A collaborative paper (Meyers et al.) reporting on the spectral properties of the highly intermittent pulsar J1107-5907 at radio frequencies has recently been accepted for publication.
The publication presents the analysis of simultaneous radio observations of the pulsar with the Murchison Widefield Array (MWA) and the refurbished Molonglo Synthesis Radio Telescope (UTMOST project). The pulsar was simultaneously detected in its bright state on one occasion. The large difference between the centre frequencies of the instruments (154 and 835 MHz) allowed to estimate the spectral index of the pulsed radio emission in that frequency range in a phase-resolved sense for the main pulse and the precursor. Additionally, we analysed the pulse energy distributions at both frequencies.
Many more details and plots can be found in the manuscript.
