The Proper Motion Field Along the Magellanic Bridge: a New Probe of the LMC-SMC Interaction
Paul Zivick, Nitya Kallivayalil, Gurtina Besla +6
We present the first detailed kinematic analysis of the proper motions (PMs) of stars in the Magellanic Bridge, from both the \textit{Gaia} Data Release 2 catalog and from \textit{…
A Detection of Sgr A* in the far infrared
Sebastiano D. von Fellenberg, Stefan Gillessen, Javier Graciá-Carpio +14
We report the first detection of the Galactic Centre massive black hole, Sgr~A*, in the far infrared. Our measurements were obtained with PACS on board the \emph{Herschel} satellit…
A Gaia DR 2 and VLT/FLAMES search for new satellites of the LMC
T. K. Fritz, R. Carrera, G. Battaglia +1
A wealth of tiny galaxies populates the surroundings of the Milky Way. Some of these objects might have their origin as former satellites of the Large Magellanic Cloud. Examples of…
The Missing Satellites of the Magellanic Clouds? Gaia Proper Motions of the Recently Discovered Ultra-Faint Galaxies
Nitya Kallivayalil, Laura Sales, Paul Zivick +7
According to LCDM theory, hierarchical evolution occurs on all mass scales, implying that satellites of the Milky Way should also have companions. The recent discovery of ultra-fai…
Gaia DR2 Proper Motions of Dwarf Galaxies within 420 kpc: Orbits, Milky Way Mass, Tidal Influences, Planar Alignments, and Group Infall
T. K. Fritz, G. Battaglia, M. S. Pawlowski +5
A proper understanding of the Milky Way (MW) dwarf galaxies in a cosmological context requires knowledge of their 3D velocities and orbits. However, proper motion (PM) measurements…
The Proper Motion Field of the Small Magellanic Cloud: Kinematic Evidence for its Tidal Disruption
Paul Zivick, Nitya Kallivayalil, Roeland P. van der Marel +9
We present a new measurement of the systemic proper motion of the Small Magellanic Cloud (SMC), based on an expanded set of 30 fields containing background quasars and spanning a $…
