Abstract:
The Cluster Lensing And Supernova survey with Hubble (CLASH) is a
524-orbit Multi-Cycle Treasury Program to use the gravitational
lensing properties of 25 galaxy clusters to accurately constrain their
mass distributions. The survey, described in detail in this paper,
will definitively establish the degree of concentration of dark matter
in the cluster cores, a key prediction of structure formation models.
The CLASH cluster sample is larger and less biased than current
samples of space-based imaging studies of clusters to similar depth,
as we have minimized lensing-based selection that favors systems with
overly dense cores. Specifically, 20 CLASH clusters are solely X-ray
selected. The X-ray-selected clusters are massive (kT>5keV) and, in
most cases, dynamically relaxed. Five additional clusters are included
for their lensing strength (θEin>35" at zs=2) to optimize
the likelihood of finding highly magnified high-z (z>7) galaxies. A
total of 16 broadband filters, spanning the near-UV to near-IR, are
employed for each 20-orbit campaign on each cluster. These data are
used to measure precise (σz∼0.02(1+z)) photometric redshifts
for newly discovered arcs. Observations of each cluster are spread
over eight epochs to enable a search for Type Ia supernovae at z>1 to
improve constraints on the time dependence of the dark energy equation
of state and the evolution of supernovae. We present newly re-derived
X-ray luminosities, temperatures, and Fe abundances for the CLASH
clusters as well as a representative source list for MACS1149.6+2223
(z=0.544).
Description:
During the CLASH (Cluster Lensing And Supernova survey with Hubble)
program, MACS1149.6+2223 has been imaged in 17 passbands (ACS F555W
comes from archive) using HST WFC3/UVIS, WFC3/IR, and ACS/WFC,
within the program 12068, cycle 18. SExtractor segmentation map for
the central region of the cluster MACS1149.6+2223 is given in
Figure 15.
