We present results from HST/STIS long-slit spectroscopy of the gas motions in the nuclear region of the Seyfert 2 galaxy NGC 5252. The observed velocity field is consistent with ga…
Night sky brightness at sites from DMSP-OLS satellite measurements
Pierantonio Cinzano, Cristopher D. Elvidge
We apply the sky brightness modelling technique introduced and developed by Roy Garstang to high-resolution DMSP-OLS satellite measurements of upward artificial light flux and to G…
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…
