Description
I will explore the "elusive universe," where dark matter, neutrinos, and gravity sculpt our observed nature, leaving many open questions.
Our work focuses on opening up new directions to answer these puzzles. I will present two approaches:
1. Using precision astrometry and space mission data to study general relativity, dark matter, cosmic neutrinos, and fifth forces [1, 2].
2. By deploying quantum sensors on spacecraft, inspired by NASA's Deep
Space Atomic Clocks and the Parker Solar Probe, we explore the gravitational interaction of ultralight dark matter bound to the sun [3].
The projects are in collaboration with NASA, ESA, and NIST. They can be extended to studying interstellar objects, primordial black holes, Planet Nine, and topological defects, and were highlighted by the DOE Office of Science.
