Positrons from Geminga Now, Hasan Yuksel and Todor Stanev at the University of Delaware and Matthew Kistler at Ohio State University claim that the source of these positrons is Geminga — a nearby and ...

One possibility is that the positrons come from nearby pulsar wind nebulae, which are fast-spinning neutron stars that act as cosmic ray accelerators and produce streams of electrons and positrons.

Researchers at Lawrence Livermore National Laboratory have generated billions of positrons, forming the highest antimatter densities ever created on earth, by using superintense short laser pulses ...

The power of positrons Medical imaging: Positron-emission tomography is more expensive and complex than other body-scanning technologies. But, as this case history explains, it has proven its ...

“It’s no longer simply perturbing the ocean, it’s completely remaking it.” This non-linear plasma environment offers high acceleration gradients and focusing for electrons, but the effect on positrons ...

Extra positrons make for a cosmological mystery More results are released in this week's issue of Nature that find too many … Matt Ford – Apr 1, 2009 9:00 AM | 15 ...

Spinning electrons yield positrons for research Date: June 1, 2016 Source: DOE/Thomas Jefferson National Accelerator Facility Summary: A team of researchers has successfully demonstrated a new ...

To measure the abundance of positrons in cosmic rays, the team used data from the instrument PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics), which launched aboard ...

The positrons were registered by counting the coincidences they produce in two Geiger-Müller counters1. The source from which the positron emission was observed was an aluminium strip 10 thick ...

The video doesn’t shy away from some of the gritty details and describes some of the universe’s anti equivalents, including anti-neutrinos, anti-quarks, and anti-electrons, also known as ...
