"The Crab supernova has been suggested as an electron-capture supernova, but since it happened a thousand years ago, there is not much data on the progenitor star and the explosion itself," lead ...

But the fastest “cameras” in the world – transmission electron microscopes – can capture events on the ... graphene. A diagram of the attomicroscope. The UV laser (pink) sets off an ...

Known an electron-capture supernova, the newly-dubbed type was predicted nearly 40 years ago by astronomer Ken'ichi Nomoto, but only recently observed. Intriguingly, the third type of supernovae ...

[Related: Astronomers may have found the surprisingly elusive medium-sized black hole] Astronomer Ken’ichi Nomoto of the University of Tokyo predicted the third type, the electron-capture ...

A worldwide team led by UC Santa Barbara scientists at Las Cumbres Observatory has discovered the first convincing evidence for a new type of stellar explosion—an electron-capture supernova.

The generation of isolated attosecond pulses in 2001 allowed the fastest of all motions outside the nucleus — electron dynamics in atomic systems — to be captured. Attosecond metrology has ...

Evidence of a new electron-capture supernova supports a 40-year-old astronomical theory and could also shed light on 1,000-year-old records from Japan and China. While there are two primary forms ...

Up to this point, electron acceleration processes have been measured through multiple experimental runs, called a multi-shot mode, but those methods rely on the stability and reproducibility of ...

Physicists have been given the first glimpse of nuclear excitation by electron capture (NEEC), confirming theoretical predictions that were made more than 40 years ago. The global team – led by Jeff ...

These microscopes use a beam of electrons to illuminate extremely small structures, but they can't properly capture something while it's moving. With a laser-assisted electron microscope ...

In the 1970s, a team at Bell Laboratories created an electron crystal by spraying the particles on helium, and they observed the electrons behaving like a crystal. But that experiment was stuck in ...
