We are able to determine model-dependent $3 \sigma$ upper limits on the parallel component of the mean magnetic field strength of filaments in the intergalactic medium of $\sim 30 \ \mathrm{nG}$ for coherence scales between $1$ and $2. 5 \ \mathrm{Mpc}$, corresponding to a mean upper bound RM enhancement of $\sim 3. 8 \ \mathrm{rad/m^{2}}$ due to filaments along all probed sight-lines.

Using the Murchison Widefield Array (MWA), the low-frequency Square Kilometre Array (SKA1 LOW) precursor located in Western Australia, we have completed the GaLactic and Extragalactic All-sky MWA (GLEAM) survey, and present the resulting extragalactic catalogue, utilising the first year of observations.
