About

I am an astrophysicist working in the High Energy Astrophysics Division of the Smithsonian Astrophysical Observatory since 2000. My interests center around the diffuse interstellar medium (ISM), especially supernova remnants and dust. Supernovae inject energy into the ISM and their shock waves destroy dust. A particular interest of mine is the nature of the Local Interstellar Medium (LISM), the region of the ISM that's closest to us, including the gas and dust that is able to penetrate into the Solar System from the surrounding Local Interstellar Cloud. My work includes numerical hydrodynamics and modeling the dust and gas processes in shocks.

Ph.D. in physics from the University of Wisconsin-Madison

Telescopes and Instruments

Chandra

The Chandra X-ray Observatory is NASA’s flagship X-ray observatory, providing essential data on everything from the environment surrounding newborn stars to the emissions from hot plasma inside galaxy clusters. The Smithsonian Astrophysical Observatory (SAO), as part of the Center for Astrophysics | Harvard & Smithsonian, manages Chandra’s day-to-day operations, providing spacecraft control, observation planning, and data processing for astronomers. Chandra is one of NASA’s orbiting Great Observatories, along with the Hubble.

Lynx X-Ray Observatory

The Lynx X-ray Observatory is a proposed X-ray space telescope, designed to be the next generation following NASA’s Chandra X-ray Observatory and the European Space Agency’s upcoming Athena Telescope. This observatory will be able to take images of a larger area of the sky in X-ray light with better resolution than any existing telescope, allowing astronomers to study the first supermassive black holes, the hot gas surrounding galaxies as they evolve, and radiation from the earliest stars. Researchers from the Center for Astrophysics | Harvard & Smithsonian and other universities are presenting Lynx to NASA for consideration in the 2020 Decadal Survey, with a proposed launch date in the mid-2030s.

Spitzer Space Telescope

Infrared light is the key to studying a wide range of astronomical systems, including newborn stars and planets, dust in distant galaxies, and material swirling around black holes. The Spitzer Space Telescope was NASA’s orbiting infrared observatory, and part of NASA’s Great Observatories program, along with the Chandra X-ray Observatory and the Hubble Space Telescope. Scientists and engineers at the Center for Astrophysics | Harvard & Smithsonian led the design, testing, and construction of the Infrared Array Camera (IRAC). The Spitzer Space Telescope was launched in 2003 and retired in 2020.

Arcus

The most powerful astronomical events are often very bright in X-rays, including supermassive black holes, the hot atmospheres of stars, and the extremely hot plasmas in and around galaxy clusters. Arcus is a proposed NASA space telescope designed to study the X-ray spectrum of a wide range of astronomical phenomena to a level of sensitivity higher than any previous X-ray observatory. Center for Astrophysics | Harvard & Smithsonian scientists are the leaders of the collaboration proposing Arcus. The mission proposal will be due in late 2023 and, if ultimately accepted, Arcus would launch in 2031.

SOFIA (Stratospheric Observatory for Infrared Astronomy)

Earth’s atmosphere protects us from harmful radiation, but it also blocks a lot of light useful for astronomy. For that reason, NASA and the German Aerospace Center (DLR) built the Stratospheric Observatory for Infrared Astronomy (SOFIA) to fly aboard a modified commercial aircraft capable of flying above 99% of the light-blocking atmosphere. SOFIA is a powerful, general-purpose infrared observatory used to study the birth of new stars, planetary nebulas and supernova remnants, the atmospheres of Solar System objects, and many more. The American portion of SOFIA management is handled by the Universities Space Research Association (USRA), a private educational corporation consisting of over 100 institutions, including the Center for Astrophysics | Harvard & Smithsonian.
