An MIT-led team says ultralight dark matter could leave a detectable imprint on gravitational waves when black holes merge inside dense dark matter clouds created by superradiance.

A study led by UC Riverside physicist Hai-Bo Yu proposes that dense clumps of self-interacting dark matter could explain anomalies seen in gravitational lenses, stellar streams, and satellite galaxies.

A large study highlighted by Gizmodo found that observations of the universe’s biggest structures remain consistent with Newtonian and Einsteinian gravity, weakening the case that modified gravity alone explains cosmolog

A new Physical Review Letters study led by UC Riverside physicist Hai-Bo Yu argues that self-interacting dark matter could account for three long-running astrophysical puzzles across very different environments.

A new study in the Journal of Cosmology and Astroparticle Physics argues that the long search for dark matter may need a new framing: the lack of a signal could itself point to a more complex dark sector.

A newly reported galaxy, NGC 1052-DF9, adds to a small but consequential set of systems that appear to exist without dark matter, lending support to the controversial ‘Bullet Dwarf’ collision scenario.

The Super Cryogenic Dark Matter Search experiment at SNOLAB has reached its ultra-cold operating temperature, allowing detectors to begin probing a new region of possible light dark matter signals.

Using European Space Agency Gaia data and a new detection algorithm, astronomers have identified dozens of faint stellar-stream candidates around the Milky Way, sharply expanding the map of ancient gravitational debris.

The 2025 Global Physics Photowalk winners offer a rare public look inside particle physics laboratories, turning detectors, cryostats, and experimental spaces into a visual story about discovery.

Astronomers have discovered CDG-2, one of the most enigmatic galaxies ever observed, located 300 million light-years away in the Perseus cluster. Composed of approximately 99 percent dark matter, this ultra-faint object was detected through an innovative technique that searched for clustered groupings of globular star clusters rather than starlight.
