Re:NGC 0274
Pair [with NGC 275]
Sep 13/14, 1956
20 min
This is an unambiguous case of an encounter
of two disparate galaxy types, similar to NGC
1596/1602 on the preceding page. NGC 274
with a redshift of v_o = 1894 km/s is nearly
projected onto the image of NGC 275
[S pec(tides)], which has virtually the same
redshift, v_o = 1889 km/s. The angular separation
of the pair is 44". The redshift distance of 38
Mpc (H = 50) gives a very small projected linear
separation of 8 kpc.
NGC 274 has the morphology of a classical
S0_1_(0). Its image is undisturbed. There are no
tidal plumes, nor is the characteristic two-zone
circularly symmetric image distorted, as might be
expected if the encounter was progressing toward
merger, suggesting that the binary pair is
extended in the line of sight.
NGC 275 has the morphology of a late-type
spiral, but its form is not as regular as that of
most high-surface-brightness Sc galaxies. The
many knots, presumably HII regions, suggest
recent star formation.
The presence of a normal S0 galaxy in a
physical pair with a star-producing Sc galaxy
shows that S0 galaxies are not a result of sweeping
gas from a parent spiral to form an S0. If the
S0 morphology of NGC 274 was produced that
way, why was not its close companion NGC 275
affected equally? S0 galaxies are generic to the
Hubble sequence, not a result of later evolutionary
processes (Sandage 1983a).

Re:NGC 0274
= Holm 026b
Very small, extremely bright nucleus.
Projected on one arm of NGC 0275.
Interacting pair with NGC 0275 at 0.8 arcmin.
In the NGC 0274-0275 Group.

4. 1963MCG3..C...0000V
Re:MCG -01-03-021
Interacting pair (with MCG -01-03-022) with bridges, one of which appears
from the arm of MCG -01-03-022. Pair in contact. {rho} = 0.7 arcmin. This
is Holmberg double No. 26. According to another estimate, both components
are 13.3 mag. Photo: VV Atlas No. 81. Type: vB - E1. According to HA 88,
13.0 mag.
