About

I am the Senior Science Advisor in the Director's Office at the Center for Astrophysics | Harvard and Smithsonian. Prior to working in the Director's Office, I served as the Associate Director for the Solar, Stellar, and Planetary Sciences Division. My research focuses on solar and stellar coronae and shocks from accretion on young stars. I am a member of the AtomDB team, producing high energy spectral models for collisionally ionized plasmas. I am a Co-Investigator on Arcus, a Medium Class Explorer proposal for high resolution X-ray spectroscopy.

Projects

AtomDB

High Energy Astrophysics

In extreme environments, where pressure, temperature, and density are high, atoms change the way they emit and absorb light. Electrons are stripped from nuclei, forming a plasma, and the ions emit X-rays when struck by free electrons. To assist astronomers in identifying atoms under these harsh conditions, the Center for Astrophysics | Harvard & Smithsonian maintains the AtomDB database of X-ray spectra. This catalog provides essential information for studying conditions in many astrophysical environments, including those near black holes, stars, and neutron stars.

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.
