Euclid: Calibrating distances from surface brightness fluctuations with Early Release Observations of the Fornax cluster
R. Habas, M. Cantiello, G. Riccio +169
Surface brightness fluctuations (SBF), the pixel-to-pixel variations in flux that arise from the statistical distribution of stars in galaxy images, provide a powerful tool to meas…
Dwarf galaxies in the MATLAS Survey: Hubble Space Telescope observations of nuclear star clusters
Mélina Poulain, Francine R. Marleau, Pierre-Alain Duc +8
In dwarf galaxies, nuclear star clusters (NSCs) are believed to primarily form from the migration and merger of globular clusters (GCs), with a possible contribution from in-situ s…
Euclid preparation LXXIX. Using mock low surface brightness dwarf galaxies to probe Euclid Wide Survey detection capabilities
Euclid Collaboration, M. Urbano, P. -A. Duc +313
Local Universe dwarf galaxies can serve as both cosmological and mass assembly probes. Deep surveys have enabled the study of these objects down to the low surface brightness (LSB)…

Koshy George, A. Boselli, J. -C. Cuillandre +177
Euclid is delivering optical and near-infrared imaging data over 14,000 deg on the sky at spatial resolution and surface brightness levels that can be used to understand the mo…
Evidence of star cluster migration and merger in dwarf galaxies
Mélina Poulain, Rory Smith, Pierre-Alain Duc +8
Nuclear star clusters (NSCs) are the densest stellar systems in the Universe. They can be found at the center of all galaxy types, but tend to favor galaxies of intermediate stella…
Euclid: Quick Data Release (Q1) -- A census of dwarf galaxies across a range of distances and environments
F. R. Marleau, R. Habas, D. Carollo +204
The Euclid Q1 fields were selected for calibration purposes in cosmology and are therefore relatively devoid of nearby galaxies. However, this is precisely what makes them interest…
Low Surface Brightness structures from annotated deep CFHT images: effects of the host galaxy's properties and environment
Elisabeth Sola, Pierre-Alain Duc, Mathias Urbano +20
Hierarchical galactic evolution models predict that mergers drive galaxy growth, producing low surface brightness (LSB) tidal features that trace galaxies' late assembly. These fai…
Euclid: Early Release Observations -- Interplay between dwarf galaxies and their globular clusters in the Perseus galaxy cluster
T. Saifollahi, A. Lançon, Michele Cantiello +183
We present an analysis of globular clusters (GCs) of dwarf galaxies in the Perseus galaxy cluster to explore the relationship between dwarf galaxy properties and their GCs. Our foc…
Euclid: Early Release Observations of diffuse stellar structures and globular clusters as probes of the mass assembly of galaxies in the Dorado group
M. Urbano, P. -A. Duc, T. Saifollahi +160
Deep surveys reveal tidal debris and associated compact stellar systems. Euclid's unique combination of capabilities (spatial resolution, depth, and wide sky coverage) will make it…
Dwarf Galaxies in the MATLAS Survey: The satellite system of NGC474 under scrutiny with MUSE
Oliver Müller, Francine R. Marleau, Nick Heesters +12
A recent study of the distribution of dwarf galaxies in the MATLAS sample in galaxy groups revealed an excess of flattened satellite structures, reminiscent of the co-rotating plan…
Dwarf Galaxies in the MATLAS Survey: Hubble Space Telescope Observations of the Globular Cluster Systems of 74 Ultra Diffuse Galaxies
Francine R. Marleau, Pierre-Alain Duc, Melina Poulain +7
Ultra diffuse galaxies, characterized by their low surface brightness and large physical size, constitute a subclass of dwarf galaxies that challenge our current understanding of g…

Euclid preparation. LVIII. Detecting globular clusters in the Euclid survey
Euclid Collaboration, K. Voggel, A. Lançon +270
Extragalactic globular clusters (EGCs) are an abundant and powerful tracer of galaxy dynamics and formation, and their own formation and evolution is also a matter of extensive deb…
