Cluster Ages to Reconstruct the Milky Way Assembly (CARMA) IV. Chrono-dynamics of seven old star clusters in the Large Magellanic Cloud and the peculiar origin of NGC 1841
F. Niederhofer, D. Massari, F. Aguado-Agelet +15
In this study, we report conclusive evidence for an ancient star cluster that has been accreted by the Large Magellanic Cloud (LMC). By leveraging observations from the Hubble Spac…
Tracing stellar rotation in young massive LMC clusters
Sebastian Kamann, Nate Bastian, Florian Niederhofer +8
We present a detailed analysis of stellar rotation along the main sequences of NGC 1866 and NGC 1856, two young (~200-300 Myr) massive clusters in the Large Magellanic Cloud, using…
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…
Hubble Space Telescope proper motions of Large Magellanic Cloud star clusters -- I. Catalogues and results for NGC 1850
F. Niederhofer, A. Bellini, V. Kozhurina-Platais +11
We present proper motion (PM) measurements for a sample of 23 massive star clusters within the Large Magellanic Cloud using multi-epoch data from the Hubble Space Telescope (HST).…
Discovery of astrometric accelerations by dark companions in the globular cluster Centauri
Imants Platais, Johannes Sahlmann, Leo Girardi +6
We present results from the search for astrometric accelerations of stars in Centauri using 13 years of regularly-scheduled {\it Hubble Space Telescope} WFC3/UVIS calibration o…
The James Webb Space Telescope Mission
Jonathan P. Gardner, John C. Mather, Randy Abbott +1004
Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized…
