The Panchromatic Hubble Andromeda Treasury III. Measuring Ages and Masses of Partially Resolved Stellar Clusters
Lori C. Beerman, L. Clifton Johnson, Morgan Fouesneau +14
The apparent age and mass of a stellar cluster can be strongly affected by stochastic sampling of the stellar initial mass function, when inferred from the integrated color of low…
Hierarchically Clustered Star Formation in the Magellanic Clouds
Dimitrios A. Gouliermis, Stefan Schmeja, Volker Ossenkopf +2
We present a cluster analysis of the bright main-sequence and faint pre--main-sequence stellar populations of a field ~ 90 x 90 pc centered on the HII region NGC 346/N66 in the Sma…
PHAT Stellar Cluster Survey I. Year 1 Catalog and Integrated Photometry
L. Clifton Johnson, Anil C. Seth, Julianne J. Dalcanton +21
The Panchromatic Hubble Andromeda Treasury (PHAT) survey is an on-going Hubble Space Telescope (HST) multi-cycle program to obtain high spatial resolution imaging of one-third of t…
Stellar Clusters in M31 from PHAT: Survey Overview and First Results
L. Clifton Johnson, Anil C. Seth, Julianne J. Dalcanton +9
The Panchromatic Hubble Andromeda Treasury (PHAT) is an on-going Hubble Space Telescope (HST) multi-cycle program that will image one-third of the M31 disk at high resolution, with…
