Abstract:
We present a new method for photometering objects in galaxy clusters.
We introduce a mode-filtering technique for removing spatially
variable backgrounds, improving both detection and photometric
accuracy (roughly halving the scatter in the red sequence compared to
previous catalogs of the same clusters). This method is based on
robustly determining the distribution of background pixel values and
should provide comparable improvement in photometric analysis of any
crowded fields. We produce new multiwavelength catalogs for the 25
CLASH cluster fields in all 16 bandpasses from the UV through the
near-IR, as well as rest-frame magnitudes. A comparison with
spectroscopic values from the literature finds a ∼30% decrease in the
redshift deviation from previously released CLASH photometry. This
improvement in redshift precision, in combination with a detection
scheme designed to maximize purity, yields a substantial upgrade in
cluster member identification over the previous CLASH galaxy catalog.
We construct luminosity functions for each cluster, reliably reaching
depths of at least 4.5mag below M* in every case, and deeper still in
several clusters. We measure M* , α, and their redshift
evolution, assuming the cluster populations are coeval, and find
little to no evolution of α≲-0.9≲α≲-0.8, and M*
values consistent with passive evolution. We present a catalog of
galaxy photometry, photometric and spectroscopic redshifts, and
rest-frame photometry for the full fields of view of all 25 CLASH
clusters. Not only will our new photometric catalogs enable new
studies of the properties of CLASH clusters, but mode-filtering
techniques, such as those presented here, should greatly enhance the
data quality of future photometric surveys of crowded fields.
Description:
Imaging data in this work come from the Cluster Lensing and Supernova
Survey with Hubble (CLASH). This HST Multi-cycle Treasury Program
imaged 25 galaxy cluster in 16 filters, covering the UV to the IR.
