Gauging the dark matter fraction in a S0 galaxy at z=0.47 through gravitational lensing from deep HST/ACS imaging
G. Covone, M. Paolillo, N. R. Napolitano +9
We analyze a new gravitational lens, OAC-GL J1223-1239, serendipitously found in a deep I-band image of the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS). The lens…
The true nature of CSL-1
M. V. Sazhin, M. Capaccioli, G. Longo +5
On January 12 2006, the Hubble Space Telescope observed the peculiar double extragalactic object CSL-1, suspected to be the result of gravitational lensing by a cosmic string. The…
AGN Host Galaxies at z~0.4-1.3 : Bulge-dominated and Lacking Merger-AGN Connection
N. A. Grogin, C. J. Conselice, E. Chatzichristou +13
We investigate morphological structure parameters and local environments of distant moderate-luminosity active galactic nucleus (AGN) host galaxies in the overlap between the HST/A…
The supermassive black hole in Centaurus A: a benchmark for gas kinematical measurements
A. Marconi, G. Pastorini, F. Pacini +5
We present new HST/STIS observations of Centaurus A. [SIII] 9533A was used to study the kinematics in the nuclear region with a 0.1" spatial resolution. The STIS data and the VLT/I…
Prevalence of X-ray variability in the Chandra Deep Field South
M. Paolillo, E. J. Schreier, R. Giacconi +2
We studied the X-ray variability of sources detected in the Chandra Deep Field South (Giacconi et al. 2002), nearly all of which are low to moderate z AGN (Tozzi et al. 2001). We f…
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…
