About

I am interested in high energy phenomena associated with the winds of massive stars. To study the winds, high resolution spectroscopy is essential. I use data from the Chandra X-ray Observatory and XMM in my research. As a member of the Chandra X-ray Center, my responsibility is leader of the Data Processing.

Projects

ChaMP (Chandra Multiwavelength Project) and ChaMPlane (Chandra Multiwavelength Plane) Survey

High Energy Astrophysics

NASA’s Chandra X-ray Observatory is a groundbreaking space telescope, with abilities beyond anything that came before it. The Chandra Multiwavelength Project (ChaMP) and Chandra Multiwavelength Plane (ChaMPlane) Survey exploit those abilities to catalog the variety of X-ray sources within archival Chandra data, with follow-up using other telescopes in other parts of the spectrum of light. The surveys identified previously unknown galaxy clusters, quasars, neutron star binary systems, and other significant astronomical sources both in the plane of the Milky Way — ChamPLane — and beyond the galaxy — ChaMP. ChaMP and ChaMPlane are led by astronomers at the Center for Astrophysics | Harvard & Smithsonian, in collaboration with researchers at a number of other institutions in the United States and around the world.

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.

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.
