A spectroscopic study of MATLAS-2019 with MUSE: an ultra-diffuse galaxy with an excess of old globular clusters
Oliver Müller, Francine R. Marleau, Pierre-Alain Duc +10
The MATLAS deep imaging survey has uncovered a plethora of dwarf galaxies in the low density environment it has mapped. A fraction of them are unusually extended and have a low-sur…
The Halos and Environments of Nearby Galaxies (HERON) II: The outer structure of edge-on galaxies
Aleksandr Mosenkov, R. Michael Rich, Andreas Koch +6
The HERON project is aimed at studying halos and low surface brightness details near galaxies. In this second HERON paper we consider in detail deep imaging (down to surface bright…
Metal-poor nuclear star clusters in two dwarf galaxies near Centaurus A suggesting formation from the in-spiraling of globular clusters
Katja Fahrion, Oliver Müller, Marina Rejkuba +7
Studies of nucleated dwarf galaxies can constrain the scenarios for the formation and evolution of nuclear star clusters (NSC) in low-mass galaxies and give us insights on the orig…
Hunting ghosts: the iconic stellar stream(s) around NG5907 under scrutiny
Oliver Müller, Ana Vudragović, Michal Bílek
Stellar streams are regarded as crucial objects to test galaxy formation models, with their morphology tracing the underlying potentials and their occurrence tracking the assembly…
The dwarf galaxy satellite system of Centaurus A
Oliver Müller, Marina Rejkuba, Marcel S. Pawlowski +4
Dwarf galaxy satellite systems are essential probes to test models of structure formation, making it necessary to establish a census of dwarf galaxies outside of our own Local Grou…
A new formulation of the external field effect in MOND and numerical simulations of ultra-diffuse dwarf galaxies application to NGC 1052-DF2 and NGC 1052-DF4
Hosein Haghi, Pavel Kroupa, Indranil Banik +7
The ultra-diffuse dwarf galaxy NGC 1052-DF2 (DF2) has ten (eleven) measured globular clusters (GCs) with a line-of-sight velocity dispersion of km/s ($σ=10.6…
