ZFIRE: Galaxy Cluster Kinematics, H Star Formation Rates, and Gas-Phase Metallicities of XMM-LSS J02182-05102 at z=1.6233

Kim-Vy H. Tran, Themiya Nanayakkara, Tiantian Yuan +11

We spectroscopically survey the galaxy cluster XMM-LSS J02182-05102 (hereafter IRC 0218) using LRIS (optical) and MOSFIRE (near-infrared) on Keck I as part of the ZFIRE survey. IRC…

Z-FIRE: ISM properties of the z = 2.095 COSMOS Cluster

Lisa J. Kewley, Tiantian Yuan, Themiya Nanayakkara +9

We investigate the ISM properties of 13 star-forming galaxies within the z~2 COSMOS cluster. We show that the cluster members have [NII]/Ha and [OIII]/Hb emission-line ratios simil…

HII Region Metallicity Constraints Near the Site of the Strongly Lensed Supernova "SN Refsdal" at Redshift 1.49

T. -T. Yuan, C. Kobayashi, L. J. Kewley

We present the local HII region metallicity near the site of the recently discovered multiply lensed supernova (SN; "SN Refsdal") at redshift 1.49. "SN Refsdal" is located at the o…

The Absence of an Environmental Dependence in the Mass-Metallicity Relation at z=2

Glenn G. Kacprzak, Tiantian Yuan, Themiya Nanayakkara +10

We investigate the environmental dependence of the mass-metallicity relation at z=2 with MOSFIRE/Keck as part of the ZFIRE survey. Here, we present the chemical abundance of a Virg…

Kinematic classifications of local interacting galaxies: implications for the merger/disk classifications at high-z

Chao-Ling Hung, Jeffrey A. Rich, Tiantian Yuan +6

The classification of galaxy mergers and isolated disks is key for understanding the relative importance of galaxy interactions and secular evolution during the assembly of galaxie…
