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…

A metric space for type Ia supernova spectra

Michele Sasdelli, W. Hillebrandt, G. Aldering +43

We develop a new framework for use in exploring Type Ia Supernova (SN Ia) spectra. Combining Principal Component Analysis (PCA) and Partial Least Square analysis (PLS) we are able…

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…

The Vertical Metallicity Gradient of the Milky Way Disk: Transitions in [a/Fe] Populations

Katharine J. Schlesinger, Jennifer A. Johnson, Constance M. Rockosi +10

Using G dwarfs from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) survey, we have determined a vertical metallicity gradient over a large volume of the Mil…

The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Signs of neutrino mass in current cosmological datasets

Florian Beutler, Shun Saito, Joel R. Brownstein +12

We investigate the cosmological implications of the latest growth of structure measurement from the Baryon Oscillation Spectroscopic Survey (BOSS) CMASS Data Release 11 with partic…
