Modeling the local velocity field with SNIa
We apply statistically rigorous methods of nonparametric risk estimation to the problem of inferring the local peculiar velocity field from nearby Type Ia supernovae (SNIa). We... -
Intrinsic SN Ia light curves
We have constructed a comprehensive statistical model for Type Ia supernova (SN Ia) light curves spanning optical through near-infrared (NIR) data. A hierarchical framework... -
Production of the p-process nuclei in SNe Ia
We calculate the nucleosynthesis of proton-rich isotopes in the carbon-deflagration model for Type Ia supernovae (SNe Ia). The seed abundances are obtained by calculating the... -
IfA Deep SN rates
The IfA Deep Survey uncovered ~130 thermonuclear supernova (TN SN, i.e., Type Ia) candidates at redshifts from z=0.1 out to beyond z=1. The TN SN explosion rates derived from... -
Host galaxies of SNe Ia in SDSS-II SN survey
We present an analysis of the host galaxy dependences of Type Ia Supernovae (SNe Ia) from the full three year sample of the SDSS-II Supernova Survey. We re-discover, to high... -
Absolute UV magnitudes of type Ia SNe
We examine the absolute magnitudes and light-curve shapes of 14 nearby (redshift z=0.004-0.027) Type Ia supernovae (SNe Ia) observed in the ultraviolet (UV) with the Swift... -
Type Ibc SNe in disturbed galaxies
We compare the radial locations of 178 core-collapse supernovae (CCSNe) to the R-band and H{alpha} light distributions of their host galaxies. When the galaxies are split into... -
HST light curves of six SNe and Union2
We report on work to increase the number of well-measured Type Ia supernovae (SNe Ia) at high redshifts. Light curves, including high signal-to-noise Hubble Space Telescope... -
Linearity of the cosmic expansion field
Particularly accurate relative distances are compiled and homogenized for (1) 246 Type Ia supernovae and 35 clusters with v<30000km/s, and (2) relatively nearby galaxies with... -
SN Ia rate at redshift <~0.3 from SDSS-II
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... -
SDSS-II SN Survey: SNe II-P standardization
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,... -
Local hosts of SNe Ia
We use multi-wavelength, matched aperture, integrated photometry from the Galaxy Evolution Explorer (GALEX), the Sloan Digital Sky Survey, and the RC3 to estimate the physical... -
Swift/UVOT panchromatic observations of SN 2008D
We present extensive early photometric (ultraviolet through near-infrared) and spectroscopic (optical and near-infrared) data on supernova (SN) 2008D as well as X-ray data... -
Light curve parameters of SN Ia
We combine the CfA3 supernovae Type Ia (SN Ia) sample with samples from the literature to calculate improved constraints on the dark energy equation of state parameter, w. The... -
Spectral parameters of SNe Ia
We study the observables of 158 relatively normal Type Ia supernovae (SNe Ia) by dividing them into two groups in terms of the expansion velocity inferred from the absorption... -
Photometry of SN 2008D
On 2008 January 9.56 UT, SN 2008D was discovered while following up an unusually bright X-ray transient (XT) in the nearby spiral galaxy NGC 2770. We present early optical... -
Spectra of unusual optical transient SCP 06F6
We present observations of SCP 06F6, an unusual optical transient discovered during the Hubble Space Telescope Cluster Supernova Survey. The transient brightened over a period... -
SNe Ia as NIR standard candles from PAIRITEL
We have obtained 1087 NIR (JHK_s_) measurements of 21 SNe Ia using PAIRITEL, nearly doubling the number of well-sampled NIR SN Ia light curves. These data strengthen the... -
Improved cosmological constraints from SNe
We present a new compilation of Type Ia supernovae (SNe Ia), a new data set of low-redshift nearby-Hubble-flow SNe, and new analysis procedures to work with these heterogeneous... -
Neutrino cross sections for SNe
The neutrino-nucleus reaction cross sections of ^4^He and ^12^C are evaluated using new shell model Hamiltonians. Branching ratios of various decay channels are calculated to...
