Researchers simulate the RRAT radio-off fraction

There are objects in the Galaxy that emit single and isolated radio pulses. They are not radio pulsars, because their pulses are not regular and it could take seconds to hours until another pulse can be detected.There are objects in the Galaxy that emit single and isolated radio pulses.

Improving timing precision of millisecond pulsars using polarization

Used data obtained from the Five-hundred-meter Aperture Spherical Radio Telescope ( FAST ) to carry out a study of white noise in MSPs . The study was published in The Astrophysical Journal . The researchers presented measurements of the...Pulsar timing enables the most stringent tests of fundamental physics. By monitoring the pulse times of arrival (ToAs) of an ensemble of stable millisecond pulsars (MSPs), known as a pulsar timing array (PTA), it is possible to detect na...
