Abstract:
A robust determination of galaxy cluster mass is crucial to use them
as cosmological probes, or to study the physics governing their
formation and evolution. Applying various estimators on well-defined
cluster samples is a mandatory step in characterising their respective
systematics.
Our main goal is to compare the results of three dynamical mass
estimators to the X-ray hydrostatic values. Here we focus on massive
galaxy clusters at intermediate redshifts z∼0.3.
We estimated dynamical masses with the virial theorem, the Jeans
equation, and the caustic method using wide-field VIMOS spectroscopy;
the hydrostatic masses were obtained previously from XMM-Newton
observations.We investigated the role of colour selection and the
impact of substructures on the dynamical estimators.
Description:
Photometric and spectroscopic redshifts of the cluster members for
RXCJ0014.3-3023, RXCJ0225.9-4154, RXCJ0516.6-5430, RXCJ0528.9-3927,
RXCJ0658.5-5556, RXCJ1131.9-1955, RXCJ1206.2-0848, RXCJ1347.5-114,
RXCJ2011.3-5725, and RXCJ2308.3-2011. When a spectroscopic redshift is
available, the photometric value is the same. In addition, we provide
a quality flag for the spectroscopic redshift (except for redshifts
taken from the literature) and an uncertainty on the photometric
estimate. We also provide a red-sequence membership flag.
Spectroscopic redshifts have a typical uncertainty of 250-300km/s.
