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,…
SNe Ia host galaxy properties from Sloan Digital Sky Survey-II spectroscopy
Jonas Johansson, Daniel Thomas, Janine Pforr +7
We study the stellar populations of SNe Ia host galaxies using SDSS-II spectroscopy. We focus on the relationships of SNe Ia properties with stellar velocity dispersion and the ste…
Cosmology with Photometrically-Classified Type Ia Supernovae from the SDSS-II Supernova Survey
Heather Campbell, Chris B. D'Andrea, Robert C. Nichol +25
We present the cosmological analysis of 752 photometrically-classified Type Ia Supernovae (SNe Ia) obtained from the full Sloan Digital Sky Survey II (SDSS-II) Supernova (SN) Surve…
The SDSS Coadd: 275 deg^2 of Deep SDSS Imaging on Stripe 82
James Annis, Marcelle Soares-Santos, Michael A. Strauss +17
We present details of the construction and characterization of the coaddition of the Sloan Digital Sky Survey Stripe 82 \ugriz\ imaging data. This survey consists of 275 deg of…
Photometric Supernova Cosmology with BEAMS and SDSS-II
Renée Hlozek, Martin Kunz, Bruce Bassett +16
Supernova cosmology without spectroscopic confirmation is an exciting new frontier which we address here with the Bayesian Estimation Applied to Multiple Species (BEAMS) algorithm…
Spectroscopic Properties of Star-Forming Host Galaxies and Type Ia Supernova Hubble Residuals in a Nearly Unbiased Sample
Chris B. D'Andrea, Ravi R. Gupta, Masao Sako +13
We examine the correlation between supernova host galaxy properties and their residuals on the Hubble diagram. We use supernovae discovered during the Sloan Digital Sky Survey II -…
