Re:NGC 7079
4.11 NGC 7079
NGC 7079 is a weakly barred SB0 galaxy, a member of an interacting pair.
Bettoni & Galletta (1997) detected a counterrotating disk-like structure
of ionized gas which extends up to a radius of r = 2 kpc. The radial
velocities for the gas span from 2600 km s^-1^ to 2800 km s^-1^. The
stellar kinematics is typical of an undisturbed disk. The measured radial
velocities (up to r = 4.5 kpc) range from v ~ 2500 km s^-1^ to
v ~ 2900 km s^-1^ and give a v_sys_ = 2680 km s^-1^ and a central velocity
dispersion of 150 km s^-1^. No X-ray emission has been detected from this
galaxy; the IRAS satellite detected infrared emission.
The J = 2 - 1 and J = 1 - 0 lines of CO are detected in this galaxy,
showing the presence of molecular gas (see Fig. 1). The line profiles,
~170 km s^-1^ wide at zero power, are centered on the galaxy systemic
velocity, derived from optical data. The linewidths of both CO lines agree
satisfactorily with the velocity range measured for the counterrotating
ionized gas. In contrast, the CO widths are much smaller than the velocity
interval measured in the stellar lines. This may indicate that H_2_ gas is
confined to the inner portion of the galaxy and that it shares the same
kinematics as the counterrotating ionized gas. The inferred molecular gas
content is M_mol_ ~ 1.2 x 10^8^ M_sun_ up to r = 2 kpc.

Re:NGC 7079
This galaxy is a member of a group (Garcia 1993) and is a member of a physical
pair (# 351, Reduzzi & Rampazzo 1995), it has been classified as SB0(s)0 by RC3
and SBa by RSA. The bar in this galaxy is not very strong.
For this galaxy Bettoni & Buson (1987) indicate the presence of faint emission
lines; in our spectra it has been possible to measure only the O[III]
{lambda}=5007 A line, in the nuclear region within 15 arcsec. From our
measurements we found that the gas is in counter-rotation with respect to the
stars along all the four observed position angles. Probably we are observing a
very small disk of gas, whose maximum extension is ~15" (along the apparent
major axis).

NGC 7079 shows the earliest of the form
where the central bar is evident and the external
spiral arms are developed into a multi-armed
spiral pattern (the MAS subtype) of the (r) type
where the arms emerge tangent to the edge of a
disk. The "ring" here is the rather sharp division
between the central and the outside regions. The
division may be subjective; a measured
luminosity profile is needed.
The insert print shows the presence of the
type of bar where the two ansae that are attached
to the central bulge define the bar. (Note here
that the orientation of the central bulge differs
from the position angle of the outer disk - the
twist is continuous from the center outward.)
A rudimentary multiple-armed spiral pattern
exists in the outer envelope which is identified
here as the disk. Part of the spiral pattern
is defined by a thin dust lane, seen on the right
side of the image in the outer disk which is well
visible on this print.

extremely faint corona.

Re:NGC 7079
Spectrum:
Velocity is mean of 2 discordant values both from Source M1, V = 3007 and 2630,
(Observatory, 87, 224, 1967 and Observatory 89, 21, 1969).

Re:MCG -07-44-022
Type: deV - SB(s)0o.
Redshift: +2,624 km/sec (Catchpole et al., Obs. 89, 21, 1969)
+3,000 km/sec (Evans, Obs. 87, 224).

Re:NGC 7079
Very bright elongated nucleus (tilted) on a bright, cigar-shaped bar:
0.55 arcmin x 0.25 arcmin. Traces of structure in a bright lens:
1.4 arcmin x 0.8 arcmin. Very faint envelope.
HA 88, 2 dimensions (0.5: arcmin x 0.5: arcmin, series a') are for the
nucleus only.

SB(s)0^o
(Plate 9)
Small bright nucleus in short and bright bar, surrounded by very
faint traces of spiral arcs in lens; extensive envelope.
Compare with NGC 1291 (Plate 12) and NGC 4262 (Plate 13).
