Dwarf galaxies in the MATLAS survey: Hubble Space Telescope observations of nuclear star clusters

Mélina Poulain, F. Marleau, Pierre–Alain Duc, Rubén Sánchez-Janssen et autres

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 star-forming activity triggered by gas infall. We present the study of NSCs in 41 …

Correction to: Structure and morphology of the MATLAS dwarf galaxies and their central nuclei

Mélina Poulain, F. Marleau, Rebecca Habas, Pierre-Alain Duc et autres

In the published version of this article (2021, MNRAS 506, 5494), an error appears in table 1, where the numerical values of the two surface brightness parameters, |$\mu _{0,g}$| and |$\langle \mu _{e,g} \rangle$|⁠, were reported incorrectly. The corrected version of table …

Low surface brightness structures from annotated deep CFHT images: effects of the host galaxy’s properties and environment

Elisabeth Sola, Pierre–Alain Duc, M Urbano, Felix Richards et autres

ABSTRACT Hierarchical galactic evolution models predict that mergers drive galaxy growth, producing low surface brightness (LSB) tidal features that trace galaxies’ late assembly. These faint structures encode information about past mergers and are sensitive to the properties and environment of the host …

Evidence of star cluster migration and merger in dwarf galaxies

Mélina Poulain, Rory Smith, Pierre–Alain Duc, F. Marleau et autres

Abstract Nuclear star clusters (NSCs) are the densest stellar systems in the Universe. These clusters can be found at the centre of all galaxy types but tend to favour galaxies of intermediate stellar mass around 10 9 M ⊙ (refs. 1,2 ). …

Euclid: Quick Data Release (Q1) -- A census of dwarf galaxies across a range of distances and environments

F. R. Marleau, Rebecca Habas, D. Carollo, C. Tortora et autres

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 interesting fields in which to search for dwarf galaxies in local density environments. We take advantage …

Euclid preparation

Karina Voggel, A. Lançon, T. Saifollahi, S. S. Larsen et autres

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 debate. The compact nature of globular clusters means that they are hard to spatially resolve …

Dwarf galaxies in the MATLAS survey: The satellite system of NGC 474 under scrutiny with MUSE

Oliver Müller, Francine R. Marleau, Nick Heesters, Pierre–Alain Duc et autres

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 planes of dwarf galaxies discovered in the local Universe. If confirmed, this lends credence to …
