The Sloan Digital Sky Survey-II (SDSS-II) has embarked on a multi-year project to identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae (SNe Ia) using repeated five-band (ugriz) imaging over an area of 300 s...

New Dynamical Window onto the Landscape for Forced Protein Unfolding (2008)
Journal Article
Yew, Z., McLeish, T., & Paci, E. (2008). New Dynamical Window onto the Landscape for Forced Protein Unfolding. Physical Review Letters, 101(24), Article 248104. https://doi.org/10.1103/physrevlett.101.248104

The unfolding of a protein by the application of an external force pulling two atoms of the protein can be detected by atomic force and optical tweezers technologies as have been broadly demonstrated in the past decade. Variation of the applied force... Read More about New Dynamical Window onto the Landscape for Forced Protein Unfolding.

Virial Scaling of Massive Dark Matter Halos: Why Clusters Prefer a High Normalization Cosmology (2008)
Journal Article
Evrard, A., Bialek, J., Busha, M., White, M., Habib, S., Heitmann, K., …Diemand, J. (2008). Virial Scaling of Massive Dark Matter Halos: Why Clusters Prefer a High Normalization Cosmology. Astrophysical Journal, 672(1), 122-137. https://doi.org/10.1086/521616

We present a precise estimate of the bulk virial scaling relation of halos formed via hierarchical clustering in an ensemble of simulated cold dark matter cosmologies. The result is insensitive to cosmological parameters; the presence of a trace, dis... Read More about Virial Scaling of Massive Dark Matter Halos: Why Clusters Prefer a High Normalization Cosmology.

Weak-lensing ellipticities in a strong-lensing regime (2008)
Journal Article
Massey, R., & Goldberg, D. (2008). Weak-lensing ellipticities in a strong-lensing regime. Astrophysical Journal Letters, 673(2), L111-L114. https://doi.org/10.1086/528791

It is now routine to measure the weak gravitational lensing shear signal from the mean ellipticity of distant galaxies. However, conversion between ellipticity and shear assumes local linearity of the lensing potential (i.e., that the spatial derivat...
