The spatial distribution of stars in the Local Group dwarf irregular galaxy NGC 6822 has been studied, using recent positions and deep photometry for about 15,000 stars in the galaxy. Based on photometrical data, OB stars and red stars could be studied separately. Spatial statistical tools have been applied to the analysis of the spatial structure. ...

... Recent studies on X-ray absorption variability on time scales of hours/days demonstrate that the X-ray "torus" is made of clouds with the same density and distance from the center as the BLR emission line clouds, thus suggesting a close link between the BLR and the X-ray circumnuclear absorber. ... The idea is that the results of these observational studies will be fundamental for a better physical description of the absorbers and, therefore,for a better knowledge of the actual structure of the BLR....
