We detect and characterise extended , diffuse radio emission from galaxy clusters at 168 MHz within the Epoch of Reionization 0-hour field ; a 45 \degr \times 45 \degr region of the southern sky centred on R. A . = 0 \degr , decl . = -27 \degr .
We detect 31 diffuse radio sources ; 3 of which are newly detected haloes in Abell 0141 , Abell 2811 , and Abell S1121 ; 2 newly detected relics in Abell 0033 and Abell 2751 ; 5 new halo candidates and a further 5 new relic candidates .
Further , we detect a new phoenix candidate in Abell 2556 as well as 2 candidate dead radio galaxies at the centres of Abell 0122 and Abell S1136 likely associated with the brightest cluster galaxies .
Beyond this we find 2 clusters with unclassifiable , diffuse steep-spectrum emission as well as a candidate double relic system associated with RXC J2351.0-1934 .
We present measured source properties such as their integrated flux densities , spectral indices , and sizes where possible .
We find several of the diffuse sources to be ultra-steep including the halo in Abell 0141 which has \alpha \leq - 2.1 \pm 0.1 making it one of the steepest halos known .
Finally , we compare our sample of haloes with previously detected haloes and revisit established scaling relations of the radio halo power ( P _ { 1.4 } ) with the cluster X-ray luminosity ( L _ { \mathrm { X } } ) and mass ( M _ { 500 } ) .
We find consistent fitting parameters for assumed power law relationships , and find that the P _ { 1.4 } – L _ { \mathrm { X } } has less raw scatter than the corresponding P _ { 1.4 } – M _ { 500 } despite inhomogeneous L _ { \mathrm { X } } measurements .
These scaling relation properties are consistent with a sample of only non-cool core clusters hosting radio haloes .
