(a) Metallicity function and relations between (b) metallicity and radial velocity, (c) metallicity and maximum distance from the Galactic plane,and (d)metallicity and variability period for RR Lyrae variables in the initial sample.The curve in the first graph is the maximum-likelihood approximation of the distribution using a sum of two normal curves with the indicated means,dispersions,and total numbers. ... next figure | privious figure . ...

... 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....
