About the NASA Postdoctoral Program
The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.
Description:
LISA is a planned joint NASA/ESA mission to measure gravitational waves from space. Astrophysical sources for LISA include: compact binaries (e.g., white dwarf –white dwarf binaries), mergers of supermassive black holes, and inspirals of compact stellar-mass objects into supermassive black holes. Dr. Cutler does research on LISA sources and is developing methods and tools to be used in LISA data analysis. In particular, he is currently doing studies on how accurately physical source parameters (such as the source's location on the sky, or the masses of both objects in a binary) could be extracted from the noisy LISA data set. He is also developing computationally efficient strategies for digging weak signals out of the data, and he is participating in the Mock LISA Data Challenges, wherein synthetic source signals are added, in a blind way, to synthetic LISA noise, and participants are challenged to extract the signals and recover the correct parameter values. The goal of the Mock LISA Data Challenges is to develop the data analysis tools that will be needed for LISA, and to demonstrate readiness in this area.
