Emission geometry and jitter noise in millisecond pulsars

In an ideal world, pulses from radio pulsars arrive regularly. However, this is not always the case, and the closest to that is probably the millisecond pulsars (MSPs). As the name suggests, these pulsars have very short rotation periods...In an ideal world, pulses from radio pulsars arrive regularly.

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.
