The Hubble Space Telescope Cluster Supernova Survey: VI. The Volumetric Type Ia Supernova Rate
K. Barbary, G. Aldering, R. Amanullah +40
We present a measurement of the volumetric Type Ia supernova (SN Ia) rate out to z ~ 1.6 from the Hubble Space Telescope Cluster Supernova Survey. In observations spanning 189 orbi…
Implications for Galaxy Evolution from the Cosmic Evolution of Supernova Rate Density
T. Oda, T. Totani, N. Yasuda +4
We report a comprehensive statistical analysis of the observational data of the cosmic evolution of supernova (SN) rate density, to derive constraints on cosmic star formation hist…
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…
The Hubble Space Telescope Cluster Supernova Survey: III. Correlated Properties of Type Ia Supernovae and Their Hosts at 0.9 < z < 1.46
J. Meyers, G. Aldering, K. Barbary +35
Using the sample of Type Ia supernovae (SNe Ia) discovered by the Hubble Space Telescope (HST) Cluster Supernova Survey and augmented with HST-observed SNe Ia in the GOODS fields,…
Up-Down Quark Mass Difference Effect in Nuclear Many-Body Systems
S. Nakamura, K. Muto, M. Oka +2
A charge-symmetry-breaking nucleon-nucleon force due to the up-down quark mass difference is evaluated in the quark cluster model. It is applied to the shell-model calculation for…
The Hubble Space Telescope Cluster Supernova Survey: V. Improving the Dark Energy Constraints Above z>1 and Building an Early-Type-Hosted Supernova Sample
N. Suzuki, D. Rubin, C. Lidman +62
We present ACS, NICMOS, and Keck AO-assisted photometry of 20 Type Ia supernovae SNe Ia from the HST Cluster Supernova Survey. The SNe Ia were discovered over the redshift interval…
The Hubble Space Telescope Cluster Supernova Survey: II. The Type Ia Supernova Rate in High-Redshift Galaxy Clusters
K. Barbary, G. Aldering, R. Amanullah +40
We report a measurement of the Type Ia supernova (SN Ia) rate in galaxy clusters at 0.9 < z < 1.45 from the Hubble Space Telescope (HST) Cluster Supernova Survey. This is the first…
Pulsed UCN production using a Doppler shifter at J-PARC
S. Imajo, K. Mishima, M. Kitaguchi +8
We have constructed a Doppler-shifter-type pulsed ultra-cold neutron (UCN) source at the Materials and Life Science Experiment Facility (MLF) of the Japan Proton Accelerator Resear…
Development and application of a He Neutron Spin Filter at J-PARC
T. Okudaira, T. Oku, T. Ino +22
We are developing a neutron polarizer with polarized He gas, referred to as a He spin filter, based on the Spin Exchange Optical Pumping (SEOP) for polarized neutron scatte…
