SUMMARY:Cornell Department of Astronomy & Space Sciences Fall 2026 Colloqu
 ium Series
LOCATION:Space Sciences Building 105
DESCRIPTION:"Dark matter and cosmic flows"\n\nAbstract: Dark matter scaffo
 lds structure in the universe\, providing most of the gravity that dictat
 es the motions of cosmic structures as the universe expands. I will descr
 ibe how the cosmic microwave background (CMB)\, the oldest light in the u
 niverse\, allows us to (a) map out where the total matter in the universe
  is and (b) together with galaxy surveys\, map out 3d bulk velocities in 
 the universe. The Atacama Cosmology Telescope (ACT) in particular has now
  demonstrated how precision measurements of the CMB allow us to transform
  these observables into state-of-the-art constraints on neutrino mass\, w
 ave dark matter and inflationary non-Gaussianity. I will also show new re
 sults from the Simons Observatory\, which is currently mapping the microw
 ave sky at ten times the speed of ACT.\n\nThe Brinson Lecture:\n\nThis Le
 cture is sponsored by the Brinson Foundation which is a privately funded 
 philanthropic organization that provides an opportunity to focus our fami
 ly’s common interests in encouraging personal initiative\, advancing indi
 vidual freedoms and liberties\, and positively contributing to society in
  the areas of education and scientific research. https://brinsonfoundatio
