Subaru FOCAS Spectroscopic Observations of High-Redshift Supernovae
Tomoki Morokuma, Kouichi Tokita, Christopher Lidman +30
We present spectra of high-redshift supernovae (SNe) that were taken with the Subaru low resolution optical spectrograph, FOCAS. These SNe were found in SN surveys with Suprime-Cam…
HST Discovery of a z = 3.9 Multiply Imaged Galaxy Behind the Complex Cluster Lens WARPS J1415.1+36 at z = 1.026
X. Huang, T. Morokuma, H. K. Fakhouri +27
We report the discovery of a multiply lensed Ly Alpha (Lya) emitter at z = 3.90 behind the massive galaxy cluster WARPS J1415.1+3612 at z = 1.026. Images taken by the Hubble Space…
An Intensive HST Survey for z>1 Supernovae by Targeting Galaxy Clusters
K. S. Dawson, G. Aldering, R. Amanullah +57
We present a new survey strategy to discover and study high redshift Type Ia supernovae (SNe Ia) using the Hubble Space Telescope (HST). By targeting massive galaxy clusters at 0.9…
Constraining dust and color variations of high-z SNe using NICMOS on Hubble Space Telescope
S. Nobili, V. Fadeyev, G. Aldering +24
We present data from the Supernova Cosmology Project for five high redshift Type Ia supernovae (SNe Ia) that were obtained using the NICMOS infrared camera on the Hubble Space Tele…
Galaxy Clusters in Formation: Determining the Age of the Red-Sequence in Optical and X-ray Clusters at z~1 with HST
Benjamin P. Koester, Michael D. Gladders, David G. Gilbank +7
Using deep two-band imaging from the Hubble Space Telescope, we measure the color-magnitude relations (CMR) of E/S0 galaxies in a set of 9 optically-selected clusters principally f…
