1. 2006ApJS..164...52S
Re:NGC 5054
The radio image of this galaxy, presented in the top panel of Figure 15, shows
stronger emission at the nucleus, surround by a region of fainter and diffuse
emission, with a radius of 40".

Re:NGC 5054
NGC 5054 (Fig. 8j, available in the online version). Another more
typical group of SAB-type galaxies are those clearly having no bar, the
non-axisymmetric forces being rather induced by ovals. Such galaxies
are, for example, NGC 3893, 4254, 5054, 5085, 6215, 7205 and 7412, of
which NGC 5054 is shown as an example. The oval is seen at r < 20
arcsec having nearly constant m = 2 phase in the oval region and a
bar-like 'butterfly pattern'. The oval can be distinguished from a bar
by its small major-to-minor axial ratio, and also by the relatively
large angle between the two amplitude maxima in the butterfly pattern
({alpha} = 45deg). The tangential forces induced by the oval are
relatively weak for this galaxy, which is generally the case also for
the other galaxies with ovals in our sample.

Re:NGC 5054
NGC 5054 (LW)
There is some star formation in the circumnuclear disk, particularly
to the south and west of the nucleus, but these star formation regions
are not obviously associated with any of the many nuclear dust
spirals.

Re:NGC 5054
The morphological classification as determined by us is indicated in
parentheses next to the galaxy name, with our "chaotic circumnuclear
dust" (C) category now not including those galaxies with obvious dust
lanes (DL). Where the classification has already been made by Martini
et al. (2003), we indicate this with "-mp."

Figure 15 (top).
Spectra: A continuum obvious only in the NUC spectrum. There are
patchy extended emission lines. H{alpha} in OFF 2 shows the best
evidence for rotation.
Images: Star-forming regions to the south of nucleus?

Re:NGC 5054
NGC 5054.---SABc: Bright, round nuclear source threaded by a nuclear
bar. This causes the outer bulge isophotes to appear elliptical.
There is an inner disk, with no spiral structure. Beyond this, there
is a prominent, grand-design three-armed spiral pattern. The arms are
all well defined and have numerous star-forming knots. The arm origin
points are spaced ~120deg apart, so there is no evidence that this
galaxy has two main arms plus an anomalous arm. The N/NE arm has the
steepest pitch angle, but all are fairly loosely wound. All the arms
can be followed for ~180deg at the faintest level. Beyond ~20deg, the
N/NE arm is quite faint.

NGC 5054 is an outlying member of the NGC 5044 Group (Ferguson
and Sandage 1990, Fig. 8) whose mean redshift is = 2048 km/s.
However, the redshift v_o = 1524 km/s of NGC 5054 is different enough
from the mean group redshift to suggest a foreground location.
The two high-surface-brightness main arms are studded with HII
regions, the largest several of which resolve at about the 2" level.
Note the faint surface brightness of the spiral pattern at the
outer extensions of the main arms.

Re:NGC 5054
Pair with small anonymous SBm? sp at 2.7 arcmin north.

= NGC 5054
SA(s)bc (RC1)
foreground object in the NGC 5044 Cluster;
MCG-03-34-040 attached
at 2.6, 349, 1.0 x 0.15, Sc-Irr, background?
no certain evidence of interaction;
small stellar object
at 2.6 north-following appears to have a faint tail
directed away from NGC 5044

Re:MCG -03-34-039
Interacting pair with MCG -03-34-040. {rho}=2.6 arcmin. Forms with
MCG -03-34-034 the main part of the cluster. The north arm of
MCG -03-34-039 is directed towards and stretches almost to MCG -03-34-040.
The cluster is interesting because it has 7 bright (next to brightest)
galaxies with their sides turned towards us. Type: vB - Sbnt II:, Morg
- fS4 and fgS4, Vauc - SA(s)bc. MCG -03-34-040 according to Vauc - SBm.

Re:NGC 5054
Small, very bright, complex nucleus. Pseudo (r?): 0.85 arcmin x 0.5 arcmin.
3 main, bright, partially resolved arms.
Pair with a small anonymous SBm? spiral at 2.7 arcmin north.
Near the NGC 5049 Group.
