Union3.1: Reducing Systematics in Supernova Cosmology with Self-consistent Measurements of Host Galaxy Properties for 2000 Type Ia Supernovae
Taylor J. Hoyt, David Rubin, Greg Aldering +3
Photometrically derived distances of Type Ia supernovae (SNe Ia) rely on a empirical correction based on host galaxy properties, e.g., global stellar mass. Unbiased cosmo…
The HST See Change Program: I. Survey Design, Pipeline, and Supernova Discoveries
Brian Hayden, David Rubin, Kyle Boone +53
The See Change survey was designed to make cosmological measurements by efficiently discovering high-redshift Type Ia supernovae (SNe Ia) and improving cluster mass measureme…
First Cosmology Results Using Type Ia Supernovae From the Dark Energy Survey: Survey Overview and Supernova Spectroscopy
C. B. D'Andrea, M. Smith, M. Sullivan +108
We present spectroscopy from the first three seasons of the Dark Energy Survey Supernova Program (DES-SN). We describe the supernova spectroscopic program in full: strategy, observ…
First Cosmology Results using Type Ia Supernovae from the Dark Energy Survey: Constraints on Cosmological Parameters
T. M. C. Abbott, S. Allam, P. Andersen +141
We present the first cosmological parameter constraints using measurements of type Ia supernovae (SNe Ia) from the Dark Energy Survey Supernova Program (DES-SN). The analysis uses…
New Science, New Media: An Assessment of the Online Education and Public Outreach Initiatives of The Dark Energy Survey
R. C. Wolf, A. K. Romer, B. Nord +25
As large-scale international collaborations become the standard for astronomy research, a wealth of opportunities have emerged to create innovative education and public outreach (E…
The Discovery of a Gravitationally Lensed Supernova Ia at Redshift 2.22
David Rubin, Brian Hayden, Xiaosheng Huang +32
We present the discovery and measurements of a gravitationally lensed supernova (SN) behind the galaxy cluster MOO J1014+0038. Based on multi-band Hubble Space Telescope and Very L…
Host Galaxy Identification for Supernova Surveys
Ravi R. Gupta, Steve Kuhlmann, Eve Kovacs +57
Host galaxy identification is a crucial step for modern supernova (SN) surveys such as the Dark Energy Survey (DES) and the Large Synoptic Survey Telescope (LSST), which will disco…
SDSS-II Supernova Survey: An Analysis of the Largest Sample of Type Ia Supernovae and Correlations with Host-Galaxy Spectral Properties
Rachel C. Wolf, Chris B. D'Andrea, Ravi R. Gupta +13
Using the largest single-survey sample of Type Ia supernovae (SNe Ia) to date, we study the relationship between properties of SNe Ia and those of their host galaxies, focusing pri…
The Core Collapse Supernova Rate from the SDSS-II Supernova Survey
Matt Taylor, David Cinabro, Ben Dilday +8
We use the Sloan Digital Sky Survey II Supernova Survey (SDSS-II SNS) data to measure the volumetric core collapse supernova (CCSN) rate in the redshift range (0.03<z<0.09). Using…
The Data Release of the Sloan Digital Sky Survey-II Supernova Survey
Masao Sako, Bruce Bassett, Andrew C. Becker +46
This paper describes the data release of the Sloan Digital Sky Survey-II (SDSS-II) Supernova Survey conducted between 2005 and 2007. Light curves, spectra, classifications, and anc…
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,…
Properties of type Ia supernovae inside rich galaxy clusters
Henrique S. Xavier, Ravi R. Gupta, Masao Sako +9
We used the GMBCG galaxy cluster catalogue and SDSS-II supernovae data with redshifts measured by the BOSS project to identify 48 SNe Ia residing in rich galaxy clusters and compar…
The Fundamental Metallicity Relation Reduces Type Ia SN Hubble Residuals More Than Host Mass Alone
Brian T. Hayden, Ravi R. Gupta, Peter M. Garnavich +3
Type Ia Supernova Hubble residuals have been shown to correlate with host galaxy mass, imposing a major obstacle for their use in measuring dark energy properties. Here, we calibra…
