Notes for object NGC 4473

16 note(s) found in NED.

1. 2006MNRAS.369..497K
Re:NGC 4473
This galaxy exhibits a complex morphology in the velocity dispersion map, with a
region of high dispersion along the major axis which widens at larger radii,
which probably corresponds to two counter-rotating stellar discs. The metal line
strength maps are more flattened than the isophotes, indicating a higher
metallicity in the disc(s), while the H{beta} map is rather flat.

Re:NGC 4473
This galaxy also displays scattered traces of emission, mostly from the [O III]
doublet. [N II]+H{alpha} emission was found by Macchetto et al. (1996) but not
by Goudfrooij et al. (1994). The HST unsharp-masked image highlights the
presence of a nuclear disc, already noticed by van den Bosch et al. (1994). No
dust is visible, contrary to the findings of Ferrari et al. (1999) but
consistent with van Dokkum & Franx (1995).

Re:VCC 1231
VCC 1231 (NGC 4473).Rather elongated system; the color image shows no evidence
of dust, however, there is a small (less than 1") thin rectangular feature
crossing the center of the galaxy. This feature is aligned with the major axis
and bluer than the surrounding regions; it is probably responsible for the
negative B4 coefficient in the very innermost region. Further out, the galaxy
becomes disky, and remains so out to about 10". There does not appear to be a
morphologically distinct nucleus.

Re:NGC 4473
Very small edge-on dust and gas disk, but not seen with HST;
prototypical E5 galaxy

5. 2004MNRAS.352..721E
Re:NGC 4473
NGC 4473: The velocity dispersion field exhibits a complex morphology,
with a region of high dispersion along the major axis which widens at
larger radii, and a central drop inside 3 arcsec, not observed in Bender
et al. (1994). The widening in the dispersion map is particularly
significant outside 10 arcsec where the mean velocity is observed to
decrease outwards. This also corresponds to a region of lower h_4_.

Re:NGC 4473
NGC 4473. Although there is no detection of dust seen in optical
absorption for this galaxy (van Dokkum & Franx 1995) we detect extended
MIR emission at 15 micron which could be associated with a smooth dust
component, preventing detection in the optical.

Re:NGC 4473
NGC 4473: This is a highly elongated Virgo elliptical galaxy. Kundu
(1999) reports bimodality from HST data. Our detection of bimodality is
statistically not compelling, but we find similar mean color peaks to those
of Kundu.

8. 1999A&AS..136..269F
Re:NGC 4473
It shows a very small and edge on dust disk which is clearly observed in
the ionized gas isophotal maps.

NGC 4473 has a prototypical ES morphology of moderate
compactness. The galaxy is in the middle of the E morphological box
where the luminosity gradient is moderately shallow, but yet is
compact enough to be far from the E/S0 boundary.

Re:NGC 4473
NGC 4473 is a highly elongated elliptical classified E5 in both the
RSA and the Second Reference Catalogue of Bright Galaxies (de Vaucouleurs
et al. 1976, hereafter referred to as RC2). The ellipticity slowly
increases from 0.36 at a = 15" to 0.5 at a = 0.5"; the position angle
remains fairly constant. These results are consistent with those found by
Bender et al. (1988). The isophotes are disky at all radii. Between 2"
and 4" the higher order terms show small irregularities, that might
indicate dust, although no gas and or dust has been previously detected
(Roberts et al. 1991, and see also Sec. 3.6).

Re:NGC 4473
NGC 4473: A moderately disky elliptical, which show surprisingly
little rotation (see Davies et al. 1983).

12. 1994A&AS..105..341G
Re:NGC 4473
The stellar disk as revealed by CCD surface photometry (Paper I; Bender
et al. 1988) is found to be significantly bluer ({DELTA}(V-I) ~0.12) than
the surrounding regions of the galaxy. No trace of H{alpha}+[NII]

Re:NGC 4473
Disky isophotes (C4 ~ 0.1) out to r = 50".
