1	Barger	Amy	barger@astro.wisc.edu	University of Wisconsin-Madison	Extragalactic Surveys	I will review our current understanding of the history of supermassive black hole accretion from deep and wide-area X-ray surveys. I will use these data to compute the growth of the supermassive black hole mass density and compare it with the locally determined values.	oral	For debate: which do we need more, additional large area surveys or pushing as deep as possible?

2	Gilfanov	Marat	gilfanov@mpa-garching.mpg.de	MPA, Garching	X-ray binaries and CXB.	We discuss contribution of X-ray binaries to the Cosmic X-ray Background. We show that given the cosmic star formation history and Lx-SFR relation for high-mass X-ray binaries, their contribution to the CXB energy flux in the 2-10 keV band can be as large as ~5%. A similar estimate for low-mass X-ray binaries gives an upper limit of a few per cent.	oral		Monday: 'Normal' Galaxies, Tuesday: Cluster Formation and Evolution	1
3	Koekemoer	Anton	koekemoe@stsci.edu	Space Telescope Science Institute	Probing AGN Populations beyond Redshifts 6 - 7 using Large X-ray Surveys	The advent of deep and wide multi-wavelength surveys provides unprecedented new opportunities to search for very high redshift active galactic nuclei by constructing samples of sources that are detected at X-ray wavelengths but completely undetected at optical wavelengths to very deep limits. I will describe recent work on constructing samples of candidate AGN at or beyond redshift 6 - 7, such as the `EXO's selected from deep multiband X-ray/HST/IR surveys such as GOODS, COSMOS and similar projects. The optical flux limits are combined with IR detections, together with X-ray fluxes, to model the spectral energy distributions of the sources and help discriminate intermediate-redshift interlopers from the rare number of likely high-redshift sources. The resulting constraints on the number of candidate AGN at or above redshift 7 are used to examine the evolution of the AGN luminosity function at high redshift, with corresponding implications for the co-evolution of ga! laxies and their central black holes.	oral		Monday: X-ray luminosity functions and evolution, Tuesday: AGN correlation functions, LSS, environments	1
4	Silverman	John	jsilverman@mpe.mpg.de	Max-Planck-Institut fur Extraterrestrische Physik	The evolution of supermassive black holes out to z ~ 5	We present a measure of the hard (2-8 keV) X-ray luminosity function of active galaxies to trace the growth of supermassive black holes out to early epochs. To do so, we have compiled a large AGN sample from published catalogs and the Chandra Multiwavelength Project (ChaMP) that significantly improves the statistics at z > 3. We discuss new analytic model fits that cover the full redshift range and enables us to determine the mass and accretion rate distributions at high redshift. We further address the improvements possible with current (e.g. E-CDF-S) and future (cCOSMOS) surveys with Chandra to improve the luminosity function at z > 4 and the low luminosity end at z > 1.5.	oral		Monday: X-ray luminosity functions and evolution, Tuesday: AGN correlation functions, LSS, environments	1
5	Tozzi	Paolo	tozzi@ts.astro.it	INAF - Osservatorio Astronomico di Trieste	Spectral analysis of X-ray sources in the CDFS	Deep X-ray surveys are providing crucial information on the evolution of AGN and galaxies. We review some of the latest results based on the X-ray spectral analysis of the sources detected in the Chandra Deep Field South, namely: i) constraints on obscured accretion; ii) constraints on the missing fraction of the X-ray background; iii) the redshift distribution of Compton-thick sources and TypeII QSO; iv) the detection of star formation activity in high-z galaxies through stacking techniques; v) the detection of large scale structure in the AGN distribution and its effect on nuclear activity. Such observational findings are consistent with a scenario where nuclear activity and star formation processes develop together in an anti-hierarchical fashion.	oral		Monday: Type I and II AGN, Absorption, XBONGs	1
6	Tzanavaris	Panayotis	pana@astro.noa.gr	National Observatory of Athens	The luminosity function and evolution of normal galaxies	We present initial results on the luminosity function and evolution of normal galaxies. We are using Chandra data from the deep fields CDFS-S and CDF-S as well as shallower data from the ECDFS and the XBOOTES. We are selecting normal galaxies using the following criteria: a) Lx<10^42 b) log(fx/fo) < -1 c) hardness ratio < 0. We present our results separately for early type and late type systems. Finally, we compare our results with previous Chandra findings as well as with the XMM luminosity function in the local Universe.	oral		Monday: 'Normal' Galaxies, Tuesday: Groups and Interactions	1
