Three Gravitationally Lensed Supernovae Behind CLASH Galaxy Clusters
Brandon Patel, Curtis McCully, Saurabh W. Jha +42
We report observations of three gravitationally lensed supernovae (SNe) in the Cluster Lensing And Supernova survey with Hubble (CLASH) Multi-Cycle Treasury program. These objects,…
Type-Ia Supernova Rates to Redshift 2.4 from CLASH: the Cluster Lensing And Supernova survey with Hubble
O. Graur, S. A. Rodney, D. Maoz +38
We present the supernova (SN) sample and Type-Ia SN (SN Ia) rates from the Cluster Lensing And Supernova survey with Hubble (CLASH). Using the Advanced Camera for Surveys and the W…
SweetSpot: Near-Infrared Observations of Thirteen Type Ia Supernovae from a New NOAO Survey Probing the Nearby Smooth Hubble Flow
Anja Weyant, W. Michael Wood-Vasey, Lori Allen +4
We present 13 Type Ia supernovae (SNe Ia) observed in the restframe near-infrared (NIR) from 0.02 < z < 0.09 with the WIYN High-resolution Infrared Camera (WHIRC) on the WIYN 3.5-m…
Hubble Space Telescope and Ground-Based Observations of the Type Iax Supernovae SN 2005hk and SN 2008A
Curtis McCully, Saurabh W. Jha, Ryan J. Foley +24
We present Hubble Space Telescope (HST) and ground-based optical and near-infrared observations of SN 2005hk and SN 2008A, typical members of the Type Iax class of supernovae (SNe)…
Host Galaxy Spectra and Consequences for SN Typing From The SDSS SN Survey
Matthew D. Olmstead, Peter J. Brown, Masao Sako +28
We present the spectroscopy from 5254 galaxies that hosted supernovae (SNe) or other transient events in the Sloan Digital Sky Survey II (SDSS-II). Obtained during SDSS-I, SDSS-II,…
The Effect of Weak Lensing on Distance Estimates from Supernovae
Mathew Smith, David J. Bacon, Robert C. Nichol +14
Using a sample of 608 Type Ia supernovae from the SDSS-II and BOSS surveys, combined with a sample of foreground galaxies from SDSS-II, we estimate the weak lensing convergence for…
