Abstract:
We present the results of a new spectroscopic and photometric survey
of the hot, binary X-ray cluster A115 at z=0.193, containing a radio
relic. Our analysis is based on new spectroscopic data obtained at the
Telescopio Nazionale Galileo for 115 galaxies and on new photometric
data obtained at the Isaac Newton Telescope in a large field. We
combine galaxy velocity and position information to select 85 galaxies
recognized as cluster members, determine global dynamical properties
and detect substructures.
Description:
Multi-object spectroscopic observations of A115 were carried out at
the TNG telescope in December 2003 during the program of proposal
AOT8/CAT-G6.

Note (1): Notes as follows:
F = non-cluster galaxies
* = highlight the three brightest cluster members:
BCM-A = 3C28 = 21, BCM-B = 54, BCM-C = 104 (corresponding to
Beers et al. 1983ApJ...264..356B 1983ApJ...264..356B, groups) and a fourth bright
cluster member BCM-D = 81 (see text).
Note (2): Spectral classification as follows:
e(a) = galaxies having EW(Hdelta)≥4Å
e(b) = galaxies having EW([OII])≤-40Å (likely starburst galaxies)
EW(Hdelta)<4Å (likely spiral galaxies)
e(c) = galaxies having moderate emission lines and
EW(Hdelta)<4Å (likely spiral galaxies)
k = passive galaxies
a = active galaxies
k+a = galaxies having 4≤EW(Hdelta)≤8Å
a+k = galaxies having EW(Hdelta)>8Å
