Testing the performance of the Milanković telescope

A. Vudragović, M. Bílek, O. Müller +2

We have undertaken a multi-band imaging campaign of several galaxies to study their low surface brightness features such as shells and streams. Using the 1.4-m Milanković telescope…

The coherent motion of Cen A dwarf satellite galaxies remains a challenge for CDM cosmology

Oliver Müller, Marcel S. Pawlowski, Federico Lelli +6

The plane-of-satellites problem is one of the most severe small-scale challenges for the standard CDM cosmological model: several dwarf galaxies around the Milky Way and Androme…

The properties of dwarf spheroidal galaxies in the Cen A group: Stellar populations, internal dynamics, and a heart-shaped Halpha ring

Oliver Müller, Katja Fahrion, Marina Rejkuba +7

Dwarf spheroidal galaxies (dSphs) have been extensively investigated in the Local Group, but their low luminosity and surface brightness make similar work in more distant galaxy gr…

Newly discovered dwarf galaxies in the MATLAS low density fields

Rebecca Habas, Francine R. Marleau, Pierre-Alain Duc +16

We present the photometric properties of 2210 newly identified dwarf galaxy candidates in the MATLAS fields. The Mass Assembly of early Type gaLAxies with their fine Structures (MA…

Hunting for low-surface brightness features in nearby galaxy groups

Oliver Müller

On the scale of dwarf galaxies, several tensions between observations and the theory of structure formation have been identified in the Local Group of galaxies. One of them, the pl…

Tip of the red giant branch distance to the nearby dwarf galaxy [TT2009] 25 in the NGC 891 group

Oliver Müller, Rodrigo Ibata, Marina Rejkuba +1

Dwarf galaxies are key objects for small-scale cosmological tests like the abundance problems or the planes-of-satellites problem. It is therefore a crucial task to get accurate in…
