Massive Cluster Survey
(MACS)
(survey of distant clusters evident in ROSAT X-ray data)
The Massive Cluster Survey (MACS)
is a survey
of distant galaxy clusters found by spotting
cluster-candidates by their tell-tale X-ray emissions of
their intracluster medium within ROSAT All Sky Survey (RASS) data.
The clusters were confirmed and observed using a number of
Mauna Kea Observatories telescopes.
A southern extension to MACS has confirmed and observed some
cluster candidates that are too far south for observation from
Hawaii, using southern-hemisphere telescopes.
The designator SMACS has been used for these.
