The contribution of dissolving star clusters to the population of ultra-faint objects in the outer halo of the Milky Way
Filippo Contenta, Mark Gieles, Eduardo Balbinot +1
In the last decade, several ultra faint objects (UFOs, ) have been discovered in the outer halo of the Milky Way. For some of these objects it is not clear whether…
Exploding Satellites -- The Tidal Debris of the Ultra-Faint Dwarf Galaxy Hercules
Andreas H. W. Küpper, Kathryn V. Johnston, Steffen Mieske +2
The ultra-faint satellite galaxy Hercules has a strongly elongated and irregular morphology with detections of tidal features up to 1.3 deg (3 kpc) from its center. This suggests t…
Dynamical evidence for a strong tidal interaction between the Milky Way and its satellite, Leo V
Michelle L. M. Collins, Erik J. Tollerud, David J. Sand +3
We present a chemodynamical analysis of the Leo~V dwarf galaxy, based on Keck II DEIMOS spectra of 8 member stars. We find a systemic velocity for the system of $\langle v_r\rangle…
At the survey limits: discovery of the Aquarius 2 dwarf galaxy in the VST ATLAS and the SDSS data
G. Torrealba, S. E. Koposov, V. Belokurov +7
We announce the discovery of the Aquarius~2 dwarf galaxy, a new distant satellite of the Milky Way, detected on the fringes of the VST ATLAS and the SDSS surveys. The object was or…
Probing the boundary between star clusters and dwarf galaxies: A MUSE view on the dynamics of Crater/Laevens I
Karina Voggel, Michael Hilker, Holger Baumgardt +5
We present MUSE observations of the debated ultra faint stellar system Crater. We spectroscopically confirm 26 member stars of this system via radial velocity measurements. We deri…
