A new test to investigate the origin of cosmic structure

Many cosmologists believe that the universe's structure is a result of quantum fluctuations that occurred during early expansion. Confirming this hypothesis, however, has proven highly challenging so far, as it is hard to discern between quantum and classical primordial fluctuations when analyzing existing cosmological data.

New method to measure vibrational frequencies in molecular hydrogen ions

An international research collaboration headed by VU-scientist Jeroen Koelemeij developed a new method to measure vibrational frequencies in the molecular hydrogen ion at four hundred times higher precision than before. The results improve the understanding of the fundamental laws of physics and particles such as the proton—topics which have recently been subject to debate. The outcomes of the study were published in Science last week.

Scientists find new deformation mechanism of bulk metallic glass composites

Bulk metallic glass composites (BMGCs) containing in-situ formed β-Ti dendrites are promising for many applications. However, it remains challenging to effectively tune their microstructures and mechanical properties for application.

Can a quantum strategy help bring down the house?

In some versions of the game blackjack, one way to win against the house is for players at the table to work as a team to keep track of and covertly communicate amongst each other the cards they have been dealt. With that knowledge, they can then estimate the cards still in the deck, and those most likely to be dealt out next, all to help each player decide how to place their bets, and as a team, gain an advantage over the dealer.

Calculating the benefits of exascale and quantum computers

A quintillion calculations a second. That's one with 18 zeros after it. It's the speed at which an exascale supercomputer will process information. The Department of Energy (DOE) is preparing for the first exascale computer to be deployed in 2021. Two more will follow soon after. Yet quantum computers may be able to complete more complex calculations even faster than these up-and-coming exascale computers. But these technologies complement each other much more than they compete.

Astronomy and Space news

Interstellar medium of SDSS J2310+1855 explored with ALMA

Using the ALMA Observatory, an international team of astronomers has conducted an observational campaign of interstellar medium (ISM) in a host galaxy of a high-redshift quasar known as SDSS J231038.88+185519.7 (SDSS J2310+1855 for short). Results of the observations, published July 24 on arXiv.org, could improve the knowledge of the properties and nature of this quasar.

Early Mars was covered in ice sheets, not flowing rivers: study

A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today in Nature Geoscience. The findings effectively throw cold water on the dominant "warm and wet ancient Mars" hypothesis, which postulates that rivers, rainfall and oceans once existed on the red planet.

Unequal neutron-star mergers create unique 'bang' in simulations

When two neutron stars slam together, the result is sometimes a black hole that swallows all but the gravitational evidence of the collision. However, in a series of simulations, an international team of researchers including a Penn State scientist determined that these typically quiet—at least in terms of radiation we can detect on Earth—collisions can sometimes be far noisier.

SpaceX capsule and NASA crew make 1st splashdown in 45 years

Two NASA astronauts returned to Earth on Sunday in a dramatic, retro-style splashdown, their capsule parachuting into the Gulf of Mexico to close out an unprecedented test flight by Elon Musk's SpaceX company.

Machine learning finds a surprising early galaxy

New results achieved by combining big data captured by the Subaru Telescope and the power of machine learning have discovered a galaxy with an extremely low 1.6% oxygen abundance, breaking the previous record of the lowest abundance. The measured oxygen abundance suggests that most of the stars in this galaxy formed very recently.

Differences between discs of active and non-active galaxies detected for the first time

A study led by researchers at the Instituto de Astrofísica de Canarias (IAC) comparing the discs of several pairs of spiral galaxies, active and non-active, concludes that in the active discs, the rotational motion of the stars is of greater importance.

Searching for where very unequal mass black hole binaries come from

The direct detection of gravitational waves from at least eleven sources during the past five years has offered spectacular confirmation of Einstein's model of gravity and space-time, while the modeling of these events has provided information on star formation, gamma-ray bursts,neutron stars, the age of the universe, and even verification of ideas about how very heavy elements are produced. The majority of these gravitational wave events arose from the merger of two black holes of comparable masses in an orbiting pair. Near-equal mass pairs are strongly preferred in models of binary black hole formation, whether they result from the evolution of isolated binary stars or from the dynamical pairing of two black holes. This year, however, the LIGO and Virgo gravitational wave observatories reported the first detection of a very unequal mass pair of black holes, GW190412, whose estimated masses are about 30 and eight solar masses. The question, then, is how were they formed?

Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made with the Atacama Large Millimeter/submillimeter Array (ALMA).

Black hole fails to do its job

Astronomers have discovered what can happen when a giant black hole does not intervene in the life of a galaxy cluster. Using NASA's Chandra X-ray Observatory and other telescopes they have shown that passive black hole behavior may explain a remarkable torrent of star formation occurring in a distant cluster of galaxies.

Natural starshades would help astronomers image exoplanets

In the past few decades, the study of extrasolar planets has grown by leaps and bounds, with the confirmation of over 4000 exoplanets. With so many planets available for study, the focus of exoplanet researchers is shifting from discovery to characterization. In the coming years, new technologies and next-generation telescopes will also enable direct imaging studies, which will vastly improve our understanding of exoplanet atmospheres.

Protection against terrorist attacks with homemade explosives

Terrorist attacks often feature the use of homemade explosives. For the police and security forces to be able to take appropriate precautions and assess the damage after an attack, they need access to the right kind of tools. A research team from the Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, EMI, has now developed a sophisticated risk-analysis system to help prevent such attacks. At the same time, the software-based system assists with the forensic investigation of such incidents. It can therefore support the police to foil attacks with homemade explosives and protect the public at major gatherings and other events.
