Description
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:
Weak gravitational lensing, where the sizes and shapes of background galaxies are slightly distorted by foreground dark matter, is one of the premier tools of precision cosmology. Measuring the small coherent distortion of distant galaxies provides information about the amount of distribution of dark matter in the Universe. Furthermore, the measurement of the time evolution of dark matter structures is a powerful probe of the dark energy. We have several ongoing research projects in the area of weak lensing using both ground- and space-based data. These projects are precursors to ambitious surveys planned for the 2020s, including NASA‘s Nancy Grace Roman Space Telescope, the ESA/NASA Euclid mission, the SuperBIT balloon mission, and the ground-based Vera Rubin Observatory's Legacy Survey of Space and Time (LSST).
The measurement of the clustering and velocities of galaxies in 3 dimensional space, which encompasses Baryon Acoustic Oscillations (BAO) and Redshift Space Distortions (RSD) is another powerful probe of dark matter and dark energy. We also seek to exploit this technique for the missions and surveys mentioned above.
