Re:NGC 0488
NGC 488 is an unbarred Sb galaxy and it is the most elliptical-like
(featureless) object within our sample. NGC 488 has regular stellar and gaseous
kinematics, with regular rotation and velocity dispersion smoothly decreasing
outwards (Ganda et al. 2006). The line strength maps present high values for
Fe5015 and Mgb and low values for H{beta} over the central regions. As one can
note from the values reported in Table 2, this galaxy has the highest Fe5015 and
Mgb in the sample, and the lowest H{beta}. The ages are mainly old and the
metallicities high. This is indeed the most metal-rich galaxy in the sample (the
central metallicity from the one-SSP approach is ~= 0.49, then it decreases
outwards). This galaxy is well described by a one-SSP approach: as shown in Fig.
29 (first column) on the basis of our continuous star formation analysis, NGC
488 is very unlikely to have experienced a constant star formation over time;
the observed indices are instead reproduced by a short starburst, approximating
an SSP. The time-scale of star formation {tau} is short over the whole field.
From the profile in Fig. A1, we can see that the [Mg/Fe] profile is
approximately constant around the value ~=0.2: abundance ratios are slightly
supersolar, confirming the fact that this galaxy resembles an elliptical more
than the later objects in our sample. Other suggestions in this sense come from
the position it occupies in the diagrams in Figs 15, 16 and 19, where it lies in
the region occupied by the ellipticals.

NGC 488.---Sa (type example---see Fig. 3c): System nearly face-on.
Bright, circular nucleus, embedded in a large, slightly elliptical
bulge. The bulge and disk have the same P.A. There is a faint spiral
pattern, with thin, smooth tightly wrapped arm features embedded in a
smooth disk. There are no prominent star-forming knots.

Re:NGC 0488
NGC 488. NVSS did not detect this source. However, 54" resolution
observations at 1.4 GHz (Condon 1987) show a diffuse 7.6 mJy source-
the radio emission must have low surface brightness. Both our full
resolution and tapered map show only a very weak, ~0.3 mJy unresolved
core, at the optical center of the galaxy.

Re:UGC 00907
This diffuse radio source is not in the NVSS catalog; its flux density
is from Condon (1987).

Re:NGC 0488
NGC 488 - SN 1976G: one very red and bright extended patch (far off
North to the assumed SN position). It looks like a small tail
"departing" from the galaxy nucleus.

Re:NGC 0488
[N II] is visible in the red spectrum, along with an emission core to the
H{alpha} absorption line. Both of these emission lines show a double-
peaked profile, reflecting the steep rotation curve visible in the 2-D
spectrum.

NGC 488 is the prototype galaxy of the multiple-armed spiral
(MAS) type which can be traced throughout the spiral sequence from
early Sa to late Sd. Examples of galaxies of this type are NGC 2775
(Sa; panels 78, 87, S12), NGC 1398 (SBab; panels 120, 121), NGC 4380
(Sab; panel 117), NGC 2841 (Sb; panels 142, S4, S12), NGC 3521 (Sbc;
panel 188), NGC 4212 (Sc; panel 278), NGC 4647 (Sc; panels 51, 278,
S14), NGC 4689 (Sc; panel 277), and NGC 7793 (Sd; panels 321, S6).
The form consists of fragments of strings arranged in a spiral
pattern over the face of the disk. No fragment can be traced for more
than about half a revolution. The spiral pattern in NGC 0488 is very
tightly wound, and the individual segments are thin. The arms are
lumpy, clearly showing star formation confined to the arms
themselves. Star formation does not extend randomly over the disk.
The central bulge is large and smooth. The innermost spiral
pattern, partly burned out in the print on the facing panel, is
composed of dust lanes with the same spiral opening angle as the
luminous arms farther out.
In galaxies of this type later in the classification sequence,
the arms become thicker, the spiral opening angle is wider, and the
prominence of the central bulge is less.

The negative print of NGC 0488 here is made from the same plate
used on the preceding panel and in the Hubble Atlas. The image there
was printed to a different contrast and to a different scale.
An appreciation of the fragmented nature of the MAS type can be
gained by attempting to trace any individual fragment as a coherent
arm outward. The fragment soon disappears, to be replaced by an
adjacent but separate fragment.

NGC 0488 is of the NGC 2841 type but is slightly later, for the
spiral structure can be traced closer to the central regions.
There is a change in the characteristics of the spiral arms
close to the nucleus. The inner arms are very smooth in
texture with no indication of resolution into lumps. These
arms can be traced to within 25 sec (radius along the major
axis) of the center--about 9 mm on the illustration.
The amorphous inner arms can just be seen. As they
wind outward, they lose their smooth texture and become
"lumpy" with condensations. The luminous arms are
nearly circular, with regular dust lanes on their inside
edges. The distance modulus to NGC 0488 is about (m-M) = 32.4.
At this distance, the angular width of the arms
corresponds to 350 parsecs. The aveiage distance between
arms in the outer regions is about 1000 parsecs.
These values should be compared with values for typical
Sc galaxies given in the later sections of the Atlas.

Re:NGC 0488
Nearly round; 3' in diameter; very bright, almost stellar nucleus. An unusually
symmetrical, rather faint spiral. The whorls are very delicate, .and so close
together that at first sight they appear to be rings around the nucleus instead
of spiral whorls. 31 s.n.
