A Study of the Reionization History of Intergalactic Helium with FUSE and VLT
W. Zheng, G. A. Kriss, J. -M. Deharveng +8
We obtained high-resolution VLT and FUSE spectra of the quasar HE2347-4342 to study the properties of the intergalactic medium between redshifts z=2.0-2.9. The high-quality optical…
ACS Observations of a Strongly Lensed Arc in a Field Elliptical
J. P. Blakeslee, K. C. Zekser, N. Benitez +15
We report the discovery of a strongly lensed arc system around a field elliptical galaxy in Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) images of a parallel fiel…
The Chandra Deep Field South: Optical Spectroscopy I
G. P. Szokoly, J. Bergeron, G. Hasinger +15
We present the results of our spectroscopic follow-up program of the X-ray sources detected in the 942 ks exposure of the Chandra Deep Field South (CDFS). 288 possible counterparts…
Discovery of Globular Clusters in the Proto-Spiral NGC2915: Implications for Hierarchical Galaxy Evolution
G. R. Meurer, J. P. Blakeslee, M. Sirianni +30
We have discovered three globular clusters beyond the Holmberg radius in Hubble Space Telescope Advanced Camera for Surveys images of the gas-rich dark matter dominated blue compac…
Tracing the large scale structure in the Chandra Deep Field South
R. Gilli, A. Cimatti, E. Daddi +16
We report the discovery of large scale structures of X-ray sources in the 1Msec observation of the Chandra Deep Field South. Two main structures appear as narrow (Delta_z < 0.02) s…
HST/ACS Coronagraphic Imaging of the Circumstellar Disk around HD1415659A
M. Clampin, J. E. Krist, D. R. Ardila +31
Multicolor coronagraphic images of the circumstellar disk around HD141569A have been obtained with the Hubble Space Telescope (HST) Advanced Camera for Surveys. B, V, and I images…
