Abstract:
We use dense redshift surveys of nine galaxy clusters at z∼0.2 to
compare the galaxy distribution in each system with the projected
matter distribution from weak lensing. By combining 2087 new
MMT/Hectospec redshifts and the data in the literature, we construct
spectroscopic samples within the region of weak-lensing maps of high
(70%-89%) and uniform completeness.
Description:
Among the 30 clusters at z ∼ 0.2 with Subaru weak-lensing maps in
Okabe et al. (2010PASJ...62..811O 2010PASJ...62..811O), we first select five clusters with
dense redshift data in the Hectospec Cluster Survey (HeCS; Rines et
al. 2013, J/ApJ/767/15). We supplement these data with redshifts from
the literature (Girardi et al. 2006, J/A+A/455/45; Drinkwater et al.
2010, J/MNRAS/401/1429; Owers et al. 2011, J/ApJ/741/122; Lemze et al.
2013, J/ApJ/776/91; Jaffe et al. 2013, J/MNRAS/431/2111; Geller et al.
2014ApJ...783...52G 2014ApJ...783...52G), the Sloan Digital Sky Survey data release 10
(SDSS DR10; Ahn et al. 2014ApJS..211...17A 2014ApJS..211...17A), and the NASA/IPAC
Extragalactic Database (NED).
We made additional observations of four HeCS clusters (A689, A697,
A750, and A963) in 2013 February and March with the 300 fiber
Hectospec on the MMT 6.5m telescope (Fabricant et al.
2005PASP..117.1411F 2005PASP..117.1411F). The four clusters are within the footprint of
the SDSS DR10.
