Abstract:
We present a catalog of 1921 spectroscopic redshifts measured in the
fields of the massive galaxy clusters MACSJ0416.1-2403 (z=0.397),
MACSJ0717.5+3745 (z=0.546), and MACSJ1149.5+2223 (z=0.544), i.e.,
three of the four clusters selected by Space Telescope Science
Institute as the targets of the Frontier Fields (FFs) initiative for
studies of the distant Universe via gravitational lensing. Compiled in
the course of the Massive Cluster Survey project (MACS) that detected
the FF clusters, this catalog is provided to the community for three
purposes: (1) to allow the identification of cluster members for
studies of the galaxy population of these extreme systems, (2) to
facilitate the removal of unlensed galaxies and thus reduce shear
dilution in weak-lensing analyses, and (3) to improve the calibration
of photometric redshifts based on both ground- and spacebased
observations of the FF clusters.
Description:
MACSJ0416.1-2403 was observed by us on January 20, 2001 with the
multi-object spectrograph (MOS) on the Canada-Hawaii-France Telescope
(CFHT) on Mauna Kea, Hawaii (effective resolution of 12.5Å).
MACSJ0717.5+3745 and MACSJ1149.5+2223 are part of the subsample of
MACS clusters at z>0.5 (Ebeling et al. 2007ApJ...661L..33E 2007ApJ...661L..33E), and were
observed extensively by us, primarily in the context of a study of the
impact of environment on spectral and morphological properties of the
cluster galaxy population (Ma et al. 2008ApJ...684..160M 2008ApJ...684..160M; Ma & Ebeling
2011MNRAS.410.2593M 2011MNRAS.410.2593M). MACSJ0717.5+3745 was observed with
Keck-II/DEIMOS on nine date between 2003 Dec 23 and 2008 Jan 7, with
Keck-I/LRIS on 2000 Nov 20/21 and 2002 Nov 29 and with Gemini/GMOS on
2004 Mar 12 and 17. MACSJ1149.5+2223 was observed with Gemini/GMOS on
2003 May 1 and 2004 Mar 16 and with Keck-II/DEIMOS on 2005 Feb 12,
2006 Apr 30 and 2009 Feb 26.
