ALMA Observes Most Distant Oxygen Ever

July 2016, News, , , ,

A team of astronomers has used the Atacama Large Millimeter/submillimeter Array (ALMA) to detect glowing oxygen in a distant galaxy seen just 700 million years after the Big Bang. This is the most distant galaxy in which oxygen has ever been unambiguously detected, and it is most likely being ionised by powerful radiation from young giant stars. This galaxy could be an example of one type of source responsible for cosmic reionisation in the early history of the Universe.

ESO: a view of merging galaxies in distant Universe

By e-EPS. Published on 25 September 2014 in:
News, September 2014, , ,

Using the Atacama Large Millimeter/submillimeter Array [ALMA], and many other telescopes on the ground and in space, an international team of astronomers obtained the best view yet of a collision that took place between two galaxies when the Universe was only half its current age. They enlisted the help of a galaxy-sized magnifying glass to reveal otherwise invisible detail. These new studies of the galaxy H-ATLAS J142935.3-002836 have shown that this complex and distant object looks like the well-known …

E-ELT gets off the ground

By Bénédicte Huchet. Published on 25 August 2014 in:
August 2014, News, , , , ,

On June 2014, an explosion disturbed the silence of the Acatama Desert in Chile. Part of the 3000-metre peak of Cerro Armazones was blasted away in order to prepare a level platform that will host ESO’s European Extremely Large Telescope [E-ELT], the largest optical/infrared telescope in the world.
The Atacama Desert is one of the favourite places for astronomers because of its exceptional conditions: the extremely arid mountain region, that is far away from any source of light pollution, offers a clear sky most of the time. This environment, chosen as the location for the future E-ELT, will also present new…
