The US has a three pronged contribution to Euclid.  NASA is providing the near infrared detectors and associated electronics for the NISP instrument, NASA is participating in the Euclid Science Ground Segment (the processing of the Euclid photometric and spectroscopic data) via the Euclid NASA Science Center at IPAC (ENSCI), and a number of US scientists are helping to develop the tools and algorithms that Euclid will use to unlock the mysteries of dark matter and dark energy.  The US science participation in Euclid is primarily through three competitively-selected, NASA funded science investigations. These selected science investigations are: Precision Studies of Galaxy Growth and Cosmology Enabled Through a Physical Model for Nebular Emission (PI R. Chary, Caltech), Looking at Infrared Background Radiation Anisotropies with Euclid (PI A. Kashlinsky, GSFC), and Constraining Dark Energy and Gravity with Euclid (PI J. Rhodes, JPL). In addition, there are several US based scientists who are EC members but are not associated with one of these investigations. 
Euclid-US Science Teams:
  • Precision Studies of Galaxy Growth and Cosmology Enabled Through a Physical Model for Nebular Emission (PI R. Chary, Caltech)

  • The total number of EC members in the US is 86. They are:
