Diffuse galaxy cluster emission at 168 MHz within the Murchison Widefield Array Epoch of Reionization 0-h field

We detect and characterise extended, diffuse radio emission from galaxy clusters at 168 MHz within the Epoch of Reionization 0-hour field: a $45^\circ \times 45^\circ$ region southern sky centred on R.~A.${}= 0^\circ$, decl.${}=-27^\circ$. 29 sources interest; newly detected halo in Abell 0141; relic 2751; 4 new candidates further candidates; phoenix candidate 2556. Additionally, we find 9 with unclassifiable, steep-spectrum as well double system associated RXC J2351.0-1934. present measured source properties such their integrated flux densities, spectral indices ($\alpha$, where $S_\nu \propto \nu^\alpha$), sizes possible. several to have ultra-steep spectra including 0141, if confirmed, showing $\alpha \leq -2.1 \pm 0.1$ data making it one steepest-spectrum haloes known. Finally, compare our sample previously revisit established scaling relations power ($P_{1.4}$) cluster X-ray luminosity ($L_{\mathrm{X}}$) mass ($M_{500}$). that are consistent $P_{1.4}$-$L_{\mathrm{X}}$ $P_{1.4}$-$M_{500}$ relations, see an increase scatter found increasing size likely caused by inhomogeneous determination $P_{1.4}$ across full sample. show MWA is capable detecting relics most Planck catalogue Sunyaev-Zel'dovich depending exact or properties.
