Abstract:
The mechanisms giving rise to diffuse radio emission in galaxy
clusters, and in particular their connection with cluster mergers, are
still debated.
We aim to obtain new insights into the internal dynamics of the
cluster Abell 1240, which appears to contain two roughly symmetric
radio relics, separated by ∼2h70-1Mpc.
Description:
Our analysis is based mainly on redshift data for 145 galaxies mostly
acquired at the Telescopio Nazionale Galileo and on new photometric
data acquired at the Isaac Newton Telescope. We also use X-ray data
from the Chandra archive and photometric data from the Sloan Digital
Sky Survey (Data Release 7). We combine galaxy velocities and
positions to select 89 cluster galaxies and analyze the internal
dynamics of the Abell 1237 + Abell 1240 cluster complex, Abell 1237
being a close companion of Abell 1240 in its southern direction.
