Euclid: Disky titans -- surprisingly high star formation efficiency in two brightest group galaxies at $z\sim 0.75$

F. Gentile, E. Daddi, D. Elbaz +165

We present the discovery of two disky titans in the first data release of the Euclid satellite. These sources are massive ($M>10^{11}{M}_{\odot }$) star-forming (SFR $\sim 20M_{\odot }$/…
