Calibrating the Planck Cluster Mass Scale with Cluster Velocity Dispersions
Stefania Amodeo, Simona Mei, Spencer A. Stanford +7
We measure the Planck cluster mass bias using dynamical mass measurements based on velocity dispersions of a subsample of 17 Planck-detected clusters. The velocity dispersions were…
Dissection of Halpha Emitters : Low-z Analogs of z>4 Star-Forming Galaxies
Hyunjin Shim, Ranga-Ram Chary
Strong Halpha Emitters (HAEs) dominate the z~4 Lyman-break galaxy population. We have identified local analogs of these HAEs using the Sloan Digital Sky Survey (SDSS). At z<0.4, on…
AKARI Observation of the North Ecliptic Pole (NEP) Supercluster at z = 0.087: mid-infrared view of transition galaxies
Jongwan Ko, Myungshin Im, Hyung Mok Lee +12
We present the mid-infrared (MIR) properties of galaxies within a supercluster in the North Ecliptic Pole region at z?0.087 observed with the AKARI satellite. We use data from the…
Very Strong Emission-Line Galaxies in the WISP Survey and Implications for High-Redshift Galaxies
H. Atek, B. Siana, C. Scarlata +13
The WFC3 Infrared Spectroscopic Parallel Survey (WISP) uses the Hubble Space Telescope (HST) infrared grism capabilities to obtain slitless spectra of thousands of galaxies over a…
z~4 Halpha Emitters in GOODS : Tracing the Dominant Mode for Growth of Galaxies
Hyunjin Shim, Ranga-Ram Chary, Mark Dickinson +4
We present evidence for unusually strong Halpha emission in galaxies with spectroscopic redshifts in the range of 3.8<z<5.0, over the Great Observatories Origins Deep Survey (GOODS…
Merging Galaxy Cluster Abell 2255 in Mid-Infrared
Hyunjin Shim, Myungshin Im, Hyung Mok Lee +11
We present the mid-infrared (MIR) observation of a nearby galaxy cluster, Abell 2255 by the AKARI space telescope. Using the AKARI's continuous wavelength coverage between 3-24 mic…
The WFC3 Infrared Spectroscopic Parallel (WISP) Survey
H. Atek, M. Malkan, P. McCarthy +12
We present the WFC3 Infrared Spectroscopic Parallel (WISP) Survey. WISP is obtaining slitless, near-infrared grism spectroscopy of ~ 90 independent, high-latitude fields by observi…
Polycyclic aromatic hydrocarbon (PAH) luminous galaxies at z~1
T. Takagi, Y. Ohyama, T. Goto +14
Using an AKARI multi-wavelength mid-infrared (IR) survey, we identify luminous starburst galaxies at z> 0.5 based on the PAH luminosity, and investigate the nature of these PAH-sel…
Global Star Formation Rate Density over 0.7<z<1.9
Hyunjin Shim, James Colbert, Harry Teplitz +4
We determine the global star formation rate density at 0.7<z<1.9 using emission-line selected galaxies identified in Hubble Space Telescope Near Infrared Camera and Multi-Object Sp…
