Supporting Stations: South Pole Station
Research Locations: Dome A / Ridge A
This project is a joint US/Australian venture to build and deploy a fully automated, 0.6-meter terahertz astronomical observatory for remote operation at Ridge A – the highest elevation on the Antarctic Plateau. High Elevation Antarctic Terahertz (HEAT) will observe in the 350 micron (0.8 THz) through 150 micron (2 THz) atmospheric windows, the latter of which is unique to Ridge A. HEAT will initiate a Galactic Plane survey of atomic carbon, ionized carbon and carbon monoxide to explore the Galaxy-wide evolution of gas and stars, the formation and destruction of interstellar clouds and the dynamics of star-forming regions. This will be the largest survey of its kind and will serve as a pathfinder for future astronomical observatories on the Plateau. The telescope will be mounted on top of the Australian University of New South Wales' PLATeau Observatory (PLATO) module that provide housing for the instrument's electronics and diesel engines used to generate electrical power during winter observations. PLATO and the telescope will operate autonomously for over a year at a time, with commands and data being transmitted from and to the home institutions via Iridium satellites daily.
Field Season Overview:
This austral summer researchers will deploy the second generation HEAT telescope and refuel and refurbish the Plateau Observatory (PLATO). The field party of American and Australian grantees will be based at Amundsen-Scott South Pole Station where they will acclimate while assembling and testing the new instrument. A lesser number of team members will travel to Ridge A by Twin Otter for a 2-4 day field deployment intended to maximize the probability of success given the remoteness of the site, attention to safety, and accounting for difficult working conditions at altitude.
