Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

Light curve of the gamma-ray flare (bottom) and collection of quasi-simulated images of the M87 jet (top) at various scales obtained in radio and X-ray during the 2018 campaign. The instrument, the ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

When a distant galaxy briefly outshines everything around it in high-energy light, astronomers usually know which playbook to reach for. Gamma-ray bursts tend to fall into familiar categories, either ...

Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, ...

The study of gamma-ray emission from globular clusters (GCs) and their resident millisecond pulsars (MSPs) presents a compelling window into high-energy astrophysics. GCs are densely populated, ...

For decades, astronomers have been puzzled by a mysterious glow of gamma rays emanating from near the center of the Milky Way. Two theories have emerged: either the light was the result of dark matter ...

Here’s what you’ll learn when you read this story: For nearly a century, scientists have been searching for direct evidence of dark matter—one of the key missing pieces of our theoretical ...

"By reproducing relativistic plasma conditions in the lab, we can measure processes that shape the evolution of cosmic jets and better understand the origin of magnetic fields in intergalactic space." ...
