The ESO-Max Planck photometric and spectroscopic survey in the south: EMPhaSSiS

EMPhaSSiS is a photometric and spectroscopic survey of the disk of the Milky Way. The survey covers 33 fields in the 3rd quadrant of the Milky Way and probes every ten degrees in Galactic Longitude between l = 180<SUP>∘</SUP> – 280<SUP>∘</SUP> and at Galactic Latitudes of b = -20<SUP>∘</SUP>, – 30<SUP>∘</SUP> and – 40<SUP>∘</SUP>. Each field is observed in four filters, U, B, V and R, reaching depths of 21.5, 24.0, 23.5 and 23.5 respectively. Spectroscopic observations have been carried out in 11 of these fields and in so doing, main sequence turn-off stars are being traced into the...

AGN-Host Galaxy Connection: Morphology and Colours of X-ray Selected AGN at z &#60; 2

The connection between AGN and their host galaxies has been widely studied over recent years, showing it to be of great importance for providing answers to some fundamental questions related with AGN fueling mechanisms, their formation and evolution. Using X-ray and one of the deepest broad-band optical data sets, we studied morphology and colours in relationship with X-ray properties for sources at redshifts z < 2.0, using a sample of 262 AGN in the Subaru/XMM-Newton Deep Survey (SXDS). Morphological classification was obtained using the galSVM code, one of the new methods useful...
