Modeling Radio Pulsar Nulling Fractions

The NF is different for different pulsars. Recent studies demonstrate a decreasing number of pulsars with increasing NF, similarly to an exponential decay in the plot for the distribution of NF. This indicates certain underlying patterns...A detectable emission feature found in more than 200 pulsars manifests as a sudden cessation of the entire radio pulsed emission for duration of several pulsar rotations to minutes. Termed “pulse nulling”, the occurrence of the phenome...

New Study Suggests Pulsing Ultraluminous X-ray Sources Are Unlikely Origins of Periodically Active Fast Radio Bursts

A team conducted deep radio observations of eight pulsing ultraluminous X-ray sources (PULXs) using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China and the Parkes radio telescope (Murriyang) in Australia, search...In the vast cosmos, fast radio bursts (FRBs) remain one of the most mysterious astrophysical phenomena ever discovered. These intense, millisecond-duration radio pulses can release in the radio band alone as much energy as the Sun emits ...
