6 note(s) found in NED.


1. 2007MNRAS.376.1073Z
Re:ABELL 0963
Abell 963. This cluster is very well studied at optical wavelengths, and as a
part of a number of X-ray surveys.

2. 2005MNRAS.359..417S
Re:ABELL 0963
A 963 - HO provides a straightforward yet powerful constraint on the
potential of this cluster, enabling the dynamical and spatial parameters
of both the cluster-scale and BCG mass components to be constrained.

3. 2005ApJ...624..606J
Re:ABELL 0963
A963 (z = 0.21): A963 is elliptical and very relaxed looking, with some
possible very small-scale structure in the core. We included the effects of
background noise when calculating the uncertainties in the power ratios of this
cluster.

Re:ABELL 0963
5.13. A963 Lavery & Henry (1998) report a measured velocity dispersion
of 1350^+200^_-150_ km s^-1^ for this cluster. They also find that the
X-ray-emitting gas has an elliptical distribution with position
angle similar to that of the central cD galaxy. The innermost
isodensity contour in the mass map is also aligned along this
axis. There are two arcs on opposite sides of the cD galaxy,
discovered by Lavery & Henry (1988). The relatively short
exposure times for this cluster give a noisier mass map than for
most other clusters. There is a mass peak coincident with the
position of the central cD in the cluster, but the S/N level is
rather low (around 2 {sigma}).

Re:ABELL 0963
A0963. This cluster is known to be a gravitational lens. The radio
sources A0963.2 and A0963.3 may be located in the cluster.

6. 1998MNRAS.301..328R
Re:ABELL 0963
A963: Included as one of the original Butcher-Oemler clusters
(Butcher & Oemler 1984), A963 has a blue fraction of 0.19 at a redshift
of z = 0.206. Lavery & Henry (1988) found that the blue cluster members
showed signs of very recent star formation, and that the incidence of
near neighbours (within 5 arcsec) was significantly higher for the blue
cluster members than for their red counterparts. The inner region of
A963 has two observed gravitational arclets yielding a mass estimate of
6.0 x 10^13^ M_sun_ for the inner 80 kpc. This cluster possesses a
centrally dominant galaxy and is a candidate for a cluster cooling flow
based on the X-ray analysis. It has a notable centroid shift and
elliptical morphology with a north-south elongation.
