11 note(s) found in NED.


1. 2007MNRAS.382.1552L
Re:NGC 0147
NGC 147: No obvious nucleus was found in this galaxy. Of the three prominent
optical sources in the centre of this galaxy sources 1 and 2 are unresolved and
show a stellar spectrum consistent with early F- and G-type stars, respectively.
They would correspond to foreground stars located at a distance of ~2 kpc. The
third bright source corresponds to a globular cluster (Hodge 1976; Da Costa &
Mould 1988; Han et al. 1997).

Re:NGC 0147
NGC 147: NGC 147 was observed for the first time in X-rays using the
ROSAT HRI, and no emission was detected. These observations have also been
reported by (Brandt et al. 1997). They give a 2{sigma} upper limit for the
flux from a point source located in the galaxy of
6 x 10^-14^ erg s^-1^ cm^-2^ in the 0.1-2.5 keV bandpass, which is in
good agreement with the upper limit reported in Table 5.

Re:NGC 0147
NGC 147 is a dwarf elliptical satellite of M31; the WFPC2 data are
from Han et al. (1997). Its RGB extends farther to the red than
IC 1613's because of the higher mean abundance (and/or age) of NGC 147.
Concordantly, the NGC 147 RC lies ~0.1 mag below IC 1613's. The upper
main sequence is unpopulated in NGC 147, a sign that star formation
ended at least ~1 Gyr ago (Han et al. 1997). A BHB population is
prominent in NGC 147, sharing its locus in the Hess diagram with that of
IC 1613. In NGC 147, star formation went nearly to completion early in
its history, enriching subsequent generations of stars, which now
populate the RGB.

Re:NGC 0147
The spectrum was taken across the geometrical center of the galaxy. The
apparent nucleus (Fig. 2) has a pure A-star spectrum and
v_r_~0 km s^-1^ (but we removed a recessional velocity of -160 km s^-1^,
as given by the RC3, in the spectrum shown in Fig. 2). It thus appears
to be a foreground Galactic star; the stellar population of NGC 147 is
old rather than young (Hodge 1989).

The surface brightness of NGC 147, the dwarf elliptical companion
to M31, is very low. There is a bright nucleus, seen as the slightly
fuzzy object immediately above the brightest star in the frame near
the center of the print. A more complete description of the galaxy and
its stellar content is given on panel 16.

The very low surface brightness of NGC 147 is seen in the
positive image on panel 12. The image here shows the resolution into
individual stars. The print is made from a yellow Palomar plate by
Baade.
The galaxy is the prototype of a nucleated dE,N dwarf elliptical
of the type seen throughout the Virgo Cluster (see Sandage and
Binggeli 1984, for an atlas), in the Fornax Cluster (Caldwell and
Bothun 1987; Ferguson 1989), and in many groups of early-type galaxies
(Ferguson and Sandage 1990).
The nucleus is the fuzzy object just [below] the brightest star
near the center of the print. It is fainter than the two probable
globular clusters, identifiable here by their unsharp appearance in
the left part of the print about halfway between the top and the
bottom borders.
The absolute magnitude of NGC 147 is M_B_T_ = -14.4. Galaxies
like NGC 147 would be well visible in the Virgo Cluster survey and are
then, in fact, included in that catalog (Binggeli, Sandage, and
Tammann 1985); see Table I of Sandage and Binggeli (1984).
RR Lyrae variables have been discovered and studied (Saha and
Hoessel 1987). The surface brightness distribution of the global image
has been discussed by Hodge (1963, 1971, 1976).
