Galaxy kinematics across different environments in the RXJ1347-1145
  cluster complex
  In order to understand the role of the different processes that drive galaxy
evolution in clusters, we need comprehensive studies that simultaneously
examine several of the most important characteristics of galaxies. In this work
we examine the physical properties of cluster galaxies at z=0.45 attending to
the degree of distortion of their rotation curves. Regular rotating galaxies
were included in our Tully-Fisher analysis while the distorted ones were used
to study the role of cluster-specific interactions with respect to star
formation and AGN activity. We report a higher fraction of galaxies with
irregular gas kinematics in the cluster environment than in the field. Cluster
galaxies with regular rotation display a moderate brightening in the B-band
Tully-Fisher relation compatible with the gradual evolution of the stellar
populations with lookback time, and no significant evolution in the
stellar-mass Tully-Fisher relation, in line with previous studies at similar
redshift. Average specific star formation rate (sSFR) values are slightly lower
in our cluster sample (-0.15 dex) with respect to the main sequence of
star-forming galaxies, confirming the role of the environment in the early
quenching of star formation in clusters. Finally, we carried out an exploratory
observational study on the stellar-to-halo mass relation finding that cluster
galaxies tend to have slightly lower stellar mass values for a fixed halo mass
compared to their field counterparts.
