Combining the capabilities of observation Herschel Space Observatory of ESA and ground telescopes Keck, astronomers have described hundreds of galaxies with intense star-forming rate (in English called starburst galaxies) who had not previously been observed, revealing extremely high rates of star formation throughout the history the Universe.
The galaxies with intense star-forming rate give birth every year hundreds of solar masses worth being considered as stars, in short intense events. Comparatively, our galaxy, known as the Milky Way, produces on average the equivalent of a single star similar cypress river plantation to the Sun, per year.
The galaxies with intense star-forming rate produce such an amount of stellar light that should not obscure the Milky hundreds to thousands of times more than that eventually happens, but the vast quantities of natural gas fueling them also contain huge amounts of dust resulting vibes star formation. cypress river plantation
Using the Herschel infrared space observatory of ESA, astronomers measured the temperature and brightness of millions of galaxies containing dust. From these measurements can then be calculated the rate of formation for each star galaxy.
"The galaxies with intense star-forming rate is the brightest galaxies in the Universe and contribute significantly to the cosmic star formation, for this reason cypress river plantation it is important to study them in detail and to understand their properties," says Dr. Caitlin Casey from the University of Hawaii , lead author of the work dealing with the discussion of the results in the journal Astrophysical Journal.
"Some of the galaxies found in this new research have star formation rates equivalent to the birth of several thousand stars of solar mass per year, making it some of the brightest infrared galaxies discovered to date."
To give substance to the observations and to understand how star formation has changed during the history cypress river plantation of 13.7 billion years of the universe, the distances of the galaxies were also necessary.
With the Herschel observatory to mark the way, the team of Dr. Casey used the spectrometers of the twin 10-meter WM Keck telescope located on Mount Mauna Kea in Hawaii, achieving the adoption of redshift for 767 galaxies of all galaxies intense star-forming rate.
The redshift provide astronomers with a measure of the distance traveled by the light from each galaxy in the Universe, which in turn indicates when the cosmic story emitted light from each galaxy.
"The data from the Herschel tells us how intensely and fruitfully these galaxies produce stars' says Seb Oliver from the University of Sussex in England, and Chief Investigator program HerMES Key Programme, under which the data was collected.
"Combining this information with the distances calculated from the data Keck, we can reveal the contribution of galaxies cypress river plantation with intense star-forming rate in the total amount of stars produced throughout the history of the Universe."
How formed such a large number of galaxies with intense star-forming rate during the first billion years of existence cypress river plantation of the Universe is a vital problem for the formation of galaxies and studies of evolution.
Another theory assumes that when the Universe was young, some individual galaxies had more gas available cypress river plantation to replenish, which allow higher rates of star formation without the need for the existence of conflicts.
"Before the study was based on Herschel, the largest such research on distant cypress river plantation galaxies with intense star-forming rate included only 73 galaxies in this survey done in conjunction with Keck data in order to determine the characteristics
