1. 2009MNRAS.397.2148G
Re:NGC 4564
Cote et al. (2006) identified this S0 galaxy as hosting both an NC and a BH;
although they were unable to measure the brightness of its NC. From the surface
brightness, colour and ellipticity profile for NGC 4564 (VCC 1664) in fig. 61
from Ferrarese et al. (2006b), one can discern that this S0 galaxy has a
relatively blue (g-z = 1.52) nucleus and a large-scale stellar disc which
starts to dominate beyond ~5 arcsec. However, no reliable structural
decomposition is available.

Re:NGC 4564
This highly elongated galaxy shows isoindex contours of the Mg b and the Fe
indices which are more flattened than the isophotes, indicating that the bulge
and disc of this galaxy have different stellar populations.

Re:NGC 4564
No significant emission is detected in this galaxy.

Re:VCC 1664
VCC 1664 (NGC 4564).There appears to be a faint nucleus in the color image,
although its presence is not obvious in the individual images. The galaxy
becomes quite disky beyond 10".

5. 2004MNRAS.352..721E
Re:NGC 4564
NGC 4564: This flattened galaxy shows the signature of a disc-like
component in the pinched V map, anticorrelated with h 3 (Bender et
al. 1994; Halliday et al. 2001). The large h_3_ amplitude along the major
axis outside ~5 arcsec is, however, not observed by Pinkney et
al. (2003) who also measured significantly negative h_4_.

Re:NGC 4564
A13 NGC 4564
NGC 4564 is a member of the Virgo cluster and classified as E6 in both
RC3 and RSA. Measurements of v, {sigma}, h_3_ and h_4_ are given in
Fig. A14. This galaxy has been studied by vdB94 using HST photometry and
in Fig. A15 major axis measurements of h_3_ obtained here are compared
with the photometric measurements of {epsilon}, PA and a_4_ from vdB94.
Non-symmetric LOSVDs are detected along the major axis by non-zero
h_3_ for |r| >~ 5 arcsec. h_4_ is consistent with zero. For the minor axis
h_3_ is non-zero for -9 arcsec <~ r <~ -5 arcsec and r ~ 9 arcsec. h_4_ is
positive for |r| >= 5 arcsec.
In Fig. A15, the most interesting results from the photometry are the
measurement of negative a_4_ and hence boxiness for r ~ 2 arcsec, and
measurement of disciness for |r| >~ 10 arcsec, isophote twisting for
r < 2.5 arcsec, and gradually increasing measurement of {epsilon} with
radius. The measurements of a_4_ for different radii suggest that two
separate components are being detected: within the inner 6arcsec the
measurements of boxy isophotes are consistent with existence of a central
bulge; disciness for r >~ 10 arcsec, where rotation is still measured to
increase with radius, and the gradual increase in {epsilon} with radius,
are consistent with the detection of a disc component. Measurements are
consistent with detection of a disc component embedded within a more slowly
rotating bulge.

NGC 4564 is in the southeastern corner of subcluster A of the
Virgo Cluster complex in a rich field of mixed morphology. The Sc
galaxies NGC 4567 and NGC 4568 (panel 281) are the nearest Dreyer
No evident disk is present. The type is pure E6.

Re:NGC 4564
NGC 4564 is highly elongated in the outer parts. The ellipticity
reaches a maximum of ~0.6 between 30" and 40" (Bender et al. 1988; Caon
et al. 1990). Further out the ellipticity decreases again. We find that
the ellipticity decreases to 0.16 at 0.5". Outside 10" the isophotes are
disky (consistent with Bender et al. 1988). This behavior of the
ellipticity profile is characteristic for a S0 (Michard 1984, cf. our
discussions of NGC 4342, NGC 4570, and NGC 4623). Around 2" the isophotal
parameters are very irregular, but the residual map does not indicate the
nature of the distortion. Gas and or dust might be responsible although
again Roberts et al. (1991) find no indication for either.

Re:NGC 4564
NGC 4564: This galaxy shows a clear photometric evidence of bulge-disk
segregation and a large diskyness (see Fig. 3 above). It might very well
have been classified SA0, although the RSA and RC2 agrees to call it E6.

10. 1994A&AS..105..341G
Re:NGC 4564
This galaxy has a fairly prominent stellar disk along its apparent major
axis (cf. Paper I). Our H{alpha}+[NII] image shows emission in its
nucleus, but we do not have spectra to confirm this.

11. 1994A&AS..104..179G
Re:NGC 4564
Fairly prominent stellar disk, aligned with the major axis; C4 parameter
up to +0.04.
