New Planck Maps Show Entire Sky in ‘Polarised’ Light from the Early Universe

New maps from ESA’s Planck satellite show the entire sky in the ‘polarised’ light from the early Universe, revealing that the first stars formed approx. 100 million years later than previously thought. They also shed new light onto our own Milky Way, whose dust reveals spectacular views of Galactic magnetic fields. Researchers at the Max Planck Institute for Astrophysics have developed important software components for Planck and were intensively involved in evaluation the scientific interpretation of the mission data.

Astronomers Discover Close Pair of White Dwarf Stars

The team of astronomers, led by Miguel Santander-García (Observatorio Astronómico Nacional, Alcalá de Henares, Spain; Instituto de Ciencia de Materiales de Madrid (CSIC - http://www.icmm.csic.es/), Madrid, Spain), has discovered a close pair of white dwarf stars -- tiny, extremely dense stellar remnants -- that have a total mass of about 1.8 times that of the Sun. This is the most massive such pair yet found [1] and when these two stars merge in the future they will create a runaway thermonuclear explosion leading to a Type Ia supernova [2].

New Second Laws of Thermodynamics Noticeable on Quantum Scales

New research from UCL and the Universities of Gdansk, Singapore, and Delft has uncovered additional second laws of thermodynamics which complement the ordinary second law of thermodynamics, one of the most fundamental laws of nature. These new second laws are generally not noticeable except on very small scales, at which point, they become increasingly important.

Scientists Obtain Direct Proof of Presence of Dark Matter in the Innermost Part of the Milky Way

The ubiquitous presence of dark matter in the universe is today a central tenet in modern cosmology and astrophysics. Its existence in galaxies was robustly established in the 1970s with a variety of techniques, including the measurement of the rotation speed of gas and stars, which provides a way to effectively 'weigh' the host galaxy and determine its total mass. These measurements showed that the visible matter only accounts for a fraction of the total weight, the predominant part is delivered by dark matter.

Tinkering with Ferromagnetic Topological Insulators Spoils Desired Effects

Exotic new materials called “ferromagnetic topological insulators” were supposed to be the next big thing, offering potential breakthroughs in electronics and new insights into the physics of solids – but it hasn’t happened.

Overwhelmingly Response at Southwest Quantum Technologies Group Workshop

The goal of the SWQT is to bring together the quantum expertise in the GW4, as well as industry in the southwest and beyond, that may not normally get a chance to interact, foster collaboration, and ultimately strengthen the quantum community, leading to more resources and opportunities for quantum technology research and innovation in the future.

Future Affects the Past in the Quantum World

We’re so used to murder mysteries that we don’t even notice how mystery authors play with time. Typically the murder occurs well before the midpoint of the book, but there is an information blackout at that point and the reader learns what happened then only on the last page.

Young, Pulsating Stars Discovered in Far Side of the Milky Way

A cluster of young, pulsating stars discovered in the far side of the Milky Way may mark the location of a previously unseen dark-matter dominated dwarf galaxy hidden behind clouds of dust.

Physicists Fabricate Key Components for NOvA Neutrino Experiment

Neutrinos, subatomic remnants of the early universe, are high-energy particles that pass at nearly the speed of light through everything – our planet, our bodies – while rarely interacting with other matter. Most of them were born in the beginning, nearly 14 billion years ago, though more are continually made in the nuclear reactions of stars, in human-built nuclear reactors and in particle accelerators used for experimentation.

Roton Structure can be Created in an Atomic Superfluid of Cesium-133

Scientists discovered in 1937 that liquid helium-4, when chilled to extremely low temperatures, became a superfluid that could leak through glass, overflow its containers, or eternally gush like a fountain.
