As a result, a common magnitude scale (contour lines on the maps above, or color scale on Fig.1) will poorly display the short-duration events in a signal. Normalizing each line of the map (fixed duration) so it has unit variance (in effect dividing the energy map by the mean energy spectrum) at each duration restores more details of small-scale activity (Fig. ...

... The picture shows sketches of the optical and ultraviolet (top, left) and X-ray (top, right) spectra of a typical quasar or AGN (Active Galactic Nucleus). These spectra are full of sharp features due to the interaction of atoms with light ('atomic features'). They can be high (= bright) points, called 'emission lines' or low (= dark) points, called 'absorption lines' . ... Broad Emission Lines ("BELs") [seen in 100% of AGN], . ... Broad Absorption Lines ("BALs") [see in only 10% of AGN], . ...

... R-band images obtained at 0.8 arcsec seeing conditions have allowed us to separate foreground star from point-like extragalactic source and estimate their brightness separately. ... To study the nature and properties of the source, we observed it under high spatial resolution. ... CONCLUSION RTT150 optical observations with sub-arcsecond seeing and low resolution spectra confirm the hypothesis of superposition of a radio source onto a `normal' F/G galactic star proposed by [1]. ...
