Sentences with phrase «as galactic winds»

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.

These outflows are driven by the life and death of stars, specifically stellar winds and supernova explosions, which collectively give rise to a phenomenon known as «galactic wind.»

New stars are springing into life within the bright, colorful «head» of NGC 4861 and ejecting streams of high - speed particles as they do so, which flood outwards to join the wider galactic wind.

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.

The team determined that galactic winds alone could not replenish the newly revealed gaseous reservoirs and suggests that the mass is provided by galactic mergers or accretion from hidden streams of gas, as predicted by current theory.

Sun, clouds, oceans, biology, wind, snow, ice and land interacting as tremendous energies cascade through powerful mechanisms... along with cosmic influences, like cosmic rays that shower the Earth like a galactic gravestone falling on your toe.

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»).

During periods of low activity, the solar wind is unable to repel as many galactic cosmic rays from the Earth's atmosphere.

And noting «zonal mean - winds constitute an important element of global atmospheric circulation,» they go on to suggest,» if the solar cycle can influence zonal mean - winds, then it may affect other features of global climate as well, including oscillations such as the NAO and MJO, of which zonal winds are an ingredient» Thus, «the cause of this forcing» as they describe it, «likely involves some combination of solar wind, galactic cosmic rays, ionosphere - Earth currents and cloud microphysics.»
