New Model to Study Pulsational Dynamics of Molecular Cloud Fluctuations at Star Formation Sites

The birth of stars is an event that eludes intuitive understanding. It is the collapse of dense molecular clouds under their own weight that offers the best sites of star formation. Now, Pralay Kumar Karmakar from the Department of Physics at Tezpur University, Assam province, India, and his colleague have proposed a new model for investigating molecular cloud fluctuations at sites of star formation and thus are able to study their pulsational dynamics, in a paper published in EPJ D.

Largest Known Population of Globular Clusters Uncovered by Hubble

NASA's Hubble Space Telescope has uncovered the largest known population of globular star clusters, an estimated 160,000, swarming like bees inside the crowded core of the giant grouping of galaxies known as Abell 1689.

ESO Telescopes Deliver Clearer View of Central Galactic Bulge

Two groups of astronomers have used data from ESO telescopes to make the best three-dimensional map yet of the central parts of the Milky Way. They have found that the inner regions take on a peanut-like, or X-shaped, appearance from some angles. This odd shape was mapped by using public data from ESO’s VISTA survey telescope along with measurements of the motions of hundreds of very faint stars in the central bulge.

Astronomers Begin Mapping Location of Giant Gas Clouds in the Galaxy

A UNSW-led team of astronomers has begun to map the location of the most massive and mysterious objects in our galaxy – the giant gas clouds where new stars are born.

Flat, Disk Galaxies Grow Out of Irregular Appearances and Take on a Smooth Look

It happens to all kinds of flat, disk galaxies – whether they’re big, little, isolated or crowded in a cluster. They all grow out of their irregular, clumped appearance and their older stars take on the same smooth look, predictably fading from a bright center to a dim edge.

Dilute Magnetic Semiconductor Synthesized on a Single Crystal May be Used to Develop Spintronics

Researchers at North Carolina State University have created a new compound that can be integrated into silicon chips and is a dilute magnetic semiconductor – meaning that it could be used to make “spintronic” devices, which rely on magnetic force to operate, rather than electrical currents.

Quantum Properties Are Lost Even in Completely Isolated Quantum Systems

How does a classical temperature form in the quantum world? An experiment at the Vienna University of Technology has directly observed the emergence and the spreading of a temperature in a quantum system. Remarkably, the quantum properties are lost, even though the quantum system is completely isolated and not connected to the outside world. The experimental results are being published in this week’s issue of “Nature Physics”.

New Study Theorizes Look and Behavior of Astatine

Astatine is among the world’s rarest elements – with a maximum half-life of just eight hours, found in tiny amounts in natural radioactive decay chains, but also produced by bombarding bismuth with energetic atomic particles. The late Dale Corson, Cornell’s eighth president, was one of the discoverers of astatine, synthesizing it for the first time with Kenneth McKenzie and Emilio Segre in 1940.

Finding Cosmic Neutrino Events Using Improved Computer Engineering

Building a neutrino telescope — a unique instrument that detects extremely small, high energy particles — out of 5,000 optical sensors embedded in a cubic kilometer of Antarctic ice, a tremendous engineering feat, was just the first challenge.

Quasar 'Dancing' Behind a Gas Cloud in Milky Way Galaxy

Bonn astronomers discover how the image of a distant quasar splits into multiple images by the effects of a cloud of ionized gas in our own Milky Way Galaxy. Such events were predicted as early as in the 1970s, but the first evidence for one now has come from observations performed with the telescope array VLBA and analysed in the Max Planck Institute for Radio Astronomy.

NASA's Nuclear Spectroscopic Telescope Array Discovers 10 New Supermassive Black Holes

NASA's black-hole-hunter spacecraft, the Nuclear Spectroscopic Telescope Array, or NuSTAR, has "bagged" its first 10 supermassive black holes. The mission, which has a mast the length of a school bus, is the first telescope capable of focusing the highest-energy X-ray light into detailed pictures.

Fermi National Accelerator Laboratory Awards Fellowship to UC Graduate Student

Much like the particles he studies, University of Cincinnati graduate student Fady Bishara is an object in motion. He moved to the U.S. from Egypt at 17 years old, studied engineering in Cleveland and moved to Cincinnati a few years after graduation for a job. While here he decided to move from engineering to study theoretical physics.
