Researchers from Bielefeld and Hamburg establish partial of a largest radio telescope in a world.
People have always been preoccupied by a universe. The largest digital radio telescope, LOFAR, is now opening adult a window. Stars, planets, and galaxies evacuate radio waves that can be many millions of years old. The signals perceived by any particular hire are processed by a mechanism and fabricated into an picture of a heavens. Researchers during Bielefeld University and Universität Hamburg have set adult a hire together with a Netherlands Institute for Radio Astronomy ASTRON. Yesterday (09.09.2015) a 47th hire of a Low Frequency Array (LOFAR) is being strictly inaugurated in Norderstedt.
‘With LOFAR we wish to demeanour apart behind into a past. For a initial time, we shall be means to observe a arrangement of a oldest stars and galaxies in a universe,’ says Professor Dr. Dominik Schwarz a physicist during Bielefeld University. He and his group have designed a hire in team-work with Professor Dr. Marcus Brüggen and his group during a Hamburg Observatory [Hamburger Sternwarte]. The telescope in Norderstedt is assisting to furnish transparent cinema of galaxies even when they are intensely distant. Some of a goals are to detect a initial stars in a universe, to hunt for gravitational waves, and to magnitude captivating fields in a cosmos.
A sum of 192 receiver assemblies stoical of some-more than 3,000 particular antennas in a margin roughly a distance of a football representation are picking adult a signals from space. Via information cable, these data, along with those from a other 49 LOFAR stations in Europe, are being transmitted to a supercomputer in a Netherlands. This assembles them into an picture of a heavens. The thought is to use a radio telescope to investigate how a star has evolved. To do this, a researchers need a map of a star that is as accurate as possible. ‘Once we know how a star is constructed, it will be easier for us to work out how a early star behaved shortly after a Big Bang when it was still reduction than one second old,’ says Dominik Schwarz.
The LOFAR telescope is stoical of a network of receiver fields that collect adult low-frequency radio waves. The telescope works within a formerly mostly unexplored magnitude operation between roughly 10 and 240 megahertz. This is because it is called LOFAR. The acronym stands for ‘LOw Frequency Array’.
The receiver margin in Norderstedt is a sixth LOFAR hire in Germany and has been using given a open of 2015. By a finish of a year, a general LOFAR telescope stoical of a sum of 50 receiver fields in 6 European countries should be complete. Alongside a stations in Germany, there are 38 in a Netherlands, 3 in Poland, and one any in Great Britain, France, and Sweden. For a whole system, information will be analysed from some-more than 10,000 antennas. LOFAR has been assembled by a Netherlands Institute for Radio Astronomy ASTRON.
