Nobody has ever detected a graviton. An NYU physicist found a way to hunt for them anyway — by treating million-light-year filaments of cosmic magnetic field as a detector.
The Jellyfish Nebula turns out to have a sibling. A Stanford-led team used 16 years of gamma-ray data to show the two remnants came from a single binary system — a pairing never seen before.
Astronomers have confirmed LHAASO J1912+1014u as a proton PeVatron, the kind of natural accelerator that has been hunted for decades as the source of the galaxy's highest-energy cosmic rays.
Researchers at 25 institutions showed the mysterious 'low-energy enhancement' comes from magnetic transitions inside the nucleus — a result that changes how fast stars are calculated to build heavy elements.
New theory suggests dark matter consists of multiple components that interact differently depending on their cosmic environment.
Researchers suggest a bold new theory to explain why gamma ray signals appear in the Milky Way but not in smaller galaxies, potentially requiring multiple dark matter components.
New theory explains mysterious gamma-ray signals from Milky Way center while accounting for absence of similar signals in dwarf galaxies.
New theory explains why Milky Way shows gamma ray excess while dwarf galaxies remain silent, suggesting complex dark matter interactions.
Scientists propose that dark matter's complexity could explain why gamma ray signals appear in some cosmic locations but not others, challenging single-particle theories.
A new study suggests dark matter could be a mix of multiple particle types that must interact with each other to produce detectable signals, potentially explaining why gamma-ray signals appear only in some cosmic locations.
Researchers suggest multiple dark matter components could explain why gamma-ray signals appear in the Milky Way but not in dwarf galaxies.
