A new study, led by a theoretical physicist at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.

Multi-messenger astronomy offers new estimates of neutron star size and universe expansion
A combination of astrophysical measurements has allowed researchers to put new constraints on the radius of a typical neutron star and provide a novel calculation of the Hubble constant that indicates the rate at which the universe is expanding.

Scientists reveal reaction mechanism of 11Be nucleus
Scientists from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators have lately made new progress in the study of the reaction mechanism of 11Be nucleus. The study will help understand the effect of exotic structures such as the neutron halo on the reaction characteristics. …
Superfluid used to make sounds that might be heard in neutron star
Nobody will ever hear the sounds produced inside a neutron star, but we have created what might be the next best thing using lithium atoms that behave like a superfluid Source: https://www.newscientist.com/article/2261852-superfluid-used-to-make-sounds-that-might-be-heard-in-neutron-star/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Galaxy’s brightest gamma-ray binary system may be powered by a magnetar
A team of researchers led by members of the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has analyzed previously collected data to infer the true nature of a compact object—found to be a rotating magnetar, a type of neutron star with an extremely strong magnetic field—orbiting within LS 5039, the brightest gamma-ray binary system in the…
Hubble sees the brightest kilonova yet
Observations by the Hubble Space Telescope reveal intense infrared radiation from an unusual kilonova probably created by the collision of neutron stars. Source: https://earthsky.org/space/unusual-kilonova-infrared-light-neutron-stars-grb…
Birth of magnetar seen for the first time
Two neutron stars slammed together far away from Earth, and the Hubble may have spotted a magnetar emerging from the aftermath. Source: https://www.livescience.com/neutron-stars-birth-magnetar.html
Neutron star merger results in magnetar with brightest kilonova ever observed
Long ago and far across the universe, an enormous burst of gamma rays unleashed more energy in a half-second than the sun will produce over its entire 10-billion-year lifetime. Source: https://phys.org/news/2020-11-neutron-star-merger-results-magnetar.html…
What is a supernova?
A supernova is a star’s colossal explosion at the end of its life, potentially outshining its entire galaxy. Read about the causes and types of supernovae here. Source: https://earthsky.org/astronomy-essentials/definition-what-is-a-supernova…
We Finally Know What’s Been Making Fast Radio Bursts
Today, researchers are announcing they’ve solved one of the questions that’s been nagging them over the past decade: what exactly produces the weird phenomena known as fast radio bursts (FRBs)? From a report: As their name implies, FRBs involve a sudden blast of radio-frequency radiation that lasts just a few microseconds. We didn’t even know that FRBs existed until 2007 but…
