces an effective current when an axion comes in contact with a constant magnetic field. The ABRACADABRA experiment is currently running one experiment exploiting this feature to detect axions; however, with more than one experiment we could also learn about the shape of the dark matter velocity distribution. In this talk, we present the simulated data of an axion detection in two ABRACADABRA detectors and demonstrate how we can use this data to predict variances on dark matter velocity distribution parameters.

 

Nicolas - Black holes are the perfect playground for physics, to search for new ultralight bosons. Bosons can form clouds around rotating black holes if their Compton wavelength is comparable to the black hole size, through a process called superradiance, extracting angular momentum and energy from the black hole and populating an exponentially large number of gravitationally-bound states. Gravitational-wave detectors and X-ray binaries measurements can be used to probe the existence of this boson clouds.
