Science Summary:
The millimeter wavelength sky is critical for understanding cosmological foregrounds in order to remove the galactic signature from the cosmological signature. This is especially important in searching for the gravity wave signatures in the Cosmic Microwave Background (CMB). There are two major goals for the longer term effort in Greenland. One is to study the galactic foregrounds by mapping about 50% of the sky AND to feed these maps and understanding into the deep cosmological maps we will make from Greenland at 30, 40 and eventually at 80 GHz to search for evidence of gravitational waves from the early universe. In order to do the latter (search for gravitational waves) researchers must do the former (characterize the galactic foregrounds) as so poignantly been shown by the recent Planck release. Greenland is one of the best observing sites and allows coverage of the northern hemisphere, which is less contaminated by the galaxy and is complimentary to southern hemisphere measurements at higher frequencies that study dust contaminated frequencies. In the longer term we will want to duplicate the same system we build in Greenland in the Southern hemisphere to get complete sky coverage, possibly in Antarctica. This experiment will consist of a series of replicated telescopes using molds and technology the researchers have recently developed that allows for a staged approach with both short term results and long term observations. This data will be of use to not only the field of cosmology but to those who study galactic processes , high energy cosmic rays, galactic magnetic fields, and even studies of the neutrino mass. This program has broad scientific implications and will place Denmark at the forefront of a critical area of cosmology.

Logistics Summary:
With funding from Denmark’s University of Copenhagen, the project team will study the galactic foregrounds of the Milky Way from a ground-based sensing site at Summit Station. They will use data and understanding from these activities to create deep cosmological maps with which to search for evidence of gravitational waves from the early universe. The team’s primary activities involve deployment and operation of a 2.2m microwave telescope and supporting lab structure to carry out project activities. In 2016, one field team member will make a site visit to Summit in August to help researchers plan for future visits. In 2017, no researchers will travel to Greenland. In 2018 four team members will travel to Greenland in late-June/July for the installation of the telescope and supporting structure. Three team members from UCSB will travel via the Air National Guard to Kangerlussuaq and then on to Summit. One member from the University of Oslo will fly via commercial air to Kangerlussuaq and then via ANG onward to join the team at Summit. Two to four team members will be on-site at Summit Station for the installation from late June to mid-August. The telescope itself will be flown in a container from UCSB via the ANG, the container will return from Greenland via commercial sea vessel.

In 2016, CPS will provide Air National Guard (ANG) coordination for one passenger and cargo, and Summit Station user days. NSF will recoup the costs of CPS support directly from the sponsoring institute. The PI will make all other arrangements, including KISS user days, and pay for them through the grant.
