About

Szentgyorgyi has worked in a number of astrophysical areas including neutrino astronomy, very high energy gamma astronomy and X-ray astronomy. For the last 25 years he has focused on optical high dispersion stellar spectroscopy with a focus on precision measurement of stellar radial velocities. He has exploited a number of state-of-the-art technologies to improve the precision of these measurements. He is currently the principal investigator of the GMT-Consortium Large Earth Finder (G-CLEF), the first light instrument for the Giant Magellan Telescope. With the G-CLEF scientific team, he is exploring the potential of G-CLEF to detect biomarkers in the atmospheres of habitable-zone exoplanets. In addition to stellar astrophysics, his scientific interests include optics, especially vision and atmospheric phenomena, and musical acoustics.

Telescopes and Instruments

1.5-meter Tillinghast (60-inch) Telescope

The 1.5-Meter (60 Inch) Tillinghast Telescope is a general purpose visible-light telescope located at the Fred Lawrence Whipple Observatory (FLWO) in southern Arizona, operated by the Center for Astrophysics | Harvard & Smithsonian. Astronomers use this telescope to measure the spectrum of light emitted by a wide variety of objects in the Solar System, the Milky Way, and in distant galaxies.

Magellan Telescopes

The twin Magellan Telescopes in Chile are each 6.5 meter optical telescopes. These telescopes are both equipped with instruments to take images and spectra of light from a wide variety of astronomical sources, including exoplanet systems, star-forming regions, supernova remnants, and interacting galaxies. The Magellan Telescopes — named Baade and Clay —  are hosted at the Las Campanas Observatory and are operated by a consortium of institutions, including the Center for Astrophysics | Harvard & Smithsonian, Carnegie Institution for Science, University of Arizona, the University of Michigan, and the Massachusetts Institute of Technology. In addition, CfA scientists and engineers provided a wide field f/5 focal system (including secondary mirror and corrective optics), and a powerful astronomical camera for use at the Clay telescope.

Giant Magellan Telescope

Is Earth unique, or are there other planets with life in the Milky Way? To answer this question and many others, astronomers need larger and more sensitive observatories than anything we currently have. For that reason, the Center for Astrophysics | Harvard & Smithsonian is collaborating with a number of other institutions around the world to create the Giant Magellan Telescope (GMT), currently under construction in Chile. The GMT will consist of seven large mirrors acting in concert as one giant telescope 80 feet across. That large size provides an unprecedented view of the sky and the ability to detect the chemical composition of exoplanet atmospheres. Like NASA’s Hubble Space Telescope, the GMT will be a powerful tool across the field of astronomy, providing insights into the formation of planets, the structure of galaxies, and the evolution of the universe itself.

1.2 Meter (48-inch) Telescope

The 1.2-Meter (48 Inch) Telescope is a general purpose visible-light telescope located at the Fred Lawrence Whipple Observatory (FLWO), a major observational facility of the Center for Astrophysics | Harvard & Smithsonian located in southern Arizona. Astronomers use this telescope to observe objects in the Solar System and the Milky Way, as well as other galaxies, including the supermassive black holes known as quasars. Astronomers also use the 1.2-Meter Telescope to observe star systems that might contain exoplanets, which is a major program for the observatory.

MINiature Exoplanet Radial Velocity Array (MINERVA)

Finding potentially habitable exoplanets is a major goal of modern astronomy, but Earth-like worlds in Earth-like orbits are hard to detect. The MINiature Exoplanet Radial Velocity Array (MINERVA) project is a set of small telescopes designed to look at two related but simpler systems: Earth-size planets close to their host stars, and “super-Earths” in more Earth-like orbits. MINERVA is a collaboration between the Center for Astrophysics | Harvard & Smithsonian, the University of Montana, Penn State, the University of Southern Queensland, and the University of Pennsylvania. The telescopes are hosted at the CfA’s Fred Lawrence Whipple Observatory (FLWO) in Arizona.

MMT Observatory

The MMT Observatory is the premier visible-light and infrared telescope jointly managed by the Smithsonian Astrophysical Observatory, part of the Center for Astrophysics | Harvard & Smithsonian, and the University of Arizona. Located at the Fred Lawrence Whipple Observatory (FLWO) in southern Arizona, this 6.5-meter (21 foot) telescope is used to study objects across the field of astronomy, from the Solar System to distant galaxies. The MMT has provided a testbed for new telescope technologies developed by scientists and engineers at the CfA and the University of Arizona.

Transiting Exoplanet Survey Satellite (TESS)

Astronomers have discovered thousands of planets orbiting other stars. Extrapolating from that knowledge, the Milky Way alone is probably home to hundreds of billions of planets, many of which are likely rocky, Earth-like worlds. NASA’s Transiting Exoplanet Survey Satellite (TESS) is a space observatory designed to look for exoplanets in orbit around 200,000 nearby bright stars, with a particular interest in identifying small planets. Astronomers from the Center for Astrophysics | Harvard & Smithsonian are part of the scientific team to analyze TESS data, as well as performing follow-up observations. The relative closeness of worlds in the TESS survey will allow astronomers to even study some of their atmospheres, using the future Giant Magellan Telescope (GMT) and other observatories. TESS observational program is complementary to NASA’s long-running Kepler/K2 mission, and could identify as many as 20,000 new exoplanet orbiting a wide variety of star types.
