MOIRCS Enables Closer Look at Characteristics of Star-Forming Regions in Ancient Galaxies

Ongoing studies of distant galaxy protoclusters using the Multi-Object Infrared Camera and Spectrograph (MOIRCS) instrument on the Subaru Telescope is giving astronomers a closer look at the characteristics of star-forming regions in galaxies in the early universe. A team of astronomers from the National Astronomical Observatory of Japan (NAOJ) and SOKENDAI (Graduate University of Advanced Studies, Japan) are tracking velocity structures and gaseous metallicities in galaxies in two protoclusters located in the direction of the constellation Serpens. These appear around the radio galaxies PKS 1138-262 (at a redshift of 2.2, Figure 1) and USS 1558-003 (at a redshift of 2.5).

The First Stars Could Have Clustered Together in Phenomenally Bright Groups

The first stars in the Universe were born several hundred million years after the Big Bang, ending a period known as the cosmological ‘dark ages’ – when atoms of hydrogen and helium had formed, but nothing shone in visible light. Now two Canadian researchers have calculated what these objects were like: they find that the first stars could have clustered together in phenomenally bright groups, with periods when they were as luminous as 100 million Suns. Alexander DeSouza and Shantanu Basu, both of the University of Western Ontario in Canada, publish their results in a paper in Monthly Notices of the Royal Astronomical Society.

Breakthrough Results May Guide the Design of New Superconductors

Electric current flows without any resistance in a superconducting state thanks to a surprising redistribution of bonding electrons and the associated electronic and atomic behavior after substitution of some cobalt atoms for iron in barium iron arsenide.

Expansion of Virtual Telescope to Take Detailed Images of Black Holes

Astronomers building an Earth-size virtual telescope capable of photographing the event horizon of the black hole at the center of our Milky Way have extended their instrument to the bottom of the Earth -- the South Pole -- thanks to recent efforts by a team led by Dan Marrone of the University of Arizona.

Peking University Researcher Earns Coveted Award for Research on Superconductivity

On April 1st, 2015, the award ceremony of the Sir Martin Wood China Prize was held on the opening ceremony of the 14th National Seminar of Low Temperature Physics. The inspectors finally decided on two researchers as the prize-winners. They were Li Shiyan from Fudan University and Wang Jian from Peking University. Zhao Zhongxian, an academician of the Chinese Academy of Sciences, hosted the ceremony.

NIST Announces Record Performance of JILA's Strontium Lattice Atomic Clock

In another advance at the far frontiers of timekeeping by National Institute of Standards and Technology (NIST) researchers, the latest modification of a record-setting strontium atomic clock has achieved precision and stability levels that now mean the clock would neither gain nor lose one second in some 15 billion years*—roughly the age of the universe.

Researchers Reveal Molecular Structure of Water's Liquid Surface Using New Quantum Model

The National Physical Laboratory (NPL), the UK's National Measurement Institute in collaboration with IBM and the University of Edinburgh, has used a new quantum model to reveal the molecular structure of water's liquid surface.

Dawn Space Probe Resumes Sending Images of Dwarf Planet Ceres

It was an arrival and a farewell at the same time: On 6 March of this year, when NASA’s Dawn space probe finally arrived at Ceres after a two-and-a-half-year flight through the asteroid belt, the spherical dwarf planet initially disappeared into the darkness. As the space probe was approaching its destination from the dark side, the onboard scientific camera system was unable to take any new pictures. For five long weeks. Now, Ceres has come into view again. Photos from mid-April afford a first glimpse of the north pole of the dwarf planet.

EPS Honors SLAC and Stanford Theoretical Physicist with 2015 High Energy and Particle Physics Prize

James D. Bjorken, a theoretical physicist and professor emeritus at the Department of Energy’s SLAC National Accelerator Laboratory and at Stanford University, has been awarded the 2015 High Energy and Particle Physics Prize of the European Physical Society (EPS). Along with four other scientists, he was honored for theoretical work that revolutionized our understanding of the internal structure of the proton.

Direct Evidence of Pulsing Quasar Could Substantiate Existence of Black Hole Binaries

As two galaxies enter the final stages of merging, scientists have theorized that the galaxies' supermassive black holes will form a "binary," or two black holes in such close orbit they are gravitationally bound to one another. In a new study, astronomers at the University of Maryland present direct evidence of a pulsing quasar, which may substantiate the existence of black hole binaries.

Supermassive Black Hole Exists in Dwarf Starburst Galaxy

Dartmouth astrophysicists and their colleagues have not only proven that a supermassive black hole exists in a place where it isn't supposed to be, but in doing so have opened a new door to what things were like in the early universe.

Asteroid Vesta was well on its Way in Developing into a Planet

Only around 60 million kilometres closer to the Sun than Ceres, another large rock is orbiting in the remote asteroid belt: Vesta. Although its diameter of approximately 530 kilometres makes it a bit too small to be counted as a dwarf planet, it is nevertheless big enough to be the second heaviest and third largest body in this region between the orbits of Mars and Jupiter.

LSST Telescope Construction Begins at Cerro Pachón Site in Chilean Andes

The first stone of the future LSST telescope was laid on 14 April 2015 by the Chilean President Michelle Bachelet, at the Cerro Pachón site in the Chilean Andes. The LSST is the result of a public-private partnership involving several research institutions worldwide, and will be equipped with the most powerful digital camera ever built, partly developed in CNRS laboratories. The 8.4-meter-diameter telescope will shed light on the nature of dark energy, which accelerates the expansion of the Universe.

Possible Explanation for Existence of the Cold Spot in Eridanus Constellation

In 2004, astronomers examining a map of the radiation leftover from the Big Bang (the cosmic microwave background, or CMB) discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected.

First Results from New LBT Exozodi Exoplanet Common Hunt Survey

Astronomers have probed deeper than before into a planetary system 130 light-years from Earth. The observations mark the first results of a new exoplanet survey called LEECH (LBT Exozodi Exoplanet Common Hunt), and are published today in the journal Astronomy and Astrophysics.
