*** Title: Herschel high-z sub-millimeter galaxies and gravitational lenses: H2O, a new diagnosis of their starburst [#wea7c393]
*** Title: A unifying view of AGN sub-pc scale structure as directly revealed by infrared interferometry [#h7388737]

 Abstract: Herschel extragalactic wide surveys which have observed about 1000 deg2, 
 are discovering  hundreds of thousands of high-z dusty sub-millimetrer galaxies, 
 and hundreds of high-z sub-millimeter strongly lensed galaxies. Gravitational magnification 
 there allows a gain by an order of magnitude in sensitivity in studying sub-millimeter galaxies 
 at high redshift (z~1-5).  I will first summarize the main results of these submm surveys, 
 and the strategy for identifying, characterizing and following up these sources. I will mainly 
 highlight strongest lenses, highest redshift sources ( z~ 4-6) , and possible proto-clusters 
 detected by Planck and Herschel.
 
 The easy detection of H2O lines redshifted into millimetre atmospheric windows is a good illustration. 
 I will first evoke Herschel results on H2O emission in local Ultra-Luminous Infrared Galaxies 
 (ULIRGs, SFR > 100 Mo/yr). Then millimetre detections of H2O lines will be presented 
 in similar objects at high-z. Observing a dozen of strong lenses from the H-ATLAS survey 
 with IRAM interferometer, we have shown that H2O is easily detectable at all high redshifts. 
 We show that the J=2 H2O line luminosity increases as LIR1.1-1.2. H2O lines provide thus 
 an important diagnosis in extreme starburst and possibly AGN conditions of warm gas 
 of these galaxies, especially those with LIR ~10^13 Lo (SFR>1000 Mo/yr), which have 
 no local equivalents but are abundant at z ~ 2-4. The weaker emission obtained 
 from the first results of the extension of the observations at J=3 levels might indicate that 
 the J=2 emitting medium is more extended than the cores of local ULIRGs. However, 
 modelling H2O emission remains difficult since complex processes take place such as 
 IR radiation transfer, shocks, cosmic rays, AGN feedback and XDR chemistry, outflows, etc. 
 Finally, I will evoke the rich prospects with ALMA for various possible extensions of such studies.
 Abstract: One of the big reasons why the progress in our understanding of the AGN mass 
 accretion process has been very slow is the absolute lack of appropriate spatial resolutions. 
 However, long-baseline interferometry in infrared wavelengths has been breaking the ground 
 over the last several years. First I will review the recent findings in the interferometric studies 
 of the innermost dusty structure in AGNs both in the near- and mid-infrared. Based on these 
 studies, I will show that a unifying view of the sub-pc scale structure is now emerging, 
 where the radiation pressure on dust grains is playing a central role in forming the structure. 
 I will conclude with the future prospects for sub-mm and infrared interferometric studies of AGNs.
