The XMM-Newton long look of NGC 1365: uncovering of the obscured X-ray source
G. Risaliti, M. Salvati, M. Elvis +10
We present an analysis of the extreme obscuration variability observed during an XMM-Newton 5-days continuous monitoring of the AGN in NGC 1365. The source was in a reflection-domi…
The Reddest DR3 SDSS/XMM Quasars
Monica Young, Martin Elvis, Guido Risaliti
We have cross-correlated the SDSS DR3 Schneider et al. (2005) quasar catalog with the XMM-Newton archive. Color and redshift selections (g - r > 0.5 and 0.9 z < 2.1) result in a sa…
The evolution of the mass-metallicity relation at z~3
R. Maiolino, T. Nagao, A. Grazian +14
We present preliminary results of an ESO-VLT large programme (AMAZE) aimed at determining the evolution of the mass-metallicity relation at z~3 by means of deep near-IR spectroscop…
The X-ray emission of the most luminous 3CR radio sources
M. Salvati, G. Risaliti, P. Veron +1
We investigate the X-ray properties of the most luminous radio sources in the 3CR catalogue, in order to assess if they are similar to the most luminous radio quiet quasars, for in…
3-5 micron spectroscopy of obscured AGNs in ULIRGs
E. Sani, G. Risaliti, M. Salvati +6
We present the results of infrared L-band (3-4 micron) and M-band (4-5 micron) VLT-ISAAC spectroscopy of five bright Ultraluminous InfraRed Galaxies (ULIRGs) hosting an AGN. From o…
New flaring of an ultraluminous X-ray source in NGC 1365
R. Soria, A. Baldi, G. Risaliti +4
We have studied a highly variable ultraluminous X-ray source (ULX) in the Fornax galaxy NGC 1365, with a series of 12 Chandra and XMM-Newton observations between 2002 and 2006. In…
