Measuring three-nucleon interactions to better understand nuclear data and neutron stars
Though atomic nuclei are often depicted as static clusters of protons and neutrons (nucleons), the particles are actually bustling with movement. Thus, the nucleons carry a range of momenta. Sometimes, these nucleons may even briefly engage through the strong interaction. This interaction between two nucleons can boost the momentum of both and form high-momentum nucleon pairs. This effect yields two-nucleon short-range correlations.
Experiments at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility have studied these pairs to learn how protons and neutrons preferentially pair up at short distances. However, short-range correlations involving three or more nucleons haven’t been detected yet.
Now, in a study published in Physics Letters B, researchers used data from a 2018 experiment in Jefferson Lab’s Hall A to measure the signature of three–nucleon short-range correlations for the first time.
Silicon Valley Startup Claims it Can Turn Mercury Into Gold
San Francisco, California-based Marathon Fusion is proposing a process that uses nuclear fusion to turn mercury into gold — something that has been sought by people for thousands of years.
“Unlike previous attempts, our method is massively scalable, pragmatically achievable, and economically irresistible,” Marathon Fusion said on its website.
The battery-powered Starlink Mini is here
Starlink is a life-changing Internet service that connects people and villages too remote for towers and cables to reach. My own Starlink Mini has been critical in helping me pursue life as a digital nomad from almost anywhere in Europe. And right now, Starlink’s the only game in town for relatively cheap and fast consumer internet that can be quickly deployed into data dead spots.
My overriding thought after using the PeakDo LinkPower for the last few weeks is this: why doesn’t SpaceX make one of these?
Mysterious object found dancing with Neptune
Astronomers have discovered a bizarre object in the outer solar system, 2020 VN40, that dances to Neptune’s gravitational beat in a never-before-seen rhythm. It’s the first of its kind, orbiting the Sun once for every ten orbits of Neptune, and could reshape how we understand the movement and evolution of distant cosmic bodies.
New long-period radio transient discovered
An international team of astronomers reports the discovery of a new long-period radio transient, which received the designation ASKAP J144834−685644 (ASKAP J1448−6856 for short). The newfound transient is a crucial addition to the still short list of sources of this type. The finding was detailed in a paper published July 17 on the arXiv preprint pre-print server.
Long-period radio transients (LPTs) are an emerging class of periodic radio emitters, with ultralong rotation periods (ranging from minutes to hours) and strong magnetic fields. Although some observations have suggested that these transients may originate from rotating neutron stars with extremely strong magnetic fields (magnetars) or magnetic white dwarfs, their true nature still baffles astronomers.
The Australian Square Kilometre Array Pathfinder (ASKAP) is a 36-dish radio-interferometer in Australia, operating at 700 to 1,800 MHz. One of its scientific goals is the characterization of radio transient sky through the detection and monitoring of transient and variable sources.
