YOUNG STELLAR NUCLEI IN LENTICULAR GALAXIES: NGC 5574 AND NGC 7457 1 O. K. Sil'chenko 2 Sternberg Astronomical Institute, Universitetsky Pr. ... The compact nuclei of the galaxies appear to be chemically distinct: in NGC 5574 the nucleus is distinguished by a higher than solar irontomagnesium ratio, and in NGC 7457 a drop of mean stellar met allicity by a factor of 2 exists between the nucleus and the bulge. ... The bulges in NGC 5574 and NGC 7457 have rather young stellar populations. ...

IPI_MTS is a program for 1D automatic and manual interpretation of magneto-telluric and frequency sounding curves. The main advantage of this program is manual interpretation. You could change parameters of model in worksheet or drag-and-drop the part of resistivity curve (blue). Simultaneously, You could see how new parameter fits with field curve and another models of profile to choose optimal model from equivalent ones. ... Download FREEWARE-version of IPI_MTS (270K) . ...
