Radio signals are the main reason for all communication sources, its important to understand what these signals are and where they come from.
Who discovered radio signals?
Radio waves are generated artificially by transmitters and received by radio receivers, using antennas. Radio waves are very widely used in modern technology for fixed and mobile radio communication.Radio waves were first predicted by mathematical work done in 1867 by Scottish mathematical physicist James Clerk Maxwell.
What is Fast radio Burst?
in 2007 by astronomer Duncan Lorimer discovered A single burst contains as much as energy as 500 million suns—hence, scientists believed earlier that it is like super-massive black holes releasing energy or the glow from a dying star or stars collapsing into each other.
What is FRB?
A fast radio burst (FRB) is a radio pulse of length ranging from a fraction of a millisecond to a few milliseconds, caused by some high-energy astrophysical process.
How radio FRB fast radio burst come in space?
Among the most widely accepted theories on where FRBs originate is that of magnetars or young neutron stars with very powerful magnetic field. It is supposed that magnetar formed through the interactions of two very massive stars orbiting one another in a binary system so compact that it would fit within the orbit of the Earth around the Sun.When the magnetic field of a new-born magnetar changes, it releases energy into the surrounding gas and dust cloud, which in turn absorbs the energy and later releases it into the space.
Another speculation is that the signals, on their way to Earth, pass through a dense magnetic plasma cloud suggesting that they may be close to a massive black hole. A magnetic plasma cloud might be the result of the ejection of a magnetic flux rope from the sun.
How we can detect FRB
To detect an FRB, a telescope has to be pointed directly towards the area in the sky where it originates. However, to pinpoint a burst, scientists need to use several telescopes and compare the signals to determine its exact position.
