Ten New Galaxy Clusters Discovered

The universe will look more solid every day. Planets, asteroids, stars and galaxies are found every year in considerable amounts.

Discovery web site today to preach about the discovery of 23 clusters of galaxies or clusters of stars consisting of several galaxies by the Atacama Cosmology Telescope (ACT). Among the 23 clusters of galaxies found in it, 10 of which were new galaxy clusters. The findings will be reported in the Astrophysics Journal, which will be published on 10 November.

Mission discovery of new galaxy clusters was started in 2008. The researchers used the ACT technology that would collect microwaves to be able to image the galaxy clusters that want to be found. They chose the Atacama Desert in Chile as a place of observation for the ACT work is not much disturbed because a lot of water vapor.

"Observations in the Atacama, led by Luman Page of Princeton University is a mission to find the 'shadow' which is intended for scientists as clusters of galaxies," said Felipe Menanteau, researchers from the School of Arts and Science, Rutgers, reveals that the purpose of observation.

The shadow in question is the shadow that tercitra galaxy clusters in the ACT. The shadow is created due to the hot gas in clusters of cosmic background radiation cosmic cause increased energy. As a result of that incident, and clusters of galaxies appear in the form of shadows.

Responding to these results, Priyamvada Natarajan, professor of physics and astronomy involved in the study, said, "The results of this study will build our inventory of parts of the universe's most distant and massive. It will also provide an important challenge to the model of the cosmos are now accepted. I am proud of these findings. "

A number of researchers involved in this observation, in addition to Menanteu and Natarajan, is Jack Hughes of Rutgers and Jorge Gonzalez from the Pontifical Catholic University of Chile (PUC).
