DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/5/">Pr
 obing dark matter substructure with astrometric weak lensing</a>\nby Crist
 ina Mondino (Perimeter Institute) as part of NHETC Seminar\n\n\nAbstract\n
 Low-mass structures of dark matter are expected to be entirely devoid of l
 ight-emitting regions and baryons. Precisely because of this lack of baryo
 nic feedback\, small-scale substructures of the Milky Way are a relatively
  pristine testing ground for discovering aspects of dark matter microphysi
 cs and primordial fluctuations on sub-galactic scales. I will present resu
 lts from the first search for galactic dark matter subhalos with time-doma
 in astrometric weak gravitational lensing. The analysis is based on a matc
 hed-filter template of local lensing corrections to the proper motion of s
 tars in the Magellanic Clouds and is most sensitive to compact dark struct
 ures of ten million to a hundred million solar mass.\n
