SUMMARY:Connecting the dots: from astronomical surveys and experiments
  to fundamental physics of dark universe\, Theory Seminar (High Energy
 /Cosmology)\, Yao-Yuan Mao\, Rutgers
DESCRIPTION:The standard model of cosmology\, despite its success in e
 xplaining most current observations\, consists of several mysterious c
 omponents\, such as dark matter\, dark energy\, and inflation. Current
  and upcoming multiwavelength sky mappers\, gravitational wave observa
 tions\, and particle experiments will provide an unprecedented collect
 ion of complementary datasets\, which have brought\, and will continue
  to bring us novel and exciting discoveries. One of the main challenge
 s in the next decade is to translate these discoveries into solid unde
 rstandings of the fundamental physics of the universe\, especially its
  dark components. We hence need to carefully connect the “dots” be
 tween theories and observations. In this talk\, I will demonstrate the
  pivotal roles of numerical simulations\, empirical models\, and stati
 stical analyses in the said connection. I will illustrate how theoreti
 cal uncertainties impact the interpretation of observations and how we
  mitigate those impacts\, with specific case studies including direct 
 detection experiments\, gravitational lensing\, and dwarf galaxy surve
 ys (as dark matter probes). Finally\, taking the LSST Dark Energy Scie
 nce Collaboration as an example\, I will discuss how we work together 
 as a community to be prepared to answer fundamental questions about th
 e dark universe with upcoming datasets.
