Abstract:
We present the velocity dispersion and dynamical mass estimates for
270 galaxy clusters included in the first Planck Sunyaev-Zeldovich
(SZ) source catalogue, the PSZ1. Part of the results presented here
were achieved during a two-year observational program, the ITP,
developed at the Roque de los Muchachos Observatory (La Palma, Spain).
In the ITP we carried out a systematic optical follow-up campaign of
all the 212 unidentified PSZ1 sources in the northern sky that have a
declination above -15° and are without known counterparts at the
time of the publication of the catalogue. We present for the first
time the velocity dispersion and dynamical mass of 58 of these ITP
PSZ1 clusters, plus 35 newly discovered clusters that are not
associated with the PSZ1 catalogue. Using Sloan Digital Sky Survey
archival data, we extend this sample, including 212 already confirmed
PSZ1 clusters in the northern sky. Using a subset of 207 of these
galaxy clusters, we constrained the MSZ-Mdyn scaling relation,
finding a mass bias of (1-B)=0/83±0.07(stat)±0.02(sys). We show
that this value is consistent with other results in the literature
that were obtained with different methods (X-ray, dynamical masses,
or weak-lensing mass proxies). This result cannot dissolve the tension
between primordial cosmic microwave background anisotropies and
cluster number counts in the {OMEGA}M-σ8 plane.
Description:
This is the third (and last) paper in a series describing the results
of the ITP13 observational program, dedicated to the characterisation
of the PSZ1 sources in the northern sky without known optical
counterparts at the time the catalogue was published. Here we
presented for the first time the velocity dispersion and mass
estimates for 58 clusters in the PSZ1-North sample and for 35 clusters
that are not associated with the PSZ1 sample.
Using SDSS archival data, we also studied 212 clusters with known
counterparts, and we also extracted the velocity dispersion and mass
estimation, using the same method as for the ITP sample. This paper
presents dynamical masses for 270s within the PSZ1-North sample.
