Four of the five galaxies revealed synchronized bursts of star formation in the nuclei 1­2 Gyr ago. The only galaxy, in which the ages of stellar population in the nucleus and in the bulge coincide (i.e. the nuclear burst of star formation did not take place) is NGC 502, the farthest from the center of the group of all the galaxies studied. ...

... We present a new method of the ionospheric irregularity investigation based on using of temporal structure function of the phase of the vertical sounding signal. ... Theoretical relation between structure functions of the phase variations and the irregularities can be obtained in the framework of a simple model of frozen irregularity horizontal drift. ... structure function ?? ... The irregularity structure function can be easily calculated if the irregularity spatial spectrum is known. ... Figure 1...
