The ACS Nearby Galaxy Survey Treasury VIII. The Global Star Formation Histories of 60 Dwarf Galaxies in the Local Volume
Daniel R. Weisz, Julianne J. Dalcanton, Benjamin F. Williams +11
We present uniformly measured star formation histories (SFHs) of 60 nearby (D~4Mpc) dwarf galaxies based on CMDs of resolved stellar populations from images taken with HST as part…
The ACS Nearby Galaxy Survey Treasury
Julianne J. Dalcanton, Benjamin F. Williams, Anil C. Seth +24
The ACS Nearby Galaxy Survey Treasury (ANGST) is a systematic survey to establish a legacy of uniform multi-color photometry of resolved stars for a volume-limited sample of nearby…
Confirmation of Color Dependent Centroid Shift Measured After 1.8 years with HST
Aparna Bhattacharya, David Bennett, Jean Philippe Beaulieu +10
We measured precise masses of the host and planet in OGLE-2003-BLG-235 system, when the lens and source were resolving, with 2018 Keck high resolution images. This measurement is i…
The ACS Nearby Galaxy Survey Treasury II. Young Stars and their Relation to Halpha and UV Emission Timescales in the M81 Outer Disk
Stephanie M. Gogarten, Julianne J. Dalcanton, Benjamin F. Williams +11
We have obtained resolved stellar photometry from Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) observations of a field in the outer disk of M81 as part of the ACS…
The Detailed Science Case for the Maunakea Spectroscopic Explorer: the Composition and Dynamics of the Faint Universe
Alan McConnachie, Carine Babusiaux, Michael Balogh +173
MSE is an 11.25m aperture observatory with a 1.5 square degree field of view that will be fully dedicated to multi-object spectroscopy. More than 3200 fibres will feed spectrograph…
The ACS LCID project. IX. Imprints of the early Universe in the radial variation of the star formation history of dwarf galaxies
Sebastian L. Hidalgo, Matteo Monelli, Antonio Aparicio +8
Based on Hubble Space Telescope observations from the Local Cosmology from Isolated Dwarfs project, we present the star formation histories, as a function of galactocentric radius,…
