The Luminosity Functions of the Galaxy Cluster MS1054-0321 at z=0.83 based on ACS Photometry
Tomotsugu Goto, Marc Postman, Nicholas J. G. Cross +41
We present new measurements of the galaxy luminosity function (LF) and its dependence on local galaxy density, color, morphology, and clustocentric radius for the massive z=0.83 cl…
The Transformation of Cluster Galaxies at Intermeidate Redshift
N. L. Homeier, R. Demarco, P. Rosati +17
We combine imaging data from the Advanced Camera for Surveys (ACS) with VLT/FORS optical spectroscopy to study the properties of star-forming galaxies in the z=0.837 cluster CL0152…
A Resolved Debris Disk around the G2V star HD 107146
D. R. Ardila, D. A. Golimowski, J. E. Krist +6
We present resolved scattered-light images of the debris disk around HD 107146, a G2 star 28.5 pc from the Sun. This is the first debris disk to be resolved in scattered light arou…
HST/ACS Coronagraphic Imaging of the AU Microscopii Debris Disk
John E. Krist, D. R. Ardila, D. A. Golimowski +5
We present {\it Hubble Space Telescope} Advanced Camera for Surveys multicolor coronagraphic images of the recently discovered edge-on debris disk around the nearby ( pc) M…
Strong Lensing Analysis of A1689 from Deep Advanced Camera Images
Tom Broadhurst, Narciso Benitez, Dan Coe +6
We analyse deep multi-colour Advanced Camera images of the largest known gravitational lens, A1689. Radial and tangential arcs delineate the critical curves in unprecedented detail…
Ultra Compact Dwarf galaxies in Abell 1689: a photometric study with the ACS
S. Mieske, L. Infante, N. Benitez +37
The properties of Ultra Compact Dwarf (UCD) galaxy candidates in Abell 1689 (z=0.183) are investigated, based on deep high resolution ACS images. A UCD candidate has to be unresolv…
Measuring Fundamental Parameters of Substellar Objects. I: Surface Gravities
Subhanjoy Mohanty, Gibor Basri, Ray Jayawardhana +3
(abridged) We present an analysis of high resolution optical spectra for a sample of very young, mid- to late M, low-mass stellar and substellar objects in Upper Sco and Taurus. Ef…
X-ray Properties of Pre--Main-Sequence Stars in the Orion Nebula Cluster with Known Rotation Periods
Keivan G. Stassun, David R. Ardila, Mary Barsony +2
We re-analyze all archival Chandra/ACIS observations of the Orion Nebula Cluster (ONC) to study the X-ray properties of a large sample of pre--main-sequence (PMS) stars with optica…
A large population of 'Lyman-break' galaxies in a protocluster at redshift z=4.1
George K. Miley, Roderik A. Overzier, Zlatan I. Tsvetanov +1
The most massive galaxies and the richest clusters are believed to have emerged from regions with the largest enhancements of mass density relative to the surrounding space. Distan…
