HST absolute Proper Motions of NGC 6681 (M70) and the Sagittarius Dwarf Spheroidal Galaxy
Davide Massari, Andrea Bellini, Francesco R. Ferraro +4
We have measured absolute proper motions for the three populations intercepted in the direction of the Galactic globular cluster NGC 6681: the cluster itself, the Sagittarius dwarf…
Local Group and Star Cluster Dynamics from HSTPROMO (The Hubble Space Telescope Proper Motion Collaboration)
Roeland P. van der Marel, Jay Anderson, Andrea Bellini +17
The Hubble Space Telescope (HST) has proven to be uniquely suited for the measurement of proper motions (PMs) of stars and galaxies in the nearby Universe. Here we summarize the ma…
Optical Proper Motion Measurements of the M87 Jet: New Results from the Hubble Space Telescope
Eileen T. Meyer, W. B. Sparks, J. A. Biretta +5
We report new results from an HST archival program to study proper motions in the optical jet of the nearby radio galaxy M87. Using over 13 years of archival imaging, we reach accu…
A Deep Chandra X-ray Limit on the Putative IMBH in Omega Centauri
Daryl Haggard, Adrienne M. Cool, Craig O. Heinke +4
We report a sensitive X-ray search for the proposed intermediate mass black hole (IMBH) in the massive Galactic cluster, Omega Centauri (NGC 5139). Combining Chandra X-ray Observat…
Third-Epoch Magellanic Cloud Proper Motions II: The Large Magellanic Cloud Rotation Field in Three Dimensions
Roeland P. van der Marel, Nitya Kallivayalil
We present the first detailed assessment of the large-scale rotation of any galaxy based on full three-dimensional velocity measurements. We do this for the LMC by combining our HS…
Hubble Tarantula Treasury Project: Unraveling Tarantula's Web. I. Observational overview and first results
E. Sabbi, J. Anderson, D. J. Lennon +18
The Hubble Tarantula Treasury Project (HTTP) is an ongoing panchromatic imaging survey of stellar populations in the Tarantula Nebula in the Large Magellanic Cloud that reaches int…
