Raithel, Shannon, Johnston & Kerr (2015) detected sporadic, bright, short-duration radio pulses from PSR J0901-4624. These pulses are emitted simultaneously with persistent, periodic emission that dominates the flux density when averaging over many periods of the pulsar. – The left image shows the integrated profile of PSR J0901-4624: total intensity in black , circular polarization in blue , and linear polarization in red . The top trace shows the position angle of the linear polarization with a trace showing the best fit geometrical model. The right image shows the profile of the very bright pulses. These bright pulses have power-law statistics and show a lack of linear polarization in contrast to the integrated profile. We surmise that this pulsar shows two distinct radio emission modes operating simultaneously in the magnetosphere.
