This is a canonical problem at the frontier of physics (from gravitational-wave observatories to ultralight dark matter haloscopes) and emerging technologies (from quantum imaging to profiling quantum … Read More

However, despite extensive searches through direct, indirect, and collider probes, no conclusive signal has yet been established. In this … Read More

Join Zoom Meeting: https://lbnl.zoom.us/j/94928022788?pwd=emVQWG1mTnhSbHVqekVuenk0VEVQZz09 Title: Dark matter substructure as a probe of dark matter microphysics Abstract: The nature of dark matter on the scales of galaxies and clusters remains uncertain. Several alternatives to the cold dark matter paradigm remain theoretically motivated such as Ultralight dark matter, warm dark matter, and self-interacting dark matter. In this talk I first review how … Read More
