The XMM Deep Survey in the CDF-S VII. UV catalogue of the Optical Monitor observations
M. Antonucci, A. Talavera, F. Vagnetti +5
The XMM-Newton X-ray observatory has repeatedly observed the CDFS in 33 epochs (2001-2010) through the XMM-CDFS Deep Survey. During the X-ray observations, XMM-OM targeted the cent…
Selecting AGN through variability in SN datasets
K. Boutsia, B. Leibundgut, D. Trevese +1
Variability is a main property of active galactic nuclei (AGN) and it was adopted as a selection criterion using multi epoch surveys conducted for the detection of supernovae (SNe)…
Color Variability of AGNs
F. Vagnetti, D. Trevese
Optical spectral variability of quasars and BL Lac Objects is compared by means of the spectral variability parameter beta (Trevese & Vagnetti 2002). Both kinds of objects change t…
An X-ray and Optical Study of Matter Distribution in the Galaxy Cluster A 2319
D. Trevese, G. Cirimele, M. De Simone
A new analysis of velocity distribution, optical photometry and X-ray surface brightness from ROSAT PSPC data of the galaxy cluster A 2319 is presented. The temperature profile der…
The Variability of Quasars. II. Frequency Dependence
A. Di Clemente, E. Giallongo, G. Natali +2
The variability of 30 PG quasars has been observed in the red band during three years. A rest-frame structure function analysis shows an increase of variability with the time inter…
