Abstract:
The current paradigm of cosmic formation and evolution of galaxy
clusters foresees growth mostly through merging. Galaxies in the
infall region or in the core of a cluster undergo transformations
owing to different environmental stresses.
For two X-ray luminous clusters at redshift z∼0.3 with opposite
X-ray morphologies (i.e., dynamical states), RXCJ0014.3-3022 and
RXCJ2308.3-0211, we assess differences in galaxy populations as a
function of cluster topography. This is a pilot study for the joint
X-ray and optical analysis of the REFLEX-DXL cluster sample.
Description:
The tables present photometric and spectroscopic data for several
hundreds of galaxies observed in the directions of the galaxy clusters
RXCJ0014.3-3022 (Abell 2744) and RXCJ2308.3-0211 (Abell 2537).
For each galaxy, equatorial coordinates, redshift, equivalent width
measurements and errors for the spectral features [OII], 4000Å
break and Hdelta, total magnitudes and errors in the BVR bands are
given.
The data were acquired with VLT-VIMOS with LR-Blue grism
(spectroscopy) and with B, V and R filters (photometry).
