Notes for object NGC 3626

10 note(s) found in NED.


1. 2005MNRAS.362.1319L
Re:NGC 3626
NGC 3626. In RC3, this galaxy is classified as a non-barred system with an outer
ring. However, both the q profile and the Fourier analysis show the presence of
a bar at r< 45 arcsec, having a morphology with ansae at the two ends of the bar
(Fig. 5). This galaxy has also an inner elliptical, detected as a bar-like
structure at r= 5 arcsec by the Fourier analysis, and as an elliptical feature
in the unsharp mask. The position angle of this structure deviates from that of
the main disc by 10{degrees}, and might actually be an inner disc.

Re:NGC 3626
NGC 3626. This galaxy was found to have a bar and an elliptical inner structure,
which might be a secondary bar or an inner disc. Reasonable decompositions can
be made either by fitting both components or only the bar component, because the
inner elliptical structure does not affect the obtained B/T ratio. After
subtracting the model from the original image, the residuals are small,
manifesting mainly the spiral structure of this galaxy.

Re:NGC 3626
23. NGC 3626 is an Sa spiral of medium inclination. Ciri et al. (1995)
found that the gas in this galaxy is counter-rotating to the stars. This
is probably the remnant of a merging or accretion event. NGC 3626 shows a
prominent dust lane (ring) around the central bulge. The fit residuum shows
the corresponding substructure there.

This early Sa galaxy is often misclassed as
S0/Sa. It is classed as RS0 in the RC2, where the
low-surface-brightness outer regions are called a
ring. However, the outer structure is spiral, of
the same smooth type as in the other two galaxies
on this page.
The internal dust lane is nearly circular, as
in the S0_3_ types, but unlike these "earlier"
(smoother) S0 dust lanes, the lane here can be
traced for 360 deg around the image. The reason
for the complete dust ring seen in the image here,
contrasted to only the partial appearance of the
dust ring in S0_3_ galaxies shown in previous
pages, is undoubtedly the favorable inclination
aspect of NGC 3626 and its smaller bulge intensity,
reducing the contamination of the ring contrast
on the far side.
The arms are tightly wound, one arm nearly
merging with the other after turning 180 deg, as in
NGC 3269, above. The innermost set of the
outer arms is shown better in the print on the
next panel. Even fainter structures that may
have a spiral pattern exist beyond the faint arms
visible there and also in the print here when it is
viewed from a distance.

Compare the detail in the dust lane of NGC
3626 in this print with the image of the same
galaxy on the preceding panel. The plate used
here was taken in better seeing, and it is a yellow
emulsion (103aD) rather than blue. Compare it
also with the long-exposure image of the same
galaxy, below, where the smooth arms are well
shown.

This image is from the same plate shown on
the preceding page but printed to show the
smooth spiral arms. As mentioned on the preceding
page, there exist yet fainter structures beyond
the arms shown here. They are located as far
from the edge of the lens beyond the arms seen
here as those arms arc from the lens. A hint of
the outermost structure is most visible on this
print on the lower-right side of the image when
the print is viewed from a distance.

NGC 3626 has been shown on panel 63 to
illustrate the smooth outer arms of such early Sa
galaxies and on panel 64 to show the interior
dust circle. It is shown again here from a
short-exposure 200-inch plate to emphasize its
similarity to the other galaxies on this page in its
dust lane. NGC 3626 is nearly identical to NGC
3032 at the left in (1) the pattern of the dust, (2)
the resulting isolated adjacent luminous ring, and
(3) the outer very faint smooth spiral arms. The
very outer arms, seen here by viewing the print
from a distance and moving the head or eyes, are
more visible in NGC 3626 than in NGC 3032
because of the more favorable (larger) inclination
to the sight line.
