Supernova 2011fe from an Exploding Carbon-Oxygen White Dwarf Star
Peter E. Nugent, Mark Sullivan, S. Bradley Cenko +36
Type Ia supernovae (SNe Ia) have been used empirically as standardized candles to reveal the accelerating universe even though fundamental details, such as the nature of the progen…
SNANA: A Public Software Package for Supernova Analysis
Richard Kessler, Joseph P. Bernstein, David Cinabro +8
We describe a general analysis package for supernova (SN) light curves, called SNANA, that contains a simulation, light curve fitter, and cosmology fitter. The software is designed…
A Measurement of the Rate of Type Ia Supernovae in Galaxy Clusters from the SDSS-II Supernova Survey
Benjamin Dilday, Bruce Bassett, Andrew Becker +32
ABRIDGED We present measurements of the Type Ia supernova (SN) rate in galaxy clusters based on data from the Sloan Digital Sky Survey-II (SDSS-II) Supernova Survey. The cluster SN…
The Rise and Fall of Type Ia Supernova Light Curves in the SDSS-II Supernova Survey
Brian T. Hayden, Peter M. Garnavich, Richard Kessler +13
We analyze the rise and fall times of type Ia supernova (SN Ia) light curves discovered by the SDSS-II Supernova Survey. From a set of 391 light curves k-corrected to the rest fram…
A Measurement of the Rate of type-Ia Supernovae at Redshift 0.1 from the First Season of the SDSS-II Supernova Survey
Benjamin Dilday, R. Kessler, J. A. Frieman +50
We present a measurement of the rate of type Ia supernovae (SNe Ia) from the first of three seasons of data from the SDSS-II Supernova Survey. For this measurement, we include 17 S…
The SDSS-II Supernova Survey: Parameterizing the Type Ia Supernova Rate as a Function of Host Galaxy Properties
Mathew Smith, Robert C Nichol, Benjamin Dilday +11
Using data from the Sloan Digital Sky Supernova Survey-II, we measure the rate of Type Ia Supernovae (SNe Ia) as a function of galaxy properties at intermediate redshift. A sample…
The Effect of Host Galaxies on Type Ia Supernovae in the SDSS-II Supernova Survey
Hubert Lampeitl, Mathew Smith, Robert C. Nichol +18
We present an analysis of the host galaxy dependencies of Type Ia Supernovae (SNe Ia) from the full three year sample of the SDSS-II Supernova Survey. We rediscover, to high signif…
2006 SQ372: A Likely Long-Period Comet from the Inner Oort Cloud
Nathan A. Kaib, Andrew C. Becker, R. Lynne Jones +9
We report the discovery of a minor planet (2006 SQ372) on an orbit with a perihelion of 24 AU and a semimajor axis of 796 AU. Dynamical simulations show that this is a transient or…
Measurements of the Rate of Type Ia Supernovae at Redshift z < ~0.3 from the SDSS-II Supernova Survey
Benjamin Dilday, Mathew Smith, Bruce Bassett +33
We present a measurement of the volumetric Type Ia supernova (SN Ia) rate based on data from the Sloan Digital Sky Survey II (SDSS-II) Supernova Survey. The adopted sample of super…
First-year Sloan Digital Sky Survey-II (SDSS-II) Supernova Results: Hubble Diagram and Cosmological Parameters
Richard Kessler, Andrew Becker, David Cinabro +43
We present measurements of the Hubble diagram for 103 Type Ia supernovae (SNe) with redshifts 0.04 < z < 0.42, discovered during the first season (Fall 2005) of the Sloan Digital S…
Single or Double Degenerate Progenitors? Searching for Shock Emission in the SDSS-II Type Ia Supernovae
Brian T. Hayden, Peter M. Garnavich, Daniel Kasen +10
From the set of nearly 500 spectroscopically confirmed type~Ia supernovae and around 10,000 unconfirmed candidates from SDSS-II, we select a subset of 108 confirmed SNe Ia with wel…
Photometric Estimates of Redshifts and Distance Moduli for Type Ia Supernovae
Richard Kessler, David Cinabro, Bruce Bassett +14
Large planned photometric surveys will discover hundreds of thousands of supernovae (SNe), outstripping the resources available for spectroscopic follow-up and necessitating the de…
Type II-P Supernovae from the SDSS-II Supernova Survey and the Standardized Candle Method
Chris B. D'Andrea, Masao Sako, Benjamin Dilday +24
We apply the Standardized Candle Method (SCM) for Type II Plateau supernovae (SNe II-P), which relates the velocity of the ejecta of a SN to its luminosity during the plateau, to 1…
Distance estimate to NGC 6951 from supernova siblings Type IIP SN 2020dpw and Type Ib SN 2021sjt
Réka Könyves-Tóth, Zsófia Bodola, Tamás Szalai +24
{Supernova (SN) siblings are powerful tools used to calibrate and improve distance measurement methods, and to make the systematic uncertainty to distances to their host galaxies c…
Photometric SN Ia Candidates from the Three-Year SDSS-II SN Survey Data
Masao Sako, Bruce Bassett, Brian Connolly +12
We analyze the three-year SDSS-II Superernova (SN) Survey data and identify a sample of 1070 photometric SN Ia candidates based on their multi-band light curve data. This sample co…
