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…
Probing the Galactic Bulge with deep Adaptive Optics imaging: the age of NGC 6440
L. Origlia, S. Lena, E. Diolaiti +4
We present first results of a pilot project aimed at exploiting the potentiality of ground based adaptive optics imaging in the near infrared to determine the age of stellar cluste…
Discovery of a young massive stellar cluster near HESS J1813-178
Maria Messineo, Donald F. Figer, Ben Davies +3
We present the serendipitous discovery of a young stellar cluster in the Galactic disk at l=12deg. Using Keck/NIRSPEC, we obtained high- and low-resolution spectroscopy of several…
High resolution infrared spectra of NGC 6440 and NGC 6441: two massive Bulge Globular Clusters
L. Origlia, E. Valenti, R. M. Rich
Using the NIRSPEC spectrograph at Keck II, we have obtained infrared echelle spectra covering the 1.5-1.8 micron range for giant stars in the massive bulge globular clusters NGC644…
