“The lantern of the universe” can help us learn more about the fate of the universe


The new study provides a deeper insight into the galaxy of radiation, for several ongoing and upcoming investigations to help us learn more about the composition and destiny of the universe.

The determination of the nature of dark matter and dark energy has led scientists to adopt new tracers of the universe’s large scale structures, such as radio-ray galaxies. These galaxies present a strong radiation line of gases heated by newly formed stars.

The study’s lead author, from the institute of the university of Portsmouth cosmology and gravity Violeta Dr Gonzalez – Perez said: “the galaxy is the lantern of the universe, they showed a short history of the universe that tells us time and space structure changes of the universe in the galaxy star strong form in the spectral characteristics of left a mark, can accurately determine their distance.

Also, since young stars are very bright, can be seen in the time of the universe has strong star-forming galaxies, galaxies these two characteristics make shooting line for a long period of time is very good tracer universe.

However, the current radiation-line galaxy sample is small and its features are not very clear. Computational modeling is the only way to try to understand all the processes involved in the formation and evolution of these galaxies.

At the university of Portsmouth, the world’s leading institute of cosmology and gravity (ICG), astronomers by DiRAC to Durham university (distributed using advanced computing) national supercomputing experimental facilities, explores the radiation characteristic of the galaxy.

Computational experiments focused on the age when the universe changed from material to dark energy. They found that most of the radiation-line galaxies live in the center of a gravitational trap, with the masses equal to 11 billion of our sun. The current numerical model of galaxy formation and evolution also shows that the radiation ray galaxy tracks the potential gravitational potential of galaxies in different ways.

They then compared the results with the expected results of the sdss-iv/eBOSS survey and the dark energy spectrometer (DESI). Both surveys were designed to measure the effects of dark energy on the expansion of the universe.
