Abstract:
We present a catalogue of galaxy clusters detected in the Planck
all-sky Compton parameter maps and identified using data from the WISE
and SDSS surveys. The catalogue comprises about 3000 clusters in the
SDSS fields. We expect the completeness of this catalogue to be high
for clusters with masses larger than M500~=3x1014M☉, located
at redshifts z<0.7. At redshifts above z~=0.4, the catalogue contains
approximately an order of magnitude more clusters than the 2nd Planck
Catalogue of Sunyaev-Zeldovich sources in the same fields of the sky.
This catalogue can be used for identification of massive galaxy
clusters in future large cluster surveys, such as the SRG/eROSITA
all-sky X-ray survey.
Description:
We present a catalogue of galaxy clusters detected in Planck
all-skyCompton parameter maps and identified using data from the WISE
and SDSS surveys. Our catalogue comprises about 3000 clusters found in
the SDSS fields, with masses higher than approximately
M500∼3x104M☉. At redshifts above z>0.4, the catalogue
contains approximately an order of magnitude more clusters than the
2nd Planck Catalogue of Sunyaev-Zeldovich sources in the same fields
of the sky.
