Sentences with phrase «galactic wind in»

Furthermore, the team can zoom in on parts of the simulation to study phases and properties of galactic wind in isolation.
Expanding the size of the simulation will allow the team to test an alternate theory for the emergence of galactic wind in disk galaxies like M82.
While NGC 4861 would be a perfect candidate to study such winds, recent studies did not find any galactic winds in it.

Not exact matches

Many other potential applications of this dataset are explored in the series of papers, and they include studying the role of faint galaxies during cosmic reionisation (starting just 380,000 years after the Big Bang), galaxy merger rates when the Universe was young, galactic winds, star formation as well as mapping the motions of stars in the early Universe.
THE discovery of powerful galactic «winds», blowing outwards from distant galaxies, could solve a mystery which has long baffled astronomers: why elements heavier than helium are found in the space between galaxies.
Mike Dopita and his colleagues at the Australian National University in Canberra, working with a team led by Zlatan Tsvetanov of Johns Hopkins University in Baltimore, believe that galactic winds provide the answer.
To better understand how galactic wind affects star formation in galaxies, a two - person team led by the University of California, Santa Cruz, turned to high - performance computing at the Oak Ridge Leadership Computing Facility (OLCF), a US Department of Energy (DOE) Office of Science User Facility located at DOE's Oak Ridge National Laboratory (ORNL).
This star - making frenzy gives rise to galactic wind that pushes out more gas than the system keeps in, leading astronomers to estimate that M82 will run out of fuel in just 8 million years.
Previously, astronomers have used x-ray telescopes to observe strong winds very near the massive black holes at galactic centers (artist's concept, inset) and infrared wavelengths to detect the vast outflows of cool gas (bluish haze in artist's concept, main image) from such galaxies as a whole, but they've never done so in the same galaxy.
«By driving turbulence in the reservoirs, these galactic winds extend the starburst phase instead of quenching it,» says Edith Falgarone at the Paris Observatory.
Once Ulysses was in its scheduled orbit, it began observing the solar wind and magnetic field strength at high solar latitudes, finding that the solar wind from high latitudes was moving at about 750 km / s (slower than expected), and that there were large magnetic waves emerging from high latitudes which scattered galactic cosmic rays.
If Svensmark and other researchers are correct the switch between these states could be due to weakness in the solar wind leading to more galactic cosmic rays entering the atmosphere and increasing the nucleation for cloud droplets (just as in a «cloud chamber»).
We propose that the cycle may be caused by modulation of cosmic ray (CR) flux by the Solar system vertical oscillation (64 My period) in the galaxy, the galactic north - south anisotropy of CR production in the galactic halo / wind / termination shock (due to the galactic motion toward the Virgo cluster), and the shielding by galactic magnetic fields.
Cosmogenic isotopes, which are produced by galactic cosmic rays impacting on meteoroids and whose production rate is modulated by the varying HMF convected outward by the solar wind, may offer an alternative tool for the investigation of the HMF in the past centuries.
It's also changes in the solar wind and interplanetary magnetic field, which cycles along with energy output and shields the earth from galactic cosmic rays.
Solar cycles of magnetic variability result in changes in the luminal spectra of the sun, the properties of the solar wind, and the flux of galactic cosmic rays incident on Earth's atmosphere.
The solar wind, by modulating the galactic cosmic rays which reach the earth, determines both the formation of clouds and the carbon dioxide level in the earth's atmosphere — which has nothing to do with emissions from factories or automobiles.
