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 investigates “zombie stars” — reanimated white dwarf systems formed through stellar interactions in binary star systems. By analyzing large-scale brightness variations across the Milky Way, the work identified hundreds of these rare objects, providing new insights into stellar evolution, galactic history, and the future lifecycle of stars in our universe.
