About

Nigel Atkins is a Senior Engineer in the Radio & Geo-Astronomy Division and is responsible for the running of a millimeter-wave radio telescope here in Cambridge, MA, as well as supporting instrumentation in a molecular physics laboratory. Prior to working in this position, Nigel was part of the engineering team on the Ultraviolet CoronaGraph experiment, which flew on the SOHO observatory that is/was a joint NASA/ESA venture. Before this excursion into the far UV, Nigel was a senior engineer at the James Clerk Maxwell Telescope in Hawaii responsible for the sub-mm wave heterodyne receivers, IF chain, and back-end.

Telescopes and Instruments

The 1.2 Meter Millimeter-Wave Telescope

Molecular clouds are dark, dense nebulas that are both home to and the raw materials for new stars. The 1.2 Meter Millimeter-Wave Telescope (MWT) at the Center for Astrophysics | Harvard & Smithsonian is dedicated to mapping the locations of these clouds in the Milky Way, which reveals details about the structure of our home galaxy and its star-forming capabilities. This instrument and its twin in Chile revealed the existence of two spiral arms in the Milky Way, structures that were previously unknown.

The Submillimeter Array - Maunakea, HI

Located near the summit of Maunakea on the Big Island of Hawaii, the Submillimeter Array (SMA) is one of the flagship observatories of the Center for Astrophysics | Harvard & Smithsonian. The observatory consists of eight radio dishes working together as one telescope, giving astronomers a window on a wide range of astronomical objects and phenomena: planets and comets in our own Solar System; the birth of stars and planets; and the supermassive black holes hidden at the centers of the Milky Way and other galaxies. The SMA is operated jointly by the CfA and the Academia Sinica in Taiwan.

Event Horizon Telescope (EHT)

Black holes are found in the centers of most galaxies, where they can influence star formation and the distribution of atoms in the environment surrounding them. However, direct observation of a black hole is difficult because it is so small relative to their masses. Founded by Shep Doeleman at the Center for Astrophysics | Harvard & Smithsonian, the Event Horizon Telescope (EHT) captured the first image ever taken of a black hole: specifically, the ring of light produced by matter just as it falls into the black hole at the center of the nearby galaxy M87. The EHT is a virtual observatory consisting of telescopes spanning the planet, from Greenland to the South Pole. The international collaboration operating the EHT includes observatories affiliated with the Center for Astrophysics: the CfA’s Submillimeter Array (SMA) and the Greenland Telescope.

The Greenland Telescope

The polar regions are challenging environments for humans, but worthwhile for astronomy with their long nights and often-clear skies. The Greenland Telescope is the latest telescope to be placed in the Arctic, as part of the Event Horizon Telescope (EHT) project to capture the first images of black holes. The telescope operates in the region of the spectrum where infrared and radio light meet, which is ideal for looking into the dense central region of the Milky Way, where our galaxy’s supermassive black hole resides. The Greenland Telescope is jointly operated by the Center for Astrophysics | Harvard & Smithsonian and the Academia Sinica Institute of Astronomy & Astrophysics (ASIAA) of Taiwan.

Solar and Heliospheric Observer (SOHO)

The Sun is the only star we can study in detail, providing us with the opportunity to observe stellar internal structure, magnetic fields, and atmosphere. Solar and Heliospheric Observer (SOHO), a space observatory jointly operated by NASA and the European Space Agency (ESA), has been one of the best sources for that knowledge. Originally designed to operate for two years, SOHO has provided daily data on the Sun for more than twenty years, making it one of the longest running space observatories. During that time, SOHO has monitored the Sun’s atmosphere, surface, and seismology, using a wide range of scientific instruments. Scientists and engineers at the Center for Astrophysics | Harvard & Smithsonian developed the instrument SOHO uses to measure the ultraviolet spectrum of the Sun.
