... Chandra Survey . ... Optical Database . ... The R (1200 sec total exposure time), I (540 sec), and Halpha (4500 sec) images show a source at RA(J2000)=17h 49m 55.34s, Dec(J2000)=-29d 19m 19.7s. At an offset of 0.16", this is consistent with the Chandra position. ... Given the error on the Faulkes position (0.3"), and the absence of other sources in the Mosaic and Faulkes images within 1.8" of the Chandra position, we consider our Mosaic source and the proposed optical counterpart to be the same. ...

This could be considered an underestimate, because QSOs are easier to identify than early-type galaxies which appear to dominate the red sample so the 14 objects with unidentified spectra are most likely to be galaxies.) ...

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. ...
