Euclid: Data Release 1 (DR1) -- Fornax-7, an ultra-faint companion to the Fornax dwarf spheroidal galaxy? A remote star cluster or dwarf satellite of the Fornax dSph
T. Saifollahi, A. Lançon, A. M. N. Ferguson +165
We report the discovery of an ultra-faint stellar system in the vicinity of the Fornax dwarf spheroidal (dSph) galaxy in Euclid DR1. This system, which we designate Fornax-7, is lo…
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…
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…
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…
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…
Euclid: Early Release Observations -- Dwarf galaxies in the Perseus galaxy cluster
F. R. Marleau, J. -C. Cuillandre, M. Cantiello +193
We make use of the unprecedented depth, spatial resolution, and field of view of the Euclid Early Release Observations of the Perseus galaxy cluster to detect and characterise the…
Euclid: Early Release Observations -- Overview of the Perseus cluster and analysis of its luminosity and stellar mass functions
J. -C. Cuillandre, M. Bolzonella, A. Boselli +199
The Euclid ERO programme targeted the Perseus cluster of galaxies, gathering deep data in the central region of the cluster over 0.7 square degree, corresponding to approximately 0…
Euclid: Early Release Observations -- Globular clusters in the Fornax galaxy cluster, from dwarf galaxies to the intracluster field
T. Saifollahi, K. Voggel, A. Lançon +196
We present an analysis of Euclid observations of a 0.5 deg field in the central region of the Fornax galaxy cluster that were acquired during the performance verification phase…
Euclid: Early Release Observations -- Programme overview and pipeline for compact- and diffuse-emission photometry
J. -C. Cuillandre, E. Bertin, M. Bolzonella +260
The Euclid ERO showcase Euclid's capabilities in advance of its main mission, targeting 17 astronomical objects, from galaxy clusters, nearby galaxies, globular clusters, to star-f…
The creation of a massive UCD by tidal threshing from NGC 936
Sanjaya Paudel, Pierre-Alain Duc, Sungsoon Lim +9
We study a compact nucleus embedded in an early-type dwarf galaxy, MATLAS-167, which is in the process of disruption by the tidal force of the neighboring giant S0 galaxy, NGC 936,…
Radial velocities and stellar population properties of 56 MATLAS dwarf galaxies observed with MUSE
Nick Heesters, Oliver Müller, Francine R. Marleau +6
Dwarf galaxies have been extensively studied in the Local Group, in nearby groups, and selected clusters, giving us a robust picture of their global stellar and dynamical propertie…
HI observations of the MATLAS dwarf and ultra-diffuse galaxies
Melina Poulain, Francine R. Marleau, Rebecca Habas +8
The presence of HI gas in galaxies is inextricably linked to their morphology and evolution. This paper aims to understand the HI content of the already identified 2210 dwarfs loca…
Ultra diffuse galaxies in the MATLAS low-to-moderate density fields
Francine R. Marleau, Rebecca Habas, Melina Poulain +10
Recent advances in deep dedicated imaging surveys over the past decade have uncovered a surprisingly large number of extremely faint low surface brightness galaxies with large phys…
Flattened structures of dwarf satellites around massive host galaxies in the MATLAS low-to-moderate density fields
N. Heesters, R. Habas, F. R. Marleau +6
It was first observed in the 1970s that the dwarf galaxies surrounding our Milky Way, so-called satellites, appear to be arranged in a thin, vast plane. Similar discoveries have be…
Structure and morphology of the MATLAS dwarf galaxies and their central nuclei
Melina Poulain, Francine R. Marleau, Rebecca Habas +10

Dwarf galaxies in the MATLAS survey: Hubble Space Telescope observations of the globular cluster system in the ultra-diffuse galaxy MATLAS-2019
Oliver Müller, Patrick R. Durrell, Francine R. Marleau +11
Ultra-diffuse galaxies (UDGs) are very low-surface brightness galaxies with large effective radii. Spectroscopic measurements of a few UDGs have revealed a low dark matter content,…
