Kim 3: an Ultra-faint Star Cluster in the Constellation of Centaurus
Dongwon Kim, Helmut Jerjen, Dougal Mackey +2
We report the discovery of an ultra-faint star cluster in the constellation of Centaurus. This new stellar system, Kim 3, features a half light radius of $r_{h}=2.29^{+1.28}_{-0.52…
New dwarf galaxy candidates in the Centaurus group
Oliver Müller, Helmut Jerjen, Bruno Binggeli
Recent studies of the distribution and kinematics of the Milky Way and Andromeda satellite galaxy systems have confirmed the existence of coplanar, corotating structures of galaxie…
The new Milky Way satellites: alignment with the VPOS and predictions for proper motions and velocity dispersions
Marcel S. Pawlowski, Stacy S. McGaugh, Helmut Jerjen
The evidence that stellar systems surrounding the Milky Way (MW) are distributed in a Vast Polar Structure (VPOS) may be observationally biased by satellites detected in surveys of…
Horologium II: a Second Ultra-faint Milky Way Satellite in the Horologium Constellation
Dongwon Kim, Helmut Jerjen
We report the discovery of a new ultra-faint Milky Way satellite candidate, Horologium II, detected in the Dark Energy Survey Y1A1 public data. Horologium II features a half light…
A Hero's Dark Horse: Discovery of an Ultra-Faint Milky Way Satellite in Pegasus
Dongwon Kim, Helmut Jerjen, Dougal Mackey +2
We report the discovery of an ultra-faint Milky Way satellite galaxy in the constellation of Pegasus. The concentration of stars was detected by applying our overdensity detection…
Stellar Substructures around the Hercules Dwarf Spheroidal Galaxy
T. A. Roderick, H. Jerjen, A. D. Mackey +1
We present deep -band DECam stellar photometry of the Hercules Milky Way satellite galaxy, and its surrounding field, out to a radial distance of 5.4 times the tidal radius. W…
Discovery of a Faint Outer Halo Milky Way Star Cluster in the Southern Sky
Dongwon Kim, Helmut Jerjen, Antonino P. Milone +2
We report the discovery of a new, low luminosity star cluster in the outer halo of the Milky Way. High quality photometry is presented, from which a color-magnitude diagram is…
