Euclid. ERO. IC 10 and NGC 6822

We present homogeneous photometry in IE, YE, JE, and HE, and in archival UBVRI data, alongside size measurements and properties derived from the spectral energy distribution fitting code BAGPIPES. Through synthetic cluster injection, we conclude our sample is ~50% complete to M<~10^3^M_{sun}_ for ages <~100Myr, and to M<~2x10^4^M_{sun}_ for ages of ~10Gyr. We find that IC 10 has more young clusters than NGC 6822, and its young clusters extend to higher masses, consistent with its starburst nature.

We find several old massive (>~10^5^M_{sun}_) clusters in both dwarfs, including an exceptional cluster in NGC 6822's outskirts with a mass of 1.3x10^6^M_{sun}_, nearly twice as massive as any other old cluster in either galaxy. In NGC 6822, we also identify a previously undetected, old, and extended cluster (R_h_=12.4+/-0.11pc). Using well-defined criteria, we identify 11 candidate GCs in NGC 6822 and nine in IC 10.

Both galaxies have high specific frequencies (S_N) for their luminosities but remain consistent with the known GC scaling relationships in the low-luminosity regime.
