Deep optical imaging of the dark galaxy candidate AGESVC1 282

Michal Bílek, Oliver Müller, Ana Vudragović +1

The blind HI survey Arecibo Galaxy Environment Survey (AGES) detected several unresolved sources in the Virgo cluster, which do not have optical counterparts in the Sloan Digital S…

The abundance of dwarf galaxies around low-mass giants in the Local Volume

Oliver Müller, Helmut Jerjen

The abundance of satellite dwarf galaxies has long been considered a crucial test for the current model of cosmology leading to the well-known missing satellite problem. Recent adv…

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…
