9 note(s) found in NED.

Re:NGC 4342
NGC 4342 - The mass of the central SMBH measured by Cretton & van den
Bosch (1999) makes this object a outlier for the M_bh_-L relation
(Marconi & Hunt 2003) and the M_bh_-M_b_ relation (Haring & Rix 2004).
According to the analysis of Valluri, Merritt & Emsellem (2004), no
best-fitting value of M_bh_ can be found for this object, the published
value 3.0^+1.7^_-1.0_ x 10^8^ M_sun_ is probably overestimated.

Re:NGC 4342
NGC 4342.
Both the velocity dispersion and the black hole mass are from
Cretton & van den Bosch (1999).

NGC 4342 is in the W Cloud region of the
Virgo Cluster Catalog (Binggeli, Sandage, and
Tammann 1985) in the immediate neighborhood
of the other bright galaxies NGC 4343, IC 3259,
NGC 4341 (=IC 3260), and IC 3267. A number
of dE dwarf ellipticals exist in the field. (It was
understood by Hubble, according to a notation
on the plate envelope of a Mount Wilson 100-inch
plate taken in 1946, that these images are
of "possible dwarfs." Hence, Hubble knew
already in 1946 that dwarf galaxies existed and
presumably, therefore, that a very faint end of
the luminosity function existed, now known as
the Abell-Reaves exponential tail.)
The morphological type of NGC 4342 is
listed in the RSA2 as E7. The type given in the
Virgo Cluster Catalog is S0_1_, suggesting again
that pure E7 galaxies may not exist. No evident
S0 disk is visible on the print here, but it is clear
from the original plates that the isophotes on the
major axis are pointed and are not pure ellipses.

Re:NGC 4342
NGC 4342 (IC 3256)
This highly elongated galaxy resembles an S0 more than an elliptical
galaxy. It is classified E7 in the RSA Catalog but S0 in the RC2. Outside
5" the isophotes are extremely disky, and the position angle and
ellipticity are constant. These results are consistent with Nieto et al.
(1991b), but because of their bad seeing (FWHM = 2.07"), they did not
detect the complex isophotal behavior inside ~5". Although no dust or gas
have been detected (Roberts et al. 1991), the HST image clearly shows two
dust patches around 1"-5" (Paper I). The residual image [Fig. 7(d)] shows
a disk in the center of NGC 4342, that is responsible for the rise in
ellipticity and the sudden increase of the cos 4{theta} term at a < 0.8".

Re:NGC 4342
NGC 4342 (or IC 3256): The RSA type is not acceptable. This small
object has all the usual characters of an S0 with the disk embedded in a
spheroidal halo (see graphs in Fig. 2).

Re:IC 3256
= NGC 4342
Note change of identification from RC1 (see P.A.S.P., 79, 627, 1967).
Ap. J., 146, 28, 1966 (listed as NGC 4343).

Re:ARK 361
(= NGC 4342)
Compact elliptical red object.
According to [RC1] this is a lenticular,
but [UGC] classifies it as a spiral
Radial velocity = +613 km/sec.

Re:NGC 4342
= IC 3256
The identifications of NGC 4341, NGC 4342 and NGC 4343 are uncertain.
The identifications shown in [RC1] Figure 8, which differ from the
Heidelberg and the Mt. Wilson identifications have been adopted
in consultation with Dr. Mayall.
Identified as NGC 4343 in Humason et al. (1956).
Very small, extremely bright nucleus in a bright lens: 0.45 arcmin x
0.15 arcmin.
Very small E2 component at 0.5 arcmin.
NGC 4342 in Yerkes 2 list (Morgan, 1959) is said to be the southern most
galaxy in a group of 5; classification therefore applies to NGC 4343
(new identification).
In Morgan (1958) the classification kE1 may apply to IC 3267?
