Improved cosmological constraints from new, old, and combined supernova data sets (2008)
Kowalski, M., Rubin, D., Aldering, G., Agostinho, R. J., Amadon, A., Amanullah, R., ...
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 compilations. This...

Measuring Type Ia Supernova Distances and Redshifts From Their Multi-band Light Curves (2007)
The distance and redshift of a type Ia supernova can be determined simultaneously through its multi-band light curves. This fact may be used for imaging surveys that discover and obtain photometry...

Snapping Supernovae at z>1.7 (2006)
Aldering, Greg, Kim, Alex G., Kowalski, Marek, Linder, Eric V., Perlmutter, Saul
We examine the utility of very high redshift Type Ia supernovae for cosmology and systematic uncertainty control. Next generation space surveys such as the Supernova/Acceleration Probe (SNAP) will...
Spectral diversity of Type Ia Supernovae (2006)
James, J. Berian, Davis, Tamara M., Schmidt, Brian P., Kim, Alex G.
We use published spectroscopic and photometric data for 8 Type Ia supernovae to construct a dispersion spectrum for this class of object, showing their diversity over the wavelength range 3700A to...
Ideal bandpasses for type Ia supernova cosmology (2006)
Davis, Tamara M., Schmidt, Brian P., Kim, Alex G.
To use Type Ia supernovae as standard candles for cosmology, we need accurate broadband magnitudes. In practice the observed magnitude may differ from the ideal magnitude‐redshift relationship...

Effects of Systematic Uncertainties on the Supernova Determination of Cosmological Parameters (2003)
Kim, Alex G., Linder, Eric V., Miquel, Ramon, Mostek, Nick
Mapping the recent expansion history of the universe offers the best hope for uncovering the characteristics of the dark energy believed to be responsible for the acceleration of the expansion. In...
Wide-field surveys from the SNAP mission (2002)
Kim, Alex G., Akerlof, C.W., Aldering, G., Amanullah, R., Astier, P., Barrelet, E., ...
Perlmutter, Saul, Gabi, S., Goldhaber, G., Goobar, Ariel, Groom, Donald E., Hook, Isobel, ...
We have developed a technique to systematically discover and study high-redshift supernovae that can be used to measure the cosmological parameters. We report here results based on the initial seven...
Kim, Alex G., Gabi, S., Goldhaber, G., Groom, Donald E., Hook, Isobel, Kim, Min Kook, ...
The Supernova Cosmology Project has discovered over 28 supernovae (SNs) at 0.35 < z < 0.65 in an ongoing program that uses Type Ia SNs (SN Ia's) as high-redshift distance indicators. Here we...

The type Ia supernova rate at z similar to 0.4 (1996)
Pain, Reynald, Hook, Isobel, Deustua, Susana E., Gabi, S., Goldhaber, G., Groom, Donald E., ...
We present the first measurement of the rate of Type la supernovae at high redshift. The result is derived by using a large subset of data from the Supernova Cosmology Project. Three supernovae were...
