Re:NGC 5665
4.3 NGC 5665 (Arp 49) Although NGC 5665 has a somewhat asymmetric
optical morphology, the peak in the 850 microns emission does agree
with the peak in the R-band optical image, which is also the radio
centre (see Condon 1990). Artamonov, Badan & Gusev (2000) examined the
stellar populations of NGC 5665 using BVRI photometry. They suggested
that NGC 5665 merged with a small companion galaxy 5x10^8^ yr ago,
causing a burst of star formation which was strongest in the
south-eastern part of the disc. This corresponds to the peak in the 850
microns emission. Suprisingly, the H I emission (although having a
somewhat irregular distribution) is not significantly offset from the
optical centre of the galaxy.

NGC 5665 has many HII knots spread over
an interior spiral pattern that, if the form is to
be classified, would be of type Sc. A smooth
continuation of the arm on the left side of the
print suggests a similarity to NGC 4580, shown
at the left, which is the prototype of the Sa/Sc
mixed type.
The galaxy is isolated from any other bright
Dreyer listing. The closest Dreyer galaxy is NGC
5645, which is 50' south and is not a candidate
for any postulated interaction. The form of NGC
5665 appears to be generic, not environmental.

NGC 5665 is also illustrated in the Sa
section (panel 86).
The smooth outer arms are devoid of
star-forming regions but the inner parts of the image
are filled with HII-region candidates. There is no
nucleus or central bulge. There is a thin, single-inner-arm
pattern that can be traced for 1 1/2 revolutions.

Re:VV 412
Asymmetric spiral.
Nucleus is approximately 4 arcsec in diameter.

Re:VV 412
Plate 8 Galaxies of the M51 Type.
MCG +01-37-024 = Arp 049 = NGC 5665; 12.6m. V_0_=+2250(V).
The starlike object is an H II region = companion on the tip of the
spiral arm as shown by its spectrum. {DELTA}V_0_ of the companions
is 60 km s^-1^.
VV 412 and VV 413, where Arp (1970) has shown that the starlike objects
at the tips of the spiral arms are small companions with the spectra
of H II regions, are most important as indicating that these arms could
not be formed tidally.
