The anatomy of a cosmic snake reveals the structure of distant galaxies

Mon, 13 Nov 17 00:14:10 -0800

We have a fair understanding of star formation, from the interstellar matter to the diffuse clouds whose gravitational contraction gives birth to stars. But observations of distant galaxies have questioned this picture, the size and mass of these distant stellar nurseries exceeding that of their local counterparts. Astrophysicists from the universities of Geneva and Zurich have tackled this inconsistency and found the first answers thanks to the observation of the cosmic snake.

Hitomi mission glimpses cosmic 'recipe' for the nearby universe

Mon, 13 Nov 17 00:00:20 -0800

Russian scientists have found flaws in popular theories of gravity

Thu, 26 Oct 17 00:08:00 -0700

Taking black holes (as a real object) as a test material, scientists from the Ural Federal university (UrFU, Yekaterinburg) found out that a popular theory of gravity which had seemed to work perfectly at the cosmological level (a subclass of Horndeski theory) is hardly applicable to the real world. They presented their study in the Classical and Quantum Gravity journal.

New evidence for dark matter makes it even more exotic

Wed, 25 Oct 17 00:12:40 -0700

How a neutron star collision proves Einstein's 100-year-old General Relativity prediction

Thu, 19 Oct 17 00:04:00 -0700

A hundred years ago, Albert Einstein published his General Relativity theory, predicting the existence of gravitational waves or ripples in space-time, due to violent motion of massive objects in the universe. Collision and merger of two neutron stars should produce gravitational waves and gamma rays simultaneously. Until a few weeks ago, that could not be proven scientifically. Then researchers saw the collision of two neutron stars on Aug. 17, 2017, and everything changed.

At tremendous precision, the proton and antiproton still seem identical

Wed, 18 Oct 17 00:11:40 -0700

Using a novel two-particle measurement method, a group of researchers measured the magnetic moment of the antiproton at a precision 350 times higher than any previous measurement. The result, published in Nature, shows that the magnetic moments of the proton and antiproton are tremendously close, meaning that so-called CPT asymmetry -- a key factor in the lack of antimatter -- must be very small if it exists at all.

'We immediately rang our team in Australia and told them to get onto the CSIRO telescope as soon as possible,' she said. Watch the 30-sec video explainer.

Astronomers first to see source of gravitational waves in visible light

Mon, 16 Oct 17 00:02:40 -0700

For the first time, astronomers have observed in visible light a cataclysmic cosmic event that generated gravitational waves detected on Earth. The event was the merger of two neutron stars in a galaxy 130 million light-years away. The merger resulted in a supernova-like explosion, the light of which was first observed by a team of astronomers at the Carnegie Institution for Science's Las Campanas Observatory in northern Chile.

CIFAR fellows part of first gravitational wave detection of colliding neutron stars

Mon, 16 Oct 17 00:03:10 -0700

LIGO confirms 1989 prediction about neutron star mergers producing gamma ray bursts

Mon, 16 Oct 17 00:06:00 -0700

Today's announcement by LIGO confirms a longstanding prediction made almost thirty years ago by a team headed by Prof. Tsvi Piran at the Hebrew University of Jerusalem. Published in Nature in 1989 ('Nucleosynthesis, neutrino bursts and γ-rays from coalescing neutron stars'), the paper suggests that when two neutron stars merge they emit, in addition to gravitational waves, a burst of gamma-rays. They also synthesize and eject to outer space rare heavy elements, and form a black hole in this process.

For the first time gravitational waves of merging neutron stars were detected. This also puts further focus on the future accelerator facility FAIR, as conditions for further research on neutron stars can be simulated there.

Science: Ambassadors from distant galaxies

Fri, 13 Oct 17 00:06:20 -0700

Cosmic rays of very high energy have their origin outside of our own galaxy, the Milky Way. This is suggested by a study of the angles of incidence of more than 30,000 particles at the Pierre Auger Observatory in Argentina, which is now reported in the Science journal. This finding of the KIT-managed largest experiment measuring cosmic rays worldwide is another important step on the way towards answering fundamental questions relating to the origin of the universe.

Scientists discover more about the ingredients for star formation

Mon, 09 Oct 17 00:08:30 -0700

In the local universe close to us about 70 percent of the hydrogen gas is found in individual atoms, while the rest is in molecules. Astronomers had expected that as they looked back in time, younger galaxies would contain more and more molecular hydrogen until it dominated the gas in the galaxy. Instead, they found that atomic hydrogen makes up the majority of gas in younger galaxies too.

Surface helium detonation spells end for white dwarf

Wed, 04 Oct 17 00:07:50 -0700

An international team of researchers has found evidence that the brightest stellar explosions in our Universe could be triggered by helium nuclear detonation near the surface of a white dwarf star. Using Hyper Suprime-Cam mounted on the Subaru Telescope, the team detected a type Ia supernova within a day after the explosion, and explained its behavior through a model calculated using the supercomputer ATERUI. This result was reported in Nature published on Oct. 5.
