The WFC3 Galactic Bulge Treasury Program: A First Look at Resolved Stellar Population Tools
Thomas M. Brown, Kailash Sahu, Manuela Zoccali +12
[Abridged] When WFC3 is installed on HST, the community will have powerful new tools for investigating resolved stellar populations. The WFC3 Galactic Bulge Treasury program will o…
Stellar Proper Motions in the Galactic Bulge from deep HST ACS/WFC Photometry
Will Clarkson, Kailash Sahu, Jay Anderson +11
We present stellar proper motions in the Galactic bulge from the Sagittarius Window Eclipsing Extrasolar Search (SWEEPS) project using ACS/WFC on HST. Proper motions are extracted…
The Fundamental Plane of QSOs and the Relationship Between Host and Nucleus
Timothy S. Hamilton, Stefano Casertano, David A. Turnshek
We present results from an archival study of 70 medium-redshift QSOs observed with the Wide Field Planetary Camera 2 on board the Hubble Space Telescope. The QSOs have magnitudes M…
Double-blind test program for astrometric planet detection with Gaia
S. Casertano, M. G. Lattanzi, A. Sozzetti +6
We use detailed simulations of the Gaia observations of synthetic planetary systems and develop and utilize independent software codes in double-blind mode to analyze the data, inc…
