1. 2005MNRAS.360.1201H
Re:NGC 5921
NGC 5921. This galaxy shows a ring-like structure in both the H{alpha} and the
XDSS blue images. The bar is not clearly seen in H{alpha} but many H II regions
lie at the end of the bar. The centre of the galaxy is the host of a strong
velocity gradient well defined in the H{alpha} velocity map. Nevertheless, no
H{alpha} gas is present between the ring-like structure and the centre.

Re:NGC 5921
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."

Re:NGC 5921
NGC 5921.---SB(r)bc: Marginally resolved nucleus embedded in slightly
elliptical bulge. Bulge is threaded by a prominent bar with a P.A.
skewed by ~30deg from the bulge major axis. A sharp inner ring encloses
the bar. The ring is formed by two spiral arms that begin at the bar
ends and nearly close together. Just before the ring would close, the
arms become very open, broad, and diffuse. At the north end of the
bar, the arm becomes brighter as it leaves the ring. The outer arms
are asymmetric, with the west arm being shorter and more open.

Re:NGC 5921
NGC 5921. - We have detected a very weak 0.5 mJy core and some
additional weak extended emission. At 1.49 GHz and 09 resolution,
Condon (1987) measured a 20.8 mJy source with an additional 2.8 mJy
eastern component that we do not detect at 8.4 GHz. All emission must
be of low surface brightness nature.

Re:NGC 5921
The disk is full of H II regions in the two spiral arms that emerge from
the ends of the stellar bar, where many H II regions are clumped. In
total, we detect 166 H II regions. The nucleus is compact, but its
H{alpha} emission seems to connect with the string of H II regions along
the bar.

Re:NGC 5921
NGC 5921. This is another example of an early-type galaxy with some SF in its
bar. Faint HII regions are seen near the southern end of the stellar bar and
also west of the nucleus which shows intense SF activity. A SF enhancement is
observed at both ends of the stellar bar. Pogge (1989) classifies the nucleus
of NGC 5921 as a LINER.

The two inner arms of high surface brightness
and of the grand design type, are beautiful
examples of the NGC 1300 type, springing from
the ends of a well-defined smooth bar within
which are the two characteristic straight dust
lanes on the leading side of the bar. The arms are
very tightly wound, giving the impression of an
inner ring.
The largest of the numerous HII regions
resolve at the 2" level. The redshift of NGC 5921
is v_o = 1428 km/s.

Re:NGC 5921
NGC 5921 is reported as detected in CO( 1-0) in Verter (1985) but we only
have a poor detection.

Re:NGC 5921
Very interesting and typical {phi}-type spiral. Fairly bright nucleus, about
which is an oval 1.8' long, whose longer axis is crossed by a straight lane of
matter; from the ends of this oval spring the two main whorls of the spiral;
other fainter whorls are visible. Diameter about 5'. Reproduced in Publ. Astr.
Soc. Pacfiic, October, 1912. 43 s.n.
