Astronomers have searched for rotating radio Transients using the Pushchino Radio Astronomy Observatory. The detection of two new RRATs was reported in a recently published paper.
There are a subclass of pulsars called RRATs. The first objects of this type were identified in 2006 as being intermittent in nature. The nature of these Transients is not known. It's assumed that they are ordinary pulsars.
Astronomers are interested in detecting new RRATs in order to improve our knowledge about their nature, since only a small number of them have been found.
A team of astronomer led by PRAO's Sergey Tyul'bashev has discovered two new RRATs. The Large Phasedarray at PRAO has a channel width of 78 kHz and a time of 12.5 milliseconds. There were 96 spatial beams that were used to conduct the observations.
The large effective area of the radio telescope makes it possible to find RRATs.
The RRATs were far away from the plane of the galaxy. It was estimated that the distances were between 3,100 and 7,200 light years for J 1550+09 and J 2047+13. The measure was calculated to be 21 and 35 pc/ cm 3.
The study states that J2047+12 was detected seven times in the four year period. Two pulse were detected on one of the days for J2047+12 in a time span of nearly three minutes. The half-widths for J2047+13 were measured to be 18 and 35 milliseconds.
The time before the appearance of the pulse from J2047+12 was about 11 hours, according to the astronomer. The researchers concluded that the existence of RRATs is confirmed.
There is a study that shows the existence of rotating Transients that appear less often than one pulse per 10 hours of observations. The long series of observations and the use of the programs described above make it possible to detect rotating radio Transients.
