Astronomers have identified 20 ultraviolet-emitting supernova remnants in the Andromeda galaxy

The positions of the 20 SNRs with detected diffuse ultraviolet emission (pink squares) and 5 SNRs with potential, however confounded, diffuse emission (blue squares), superimposed on the picture of the Andromeda Galaxy in filter F148W.

The study reveals a large tunable drag response between a normal conductor and a superconductor

A large drag impact was detected between the graphene layer and the floor superconductor, which may be attributed to a novel interplay between regular electrons and dynamic fluctuations of superconducting phases mediated by static Coulomb fields. Credit score: Tao et al. The Coulomb draw is a phenomenon affecting two digital circuits, by which the charging … Read more

New analog quantum computers to solve previously unsolvable problems

Micrograph picture of the brand new quantum simulator, which options two converging nano-sized metallic semiconductor elements built-in into an digital circuit. Credit score: College School Dublin Physicists have created a brand new kind of analog quantum pc that may deal with powerful physics issues that even essentially the most highly effective digital supercomputers cannot. New … Read more

Physicists discover a new way to solve the strange mystery of dark energy

Physicists have proposed a brand new clarification for darkish power. It could shed insights into the interdependence between quantum discipline principle and normal relativity principle, as two views of the universe and its components. What’s behind darkish power – and what hyperlinks it to the cosmological fixed launched by Albert Einstein? Two physicists from the … Read more

The universe is a little hotter than it should be. The “dark photons” could be to blame.

Observations point out that the intergalactic fuel in our universe is barely hotter than it needs to be. Just lately, a group of astrophysicists used refined laptop simulations to suggest a radical answer: an unique type of darkish matter often known as “darkish matter”. photons“It may very well be heating up the place. These unusual … Read more

Why more physicists are beginning to think that space and time are “illusions”

Final December, the Nobel Prize in Physics was awarded for the experimental affirmation of a quantum phenomenon recognized for greater than 80 years: entanglement. As conceived by Albert Einstein and his collaborators in 1935, quantum objects will be mysteriously associated even when they’re separated by nice distances. However as weird because the phenomenon sounds, why … Read more
