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.
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.
