Polarization Diagnostics for Cool Core Cluster Emission Lines
William B. Sparks, James E. Pringle, Robert F. Carswell +6
The nature of the interaction between low-excitation gas filaments at ~10^4 K, seen in optical line emission, and diffuse X-ray emitting coronal gas at ~10^7 K in the centers of ga…
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…
