Dr. Mario A. Jimenez-Garate Postdoctoral Associate

MIT Center for Space Reseach Cambridge, Massachusetts, USA

I am an X-ray astrophysicist. I am interested in a mixture of experimental development work (X-ray optics for telescopes), observations with X-ray telescopes (X-ray spectroscopy of compact objects), and theory (numerical modeling of accretion disks around neutron stars and black holes). Here is a quick list of my interests:

• Computer Models of X-ray spectra
• X-ray telescopes and Instrumentation
• The X-ray Spectrum of Black Hole Environment
• Accretion Disks
• Photoionized Plasmas
• X-ray Binary Stars
• Active Galactic Nuclei
