The Panchromatic Hubble Andromeda Treasury IV. A Probabilistic Approach to Inferring the High Mass Stellar Initial Mass Function and Other Power-law Functions
Daniel R. Weisz, Morgan Fouesneau, David W. Hogg +13
We present a probabilistic approach for inferring the parameters of the present day power-law stellar mass function (MF) of a resolved young star cluster. This technique (a) fully…
The Panchromatic Hubble Andromeda Treasury I: Bright UV Stars in the Bulge of M31
Philip Rosenfield, L. Clifton Johnson, Léo Girardi +20
As part of the Panchromatic Hubble Andromeda Treasury (PHAT) multi-cycle program, we observed a 12' \times 6.5' area of the bulge of M31 with the WFC3/UVIS filters F275W and F336W.…
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…
The Panchromatic Hubble Andromeda Treasury
J. J. Dalcanton, B. F. Williams, D. Lang +30
The Panchromatic Hubble Andromeda Treasury (PHAT) is an on-going HST Multicycle Treasury program to image ~1/3 of M31's star forming disk in 6 filters, from the UV to the NIR. The…
