Professor of Astronomy Director of Undergraduate Studies
Research interests: The study of gamma-ray bursts, optical transients (mainly from the Pan-STARRS project), and magnetic fields in low-mass stars and brown dwarfs. He uses observations across the electromagnetic spectrum, from radio to γ-rays.
Professor of Astronomy Astronomer at the Harvard-Smithsonian Center for Astrophysics
Research Interests: Detection and characterization of extrasolar planets, with the goal of studying inhabited worlds. In pursuit of this goal I also pursue novel ground-based and space-based instrumentation, and studies of stellar astrophysics.
Research Interests: Cosmology and extragalactic astronomy with a mix of theoretical and observational methods; the development of the baryon acoustic oscillation method to measure the cosmic distance scale and study dark energy.
Robert Treat Paine Professor of Practical Astronomy
Research Interests:High Energy Astrophysics: Studies of accretion onto compact objects (black holes, neutron stars and white dwarfs). Development of detectors and telescopes for wide-field imaging surveys of black holes discovered in soft-to-hard X-rays. Time Domain Astrophysics: X-ray/optical/IR studies of Transients and variability of black holes in binaries and galactic nuclei to probe extreme physics phenomena and constrain black hole populations. Days-to-Century optical variability studies of stars and quasars with DASCH and followup spectroscopy to constrain formation and evolution of black holes.
Research Interests: Theoretical studies of dynamical processes in cosmology and galaxy formation/galaxy evolution. Numerical simulations of stellar dynamical and hydrodynamical systems. Investigations of the physics of compact objects, particularly neutron stars and the interplay between thermal and magnetic processes in strongly magnetized neutron stars.
Research interests: Observations of supernovae for themselves and for cosmology using HST, Magellan, MMT, and the Whipple Observatory. Use of rest frame infrared observations for Type Ia supernovae to improve measurements of dark energy properties. Ongoing Hubble Space Telescope study of SN 1987A, the brightest since 1604!
Research Interests: His cosmology research focuses on observations of the cosmic microwave background (CMB) to reveal signatures of the physics that drove the birth of the universe, the creation of its structure, and its present-day expansion. His research over the past two decades has involved the design, deployment, and operation of multiple generations of radio telescopes at the Amundsen-Scott Station at the South Pole.
