Re:NGC 2090
NGC 2090 (Fig. 16.40).-Our GALEX imaging of this isolated SA:(rs)b galaxy
reveals a LSB outer disk barely detected in DSS2-red plates and not at all in
the NIR (2MASS-K_S_ ), but prominent at UV wavelengths. This object is a
prototypical example of a disk in formation at the present epoch. The GALEX data
show a redder inner disk, surrounded by a much bluer, flocculent outer region
characterized by discontinuous spiral segments. H II regions are found in the
Type 2 XUV-disk of NGC 2090 (Koopmann & Kenney 2006). In the bright inner part
of the galaxy, some of these H II regions (and associated UV emission) take the
form of a ring structure.

Re:NGC 2090
NGC 2090.---Sb (type example---see Fig. 3e): Centrally condensed
bulge, with no evidence of a bar. Two-armed, grand-design spiral. Arms
are well defined and wrap more than 360deg before fading. Outer arms
become patchy. Only a few knots in the inner arms.

The distance to NGC 2090 is evidently
smaller than the distance to the Virgo Cluster
(adopted here to be m - M = 31.7) because the
outer arms are well resolved into individual
brightest-star candidates and HII regions. The
largest of the HII regions are resolved into disks
(core + halo) at the 4" level.
Although the resolution into individual
brightest stars is better than in Virgo Cluster
spirals, the galaxy is not as easily resolved as
M101, whose distance modulus, determined from
Cepheids, is m - M = 29.3. An estimate of the
distance modulus of NGC 2090 at about m - M = 31
comes from the ease of resolution into stars.
The redshift is v_o = 755 km/s.
The arm pattern in NGC 2090 is multiple.
The inner region of the disk is covered with spiral
arms that have very high surface brightness. The
outer-arm pattern is composed of arm fragments
of low surface brightness; the resolution into
stars and HII regions is easiest here.

NGC 2090 is repeated here from panel 250
to illustrate and compare the pattern of
high-surface-brightness inner arms and
low-surface-brightness outer arms with the similar
pattern shown by other galaxies on this page. The
pattern is similar to that in such prototype cases as
NGC 1068 (Sb; panel 138) and NGC 3981 (Sbc; panel 178).
The redshift is v_o = 755 km/s.

Re:NGC 2090
Small, bright, diffuse nucleus
in bright lens: 1.65 arcmin x 0.6 arcmin
with several knotty arms and dark lanes,
Poorly resolved, very faint knotty outer arms.
