HST Proper Motion of Andromeda III: Another Satellite Co-orbiting The M31 Satellite Plane

Dana I. Casetti-Dinescu, Marcel S. Pawlowski, Terrence M. Girard +5

We measure the absolute proper motion of Andromeda III using ACS/WFC and WFPC2 exposures spanning an unprecedented 22-year time baseline. The WFPC2 exposures have been processed us…

HSTPROMO Internal Proper Motion Kinematics of Dwarf Spheroidal Galaxies: I. Velocity Anisotropy and Dark Matter Cusp Slope of Draco

Eduardo Vitral, Roeland P. van der Marel, Sangmo Tony Sohn +8

We analyze four epochs of HST imaging over 18 years for the Draco dwarf spheroidal galaxy. We measure precise proper motions (PMs) for hundreds of stars and combine these with exis…

Lopsided distribution of MATLAS and ELVES dwarf satellite systems around isolated host galaxies

Nick Heesters, Helmut Jerjen, Oliver Müller +2

The properties of satellite dwarf galaxies pose important empirical constraints to verify cosmological models on galaxy scales. Their phase-space correlations, in particular, offer…

A too-many dwarf galaxy satellites problem in the M83 group

Oliver Müller, Marcel S. Pawlowski, Yves Revaz +4

Dwarf galaxies in groups of galaxies provide excellent test cases for models of structure formation. This led to a so-called small-scale crisis, including the famous missing satell…

The phase-space distribution of the M81 satellite system

Oliver Müller, Nick Heesters, Marcel S. Pawlowski +3

The spatial distribution of dwarf galaxies around their host galaxies is a critical test for the standard model of cosmology because it probes the dynamics of dark matter halos and…

Molecular and Ionized Gas in Tidal Dwarf Galaxies: The Spatially Resolved Star-Formation Relation

Navyasree Kovakkuni, Federico Lelli, Pierre-alain Duc +12

Tidal dwarf galaxies (TDGs) are low-mass objects that form within tidal and/or collisional debris ejected from more massive interacting galaxies. We use CO() observations from…
