DESCRIPTION:Speakers: Tongyan Lin (University of California\, San Diego)\n
 \nStellar streams are a promising way to probe the gravitational effects o
 f low-mass dark matter (DM) subhalos. In recent years\, there has been a r
 emarkable explosion in the number of stellar streams detected in the Milky
  Way\, and hundreds more may be discovered with future surveys such as LSS
 T. Studies of DM subhalo impacts on streams have so far focused on a few o
 f the thinnest and brightest streams\, and it is not known how much inform
 ation can be gained from combining known streams. I will discuss our work 
 to assess (i) the minimum subhalo mass detectable in a stream and (ii) the
  number of impacts detected across MW streams. Applying our results to con
 firmed Milky Way streams\, we rank order them by their sensitivity to DM s
 ubhalos.\n\nhttps://indico.phys.hawaii.edu/event/2757/
