This research uses gravitational lensing to investigate dark matter, the invisible substance that makes up roughly 80% of the Universe's matter. By studying distortions in light caused by massive galaxies, it seeks to identify dark matter structures and determine whether dark matter is clumpy, smooth, cold, warm, concentrated, or diffuse.

This research searches for dark matter, which makes up most of the universe’s mass, by detecting ultralight particles using sensitive quantum sensors. By scanning frequencies like a radio and minimizing noise at cryogenic temperatures, the experiment aims to identify faint signals, bringing scientists closer to understanding the fundamental composition of the universe.

Dark matter makes up most of the universe but cannot be directly observed. This research studies how dark matter halos evolve using cosmological simulations and the principle of maximum entropy. Results show halo entropy increases over time, indicating their evolution toward equilibrium follows fundamental thermodynamic principles.

This talk explains how precise timekeeping underpins technologies like GPS and how atomic clocks achieve extreme accuracy using atomic oscillations. The research explores a new “active atomic clock” where atoms generate their own light, enabling even greater precision. Improved clocks could advance navigation, physics research, and our understanding of the universe.
