Abstract: The unprecedented low surface brightness sensitivity, high spatial resolution with pristine PSF, and wide-area coverage of Euclid opens up a completely new avenue in the combined investigation of a vast number of low surface brightness dwarf galaxies, their nuclear star clusters as well as their globular cluster systems. In this talk, I will present the results obtained from the study of over a thousand dwarf galaxies detected in the VIS and NISP images of the Early Release Observations (EROs) of the Euclid mission. The properties of the dwarf galaxies, including their type, morphology, color, globular cluster richness and nucleated fraction, will be discussed for the range of distances and environments probed by the EROs. Lastly, I will provide a brief overview of what we have learned from these datasets and how we plan to address the future challenges associated with the expected hundreds-fold increase in dwarf galaxies observed in the Euclid Wide Survey.
