ALMA telescope expose ancient galaxies at record speed


The team of astronomers used the new telescope ALMA (Atacama Large Millimeter / submillimeter Array), to discover the location of more than a hundred galaxies with the most active star formation in the early universe. ALMA telescope is so powerful that just a few hours, he made ​​many observations of distant galaxies, as has been done like all other telescopes around the world for more than a decade.




The most powerful flare zvezdoobrazovatelnoy activity observed in galaxies of the early universe, hidden behind a thick layer of dust that blocks familiar to astronomer’s wavelengths while transmitting submillimeter waves.

The research team used a telescope ALMA, consisting of 66 antennas arranged with a gap between the antennas about 125 meters, to refine the maps of galaxies, compiled by one of the previous generation of telescopes called APEX. In this telescope ALMA took only two minutes for the identification of each individual galaxy, and the sensitivity of the new telescope allowed him to examine the details of the field, 200 times narrower than the blurry spots produced telescope APEX.
