Confirmation of a Star Formation Bias in Type Ia Supernova Distances and its Effect on Measurement of the Hubble Constant

M. Rigault, G. Aldering, M. Kowalski +35

Previously we used the Nearby Supernova Factory sample to show that SNe~Ia having locally star-forming environments are dimmer than SNe~Ia having locally passive environments.Here…

Type Ia Supernova Distance Modulus Bias and Dispersion From K-correction Errors: A Direct Measurement Using Lightcurve Fits to Observed Spectral Time Series

C. Saunders, G. Aldering, P. Antilogus +34

We estimate systematic errors due to K-corrections in standard photometric analyses of high redshift Type Ia supernovae. Errors due to K-correction occur when the spectral template…

Cosmological implications of baryon acoustic oscillation (BAO) measurements

Éric Aubourg, Stephen Bailey, Julian E. Bautista +90

We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave backgr…

Extending the supernova Hubble diagram to z~1.5 with the Euclid space mission

P. Astier, C. Balland, M. Brescia +25

We forecast dark energy constraints that could be obtained from a new large sample of Type Ia supernovae where those at high redshift are acquired with the Euclid space mission. We…

Particle ejection during mergers of dark matter halos

Isabella P. Carucci, Martin Sparre, Steen H. Hansen +1

Dark matter halos are built from accretion and merging. During merging some of the dark matter particles may be ejected with velocities higher than the escape velocity. We use both…

Type Ia supernova bolometric light curves and ejected mass estimates from the Nearby Supernova Factory

R. Scalzo, G. Aldering, P. Antilogus +32

We present a sample of normal type Ia supernovae from the Nearby Supernova Factory dataset with spectrophotometry at sufficiently late phases to estimate the ejected mass using the…

The Type Ia supernovae rate with Subaru/XMM-Newton Deep Survey

Jun E. Okumura, Yutaka Ihara, Mamoru Doi +15

We present measurements of the rates of high-redshift Type Ia supernovae derived from the Subaru/XMM-Newton Deep Survey (SXDS). We carried out repeat deep imaging observations with…

Type Ia Supernova Hubble Residuals and Host-Galaxy Properties

A. G. Kim, G. Aldering, P. Antilogus +33

Kim et al. (2013) [K13] introduced a new methodology for determining peak-brightness absolute magnitudes of type Ia supernovae from multi-band light curves. We examine the relation…

Cosmological Parameter Uncertainties from SALT-II Type Ia Supernova Light Curve Models

J. Mosher, J. Guy, R. Kessler +11

We use simulated SN Ia samples, including both photometry and spectra, to perform the first direct validation of cosmology analysis using the SALT-II light curve model. This valida…

Improved cosmological constraints from a joint analysis of the SDSS-II and SNLS supernova samples

M. Betoule, R. Kessler, J. Guy +60

We present cosmological constraints from a joint analysis of type Ia supernova (SN Ia) observations obtained by the SDSS-II and SNLS collaborations. The data set includes several l…
