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…
Most hard X-ray selected quasars in Chandra Deep Fields are obscured
J. X. Wang, P. Jiang, Z. Y. Zheng +13
Measuring the population of obscured quasars is one of the key issues to understand the evolution of active galactic nuclei (AGNs). With a redshift completeness of 99%, the X-ray s…
The UV spectrum of HS1700+6416 II. FUSE observations of the HeII Lyman alpha forest
C. Fechner, D. Reimers, G. A. Kriss +11
We present the far-UV spectrum of the quasar HS1700+6416 taken with FUSE. This QSO provides the second line of sight with the HeII absorption resolved into a Ly alpha forest struct…
HST/ACS Multiband Coronagraphic Imaging of the Debris Disk around Beta Pictoris
D. A. Golimowski, D. R. Ardila, J. E. Krist +40
(Abridged.) We present F435W (B), F606W (Broad V), and F814W (Broad I) coronagraphic images of the debris disk around Beta Pictoris obtained with HST's Advanced Camera for Surveys.…
Evolution of the Color-Magnitude Relation in High-Redshift Clusters: Blue Early-Type Galaxies and Red Pairs in RDCS J0910+5422
S. Mei, J. P. Blakeslee, S. A. Stanford +17
The color-magnitude relation has been determined for the RDCS J0910+5422 cluster of galaxies at redshift z = 1.106. Cluster members were selected from HST ACS images, combined with…
Seventy-One New L and T Dwarfs from the Sloan Digital Sky Survey
K. Chiu, X. Fan, S. K. Leggett +5
We present near-infrared observations of 71 newly discovered L and T dwarfs, selected from imaging data of the Sloan Digital Sky Survey (SDSS) using the i-dropout technique. Sixty-…
