What can polarized radio emissions reveal about the nature of rotating radio transients? This study investigates the polarized radio emission of RRAT J1854+0306 using single pulses from the Five-hundred-meter Aperture Spherical Telescope (FAST). The research seeks to understand the physical origins of RRATs, which emit sporadic radio bursts. Analyzing the emission characteristics, the study finds that RRAT J1854+0306 exhibits nulls, narrow and weak pulses, and occasional wide and intense bursts with a nulling fraction of 53.2%. Integrated pulse profiles show an ‘S’-shaped position angle curve superposed with orthogonal modes. Individual pulses display diverse morphologies with single, double, or multiple peaks. These nulling behaviors, profile morphology, and polarization properties demonstrate that RRATs share the same physical origins as normal pulsars. The findings support the idea that rotating radio transients are fundamentally related to normal pulsars.
Published in Monthly Notices of the Royal Astronomical Society, this research falls squarely within the journal's scope. The analysis of radio emissions from a rotating radio transient directly addresses topics related to pulsars and astrophysical phenomena, making it highly relevant to the journal's readership.
