This research investigates whether dark energy, responsible for the universe’s accelerating expansion, evolves over time rather than remaining constant. Using galaxy distributions, supernovae, and cosmic microwave data, new statistical methods suggest evolving models may better fit observations, potentially reshaping our understanding of cosmology and the universe’s long-term fate.

This research develops the Remnant Emission Survey Tool (REST) to identify dormant comets—objects that resemble asteroids but may contain ancient solar system chemistry. By analyzing archived images of 3,800 asteroid candidates for faint gas emissions, REST aims to improve classification and deepen understanding of planetary formation and solar system history.

Only five percent of the universe is visible through light, leaving most of it unexplained. Gravitational waves provide a new way to explore this hidden cosmos. By detecting these signals early, researchers can predict cosmic collisions and coordinate telescopes in advance, enabling simultaneous observations that deepen our understanding of the universe.
