1BrandtNielniel@astro.psu.eduThe Pennsylvania State UniversityDeep-Survey Constraints on X-ray Outbursts from Stellar Tidal DisruptionsTransient X-ray outbursts from galactic nuclei are likely caused by inevitable fueling events of supermassive black holes when a star or gas cloud is tidally disrupted and partially accreted. They may be a primary fueling mechanism for moderate-luminosity active galaxies. We present new constraints on the rate of such outbursts, utilizing the multi-epoch nature of the Chandra Deep Fields. Specifically, we constrain outbursts with harder X-ray spectra, higher redshifts, and lower X-ray luminosities than in our past work. We also discuss future plans and implications for the Black Hole Finder Probe, Lobster, eROSITA, LSST, and JDEM.oral Monday: Type I and II AGN, Absorption, XBONGs, Tuesday: AGN correlation functions, LSS, environments7
2BrusaMarcellamarcella@mpe.mpg.deMPE - Max Planck Institut fuer Extraterrestrische PhysikThe AGN content of the COSMOS: the XMM-Newton viewThe XMM-Newton wide-field survey in the COSMOS field (XMM-COSMOS) is expected to be an important step forward in the study of the physics and evolution of AGN, especially for what concern high redshift obscured quasars. I will discuss the survey strategy and the main scientific objectives expected from the full exploitation of the truly multiwavelength dataset available (including HST, NIR, Spitzer and VLA data). I will also present the most important results obtained from the analysis of the first year XMM-Newton observations. In particular, I will concentrate on the multiwavelength properties of about 1400 X-ray sources detected over an area of ~2 deg^2, and I will show a few examples on how the combined use of different datasets is crucial to fully characterize the AGN source population.oralMost important questions left to answer: - luminosity function of z>3 quasars: current samples, uncertainities in the extrapolation from lower redshift, how to increase the statistics, selection effects, problem with optical identification - role of AGN in galaxy evolution: how can observations help? statistics of AGN in high-z otherwise "normal" galaxies (EROs, BzKs, LBG etc.): need quantitative estimatesMonday: X-ray luminosity functions and evolution, Tuesday: AGN correlation functions, LSS, environments7
3ComastriAndreaandrea.comastri@oabo.inaf.itINAF - Osservatorio Astronomico di BolognaEverything you always wanted to know about X-Ray Background but were afraid to askAfter a review of AGN synthesis models for the XRB I will discuss the multiwavelength properties of the XRB sources with special enphasys on peculair/extreme objects such as EROs EXOs XBONG and Compton Thick AGN. The wavelength dependence of selection criteria to obtain an almost complete census of accreting SMBH will be critically discussed.oral Monday: Type I and II AGN, Absorption, XBONGs, Tuesday: AGN correlation functions, LSS, environments7
4FioreFabriziofiore@oa-roma.inaf.itINAF-OARThe multiwavelengh survey of the ELAIS-S1 fieldBoth X-ray, optical and infrared observations are needed to provide a full census of AGN. They can be used to select samples of today still elusive Comptonthick AGNs. Deep surveys in these three wide bands are a key ingredient to obtain an unbiased AGN "bolometric" luminosity function. The central 0.6deg2 region of the ELAIS-S1 field is one of the few fields with deep X-ray (XMM, Chandra), optical (B,V,R,I,z, VLT-VIMOS and FORS2 spectroscopy), near infrared (J,K) and mid-infrared (IRAC, MIPS) coverage. It is therefore particularly well suited to test strategies to find both unobscured and moderately obscured AGN shining in X-rays and highly obscured AGN with faint X-ray emission but shining in the infrared. These strategies will then be applied on wider fields like the COSMOS field as soon the Spitzer and Chandra coverages will be ultimated.oral Monday: X-ray luminosity functions and evolution, Tuesday: AGN correlation functions, LSS, environments7
5SchartelNorbertNorbert.Schartel@sciops.esa.intXMM-Newton SOC, ESAA new observing mode for XMM-NewtonWhen XMM-Newton moves from one target to another its cameras continue to observe. These observations, performed when XMM-Newton was slewing, allowed the compilation of a catalogue: the XMM-Newton Slew Survey. Reflecting these positive experiences, the XMM-Newton SOC started the development of a new observing mode, which basically is a slow slew- observing mode. The talk gives an overview of the slew survey, outlines the status of the development of the new observing mode and iterates the scientific potential especially with respect to large area surveys.oral Monday: Type I and II AGN, Absorption, XBONGs, Tuesday: Cluster Formation and Evolution7
