Galactic Disk Contoured Into Several Concentric Ripples

The Milky Way galaxy is at least 50 percent larger than is commonly estimated, according to new findings that reveal that the galactic disk is contoured into several concentric ripples. The research, conducted by an international team led by Rensselaer Polytechnic Institute Professor Heidi Jo Newberg, revisits astronomical data from the Sloan Digital Sky Survey which, in 2002, established the presence of a bulging ring of stars beyond the known plane of the Milky Way.

Researchers Spot Black Hole That Grew to Gargantuan Size

A black hole that grew to gargantuan size in the Universe's first billion years is by far the largest yet spotted from such an early date, researchers have announced. The object, discovered by astronomers in 2013, is 12 billion times as massive as the Sun, and six times greater than its largest-known contemporaries. Its existence poses a challenge for theories of the evolution of black holes, stars and galaxies, astronomers say.

Astronomers Identify Nine New Dwarf Satellites Orbiting the Milky Way

A team of astronomers from the University of Cambridge have identified nine new dwarf satellites orbiting the Milky Way, the largest number ever discovered at once. The findings, from newly-released imaging data taken from the Dark Energy Survey, may help unravel the mysteries behind dark matter, the invisible substance holding galaxies together.

New VLA Helps Make "True Color" Radio Image of Fascinating Region with Colliding Galaxies

Researchers using the Karl G. Jansky Very Large Array (VLA) have produced the most detailed image yet of a fascinating region where clusters of hundreds of galaxies are colliding, creating a rich variety of mysterious phenomena visible only to radio telescopes.

Scientists Detect Rotating Dust and Gas Discs Hosting Exceptionally Large and Hot Stars

A team of scientists led by astronomers at the University of Bonn discovered an unusual phenomenon in the centre of the Milky Way: They detected about 20 rotating dust and gas discs in each cluster hosting exceptionally large and hot stars. The existence of these discs in the presence of the destructive UV radiation field of their massive neighbours came as a surprise. The science team is pondering how these rotating discs are able to withstand evaporation under these extreme conditions. The results are published in the most recent edition of the journal Astronomy & Astrophysics.

Gravitational Waves Have Characteristic Spectrum Similar to Spectral Lines of Atoms

It has not yet been possible to measure the gravitational waves predicted by Einstein's theory of general relativity. They are so weak that they get lost in the noise of the measurements. But thanks to the latest simulations of the merging of binary neutron star systems, the structure of the sought-after signals is now known. As a team of German and Japanese theoretical astrophysicists reports in the Editor's choice of the current edition of the scientific journal "Physical Review D", gravitational waves have a characteristic spectrum that is similar to the spectral lines of atoms.

EU Awards €2 Million ERC Consolidator Grant to KIT’s QuantumMagnonics Project

The "QuantumMagnonics" project of Dr. Martin Weides of the Physikalisches Institut of KIT deals with dynamic processes inside ferromagnets, such as iron or cobalt. Results of his fundamental research might be used for magnetic data processing components. The Research Council of the European Union funds the project with EUR 2 million.
