With a joint Subaru+HST weak gravitational lensing analysis, we identify two dominant subclusters and estimate the masses to be M_200_=5.7_-1.8_^+2.8^x10^14^M_{sun}_ and 1.2_-0.6_^+1.4^x10^14^M_{sun}_. We estimate the projected separation between the two subclusters to be 924_-206_^+243^kpc. We perform a clustering analysis of spectroscopically confirmed cluster member galaxies and estimate the line-of-sight velocity difference between the two subclusters to be 92+/-164km/s. We further motivate, discuss, and analyze the merger scenario through an analysis of the 42ks of Chandra/ACIS-I and JVLA/C and D array polarization data. The X-ray surface brightness profile reveals a merging gas-core reminiscent of the Bullet Cluster. The global X-ray luminosity in the 0.5-7.0keV band is 1.7+/-0.1x10^44^erg/s and the global X-ray temperature is 4.90+/-0.13keV. The radio relics are polarized up to 40% , and along with the masses, velocities, and positions of the two subclusters, we input these quantities into a Monte Carlo dynamical analysis and estimate the merger velocity at pericenter to be 1800_-300_^+400^km/s. This is a lower-mass version of the Bullet Cluster and therefore may prove useful in testing alternative models of dark matter (DM). We do not find significant offsets between DM and galaxies, but the uncertainties are large with the current lensing data. Furthermore, in the east, the BCG is offset from other luminous cluster galaxies, which poses a puzzle for defining DM-galaxy offsets.2017ApJ...838..110Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/838/110CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)B/chandra : The Chandra Archive Log (CXC, 1999-2014)II/261 : GOODS initial results (Giavalisco+, 2004)VIII/76 : Leiden/Argentine/Bonn (LAB) Survey of Galactic HI (Kalberla+ 2005)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/ApJ/702/1230 : Rotation measure image of the sky (Taylor+, 2009)J/A+A/549/A8 : Atm. extinction properties above Mauna Kea (Buton+, 2013)J/ApJ/772/131 : Musket Ball Cluster redshift catalog (Dawson, 2013)J/A+A/580/A95 : Planck/AMI Sunyaev-Zel'dovich measurements (Perrott+, 2015)J/ApJ/805/143 : MC2: redshift analysis of CIZA J2242.8+5301 (Dawson+, 2015)J/MNRAS/450/630 : MC2: SFR in CIZA J2242.8+5301 (Sobral+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/838/110https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/838/110http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/838/110https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/838/110https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/838/110http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/838/110GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/838/110/table2 (High quality DEIMOS galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/838/110/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/838/110/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/838/110/table2?GETtext/xml+votable180.050000true2.840446152.528860.0055555555555555566/28132.8629656356604037e-19 3.5857638086678825e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/838/110?format=asciiOpticalInfrareddefaultJ/ApJ/838/110/table2High quality DEIMOS galaxiesrecnoRecord number assigned by the VizieR team.
