Miscellaneous Information

Miscellaneous Information:


Dr. Rothschild is a member of NASA review panel for the US contribution to the Japanese Astro-H mission, member of the INTEGRAL Users Group, member of the instrument working group and science associate for the International X-ray Observatory, member of review team for future NASA missions, and occasional member of observing proposal review teams for NASA.

Research Interests

High energy astrophysics, including but not limited to accreting X-ray pulsars, active galactic nuclei, high energy emission from clusters of galaxies; nuclear astrophysics, including the 511 keV positron annihilation radiation, and other line radiation (Al-26, Ti-44, etc.); high energy astrophysics instrumentation, including coded mask imaging and hard X-ray imaging telescopes; mission development, such as the MIRAX concept to monitor X-ray temporal variability for the central region of the Galaxy, hard X-ray telescope missions such as Nustar, Astro-H, and the International X-ray Observatory; humanitarian demining; and detection/monitoring of radionuclides at a distance.


Dr. Rothschild is the lead scientist for the High Energy Astrophysics group, which is nearing the end of the Rossi X-ray Timing Explorer (RXTE) mission for which it provided the High Energy X-ray Timing Experiment (HEXTE), and will continue to analyze the data from it for years to come. The group is currently analyzing observations of accreting X-ray pulsars, active galactic nuclei, and cluster of galaxies from data from INTEGRAL, Suzaku, and Swift missions. This includes some multi-wavelength investigations, all of which are aimed at understanding the behavior of matter under extreme conditions (temperature, gravity, magnetic fields, and radiation). They are continuing to promote the US/Brazil MIRAX mission to monitor the transient X-ray phenomena from the central regions of the Galaxy, where the preponderance of stars reside, and collaborate on the High Energy X-ray Imager instrument for the International X-ray Observatory. They are also continuing to develop an X-ray backscatter coded mask imager for humanitarian demining in collaboration with Defence R&D Canada Suffield.
