A team of scientists has confirmed the validity of the current model of the distribution of matter in the universe. This was done with the first-ever identifying the source of a quick Flash (Fast Radio Burst, FRB).The phenomenon of rapid, Flash Outer Space (FRB) has been observed on 18 April 2015 by the Commonwealth Scientific and Industrial Reseearch Organisation (CSIRO), which used the 64-metre Parkes tune your radio telescope in Australia. This observation will trigger an alarm and soon many other observatories including Australian Telescope Compact Array (ATCA), asked their listeners to the likely location of the FRB.
FRB signals is a mysterious, bright flashes which are typically a few milliseconds. The genesis of their occurrence is still unknown, researchers have assembled a complete list of phenomena that can be linked to them. Flashes of the FRB are extremely difficult to detect. Against this phenomenon in this article has been seen previously only sixteen events.
Recording FRB flashes in Australia
In the past months were found FRB flashes even years after their actual occurrence in the course of the ongoing analysis of collected materials. Further observations sites in such a situation the FRB flashes were impossible. In this connection, the researchers from the Swinburne University of Technology in Australia have developed a methodology that allows to carry out observation and detection of signals FRB’s in seconds after their occurrence, while alarm logs to other observatories purposively for searching related phenomena and post effects.
Just when described in this article, Flash uses six 22-meter telescope Observatory on ATCA, so I was able to determine the location of the FRB signal possible. ATCA radio telescope observe interaxial glow after Flash FRB, which continued for six days. Specify the location of the phenomenon is a thousand times more accurate than earlier estimation carried out.
Members of the research team from the National Astronomical Observatory of Japan (NAOJ) at the University of Tokyo and Konan University Konan analized photos of FRB instance optical which were made the day after the incident, the Flash output. Used for this purpose, 8.2 meter Subaru Telescope in Hawaii.
Photos appeared unlikely source phenomenon is an elliptical galaxy from us about 6 billion light years. The distance has been determined by the spectroscopic binary after measuring the redshift. At the same time, same Flash FRB targeted other interesting issues connected with the universe around us.
The delay in the way that his radio signal with Flash FRB, indicates the amount of material, which was on the way. With information about the density of the environment between the Earth and the source of the FRB, the scientists were able to get the information “how heavy the universe”, or at least as normal (visible and foreseeable observed available technology) of matter it contains. In the course of these activities is available in the distribution model used the mass of the universe.
Dark matter dominating our universe
Currently, it is assumed that the universe in 70% consists of dark energy, in 25% of the dark matter, and 5% from ordinary, known to us. The researchers through the observation of the stars, galaxies and ubiquitous hydrogen counted that as of now we are able to confirm the presence of half the normal matter (and thus the 2.5%). The rest remained so far difficult to detect.
Now, however thanks to the observation and verification of the FRB Flash distribution of mass in the universe, scientists have announced that the “missing matter” is present at least in the observed area of linear universe and in this way one Astrophysical phenomenon (FRB) used to explain another, from the area of cosmology.
FRB phenomena nature remains still unknown at this time. Over time, the more accurate data is going to mount, so the answer is going to be getting closer. In the search help new observatories, such as the Thirty Meter Telescope, and maybe even indicate further studies of gravitational waves. One of the hypotheses assumes that the flashes of the FRB may also be sources of this confirmed recently.
