Addressing Decadal Survey Science through Community Access to Highly Multiplexed Spectroscopy with BigBOSS on the KPNO Mayall Telescope
Caty Pilachowski, Carles Badenes, Stephen Bailey +87
This document summarizes the results of a community-based discussion of the potential science impact of the Mayall+BigBOSS highly multiplexed multi-object spectroscopic capability.…
The Star Formation & Chemical Evolution History of the Fornax Dwarf Spheroidal Galaxy
T. J. L. de Boer, E. Tolstoy, V. Hill +6
We present deep photometry in the B,V and I filters from CTIO/MOSAIC for about 270.000 stars in the Fornax dwarf Spheroidal galaxy, out to a radius of r_ell\sim0.8 degrees. By comb…
The Resolved Stellar Population in 50 Regions of M83 from HST/WFC3 Early Release Science Observations
Hwihyun Kim, Bradley C. Whitmore, Rupali Chandar +22
We present a multi-wavelength photometric study of ~15,000 resolved stars in the nearby spiral galaxy M83 (NGC5236, D=4.61Mpc) based on Hubble Space Telescope Wide Field Camera 3 o…
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…
Ultra Long Period Cepheids: a primary standard candle out to the Hubble flow
G. Fiorentino, G. Clementini, M. Marconi +7
The cosmological distance ladder crucially depends on classical Cepheids (with P=3-80 days), which are primary distance indicators up to 33 Mpc. Within this volume, very few SNe Ia…
The Star Formation & Chemical Evolution History of the Sculptor Dwarf Spheroidal Galaxy
T. J. L. de Boer, E. Tolstoy, V. Hill +6
We have combined deep photometry in the B,V and I bands from CTIO/MOSAIC of the Sculptor dwarf spheroidal galaxy, going down to the oldest Main Sequence Turn-Offs, with spectroscop…
