Gravity Group Lunch Seminar, Steve Choi (Princeton University) "Precision Cosmology with Advanced ACTPol" (102 Jadwin Hall)

Fri, Jan 19, 2018, 12:00 pm
102 Jadwin Hall

The Advanced ACTPol upgrade on the Atacama Cosmology Telescope aims to improve the measurement of the cosmic microwave background anisotropies and polarization, using four new dichroic detector arrays fabricated on 150-mm silicon wafers. In 2016, the Atacama Cosmology Telescope began mapping approximately half the sky with increased sensitivity using these new detector arrays. I will discuss the performance of the Advanced ACTPol upgrade and the improved constraints on cosmology.

Salads, sandwiches, and wraps are catered by D'Angelo Italian Market.
Bottled water will be provided.
