New dwarf galaxy candidates in the sphere of influence of the Sombrero galaxy

Ethan Crosby, Helmut Jerjen, Oliver Müller +3

We report the discovery of 40 new satellite dwarf galaxy candidates in the sphere of influence of the Sombrero galaxy (M104) the most luminous galaxy in the Local Volume. Using the…

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,…

Is the correlation between the bulge-to-total stellar mass ratio and the number of dwarf galaxies in tension with CDM?

Oliver Müller, Ethan Crosby

Previous results suggest that there exists a correlation between the size of the bulge of a galaxy and the number of its dwarf galaxy satellites. This was found to be inconsistent…

The imprint of galaxy mergers on satellite planes in a cosmological context

Kosuke Jamie Kanehisa, Marcel S. Pawlowski, Oliver Müller

Flattened and kinematically correlated planes of dwarf satellite galaxies have been observed in the Local Volume. The slinging out of satellites during host galaxy mergers has been…

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…

New dwarf galaxy candidates in the sphere of influence of the Local Volume spiral galaxy NGC2683

E. Crosby, H. Jerjen, O. Müller +3

We present initial results of a survey of host galaxies environments in the Local Volume (Mpc) searching for satellite dwarf galaxy candidates using the wide-field…

Is there a dwarf galaxy satellite-of-satellite problem in CDM?

Oliver Müller, Nick Heesters, Helmut Jerjen +2

Dark matter clusters on all scales, therefore it is expected that even substructure should host its own substructure. Using the Extragalactic Distance Database, we searched for dwa…

Classifying the satellite plane membership of Centaurus A's dwarf galaxies using orbital alignment constraints

Kosuke Jamie Kanehisa, Marcel S. Pawlowski, Oliver Müller +1

The flattened, possibly co-rotating plane of satellite galaxies around Centaurus A, if more than a fortuitous alignment, adds to the pre-existing tension between the well-studied M…
