A Study of the Dark Core in A520 with Hubble Space Telescope: The Mystery Deepens
M. J. Jee, A. Mahdavi, H. Hoekstra +4
We present a Hubble Space Telescope/Wide Field Planetary Camera 2 weak-lensing study of A520, where a previous analysis of ground-based data suggested the presence of a dark mass c…
Tracing the Peculiar Dark Matter Structure in the Galaxy Cluster CL 0024+17 with Intracluster Stars and Gas
M. J. Jee
ICL is believed to originate from the stars stripped from cluster galaxies. They are no longer gravitationally bound to individual galaxies, but to the cluster, and their smooth di…
Hubble Space Telescope Weak-lensing Study of the Galaxy Cluster XMMU J2235.3-2557 at z=1.4: A Surprisingly Massive Galaxy Cluster when the Universe is One-third of its Current Age
M. J. Jee, P. Rosati, H. C. Ford +8
We present a weak-lensing analysis of the z=1.4 galaxy cluster XMMU J2235.3-2557, based on deep Advanced Camera for Surveys images. Despite the observational challenge set by the h…
Discovery of a Very Bright Strongly-Lensed Galaxy Candidate at z ~ 7.6
L. D. Bradley, R. J. Bouwens, H. C. Ford +11
Using HST and Spitzer IRAC imaging, we report the discovery of a very bright strongly lensed Lyman break galaxy (LBG) candidate at z~7.6 in the field of the massive galaxy cluster…
Discovery of a Ringlike Dark Matter Structure in the Core of the Galaxy Cluster Cl 0024+17
M. J. Jee, H. C. Ford, G. D. Illingworth +13
We present a comprehensive mass reconstruction of the rich galaxy cluster Cl 0024+17 at z~0.4 from ACS data, unifying both strong- and weak-lensing constraints. The weak-lensing si…
GALEX UV Color-Magnitude Relations and Evidence for Recent Star Formation in Early-type Galaxies
S Yi, SJ Yoon, S Kaviraj +32
We have used the GALEX UV photometric data to construct a first near-ultraviolet (NUV) color-magnitude relation (CMR) for the galaxies pre-classified as early-type by SDSS studies.…
