    The Future of Epistemic Possibility
    Kriterion - Journal of Philosophy 31 (1): 45-62. 2017.
    I am concerned with epistemic possibility expressions (EPEs) such as “It might be raining.” Much of the discussion of EPEs has concerned the fact that a given EPE can seem true in one context and false in another. Motivated by this data, contextualists have argued that modal expressions are sensitive to information at a context of use. Contextualist analyses encounter problems when it comes to disagreements centered on EPEs. Relativists such as John MacFarlane argue that epistemic modals are sen…Read more
  • Spectral models for early time SN 2011fe observations
    with E. Baron, P. Hoeflich, B. Friesen, M. Sullivan, E. Hsiao, R. S. Ellis, A. Gal-Yam, P. E. da HowellNugent, I. Dominguez, K. Krisciunas, N. Suntzeff, L. Wang, and R. C. Thomas
    © 2015 The Authors. Published by Oxford University Press on behalf of the Royal Astronomical Society.We use observedUVthrough near-IR spectra to examine whether SN 2011fe can be understood in the framework of Branch-normal Type Ia supernovae and to examine its individual peculiarities. As a benchmark, we use a delayed-detonationmodel with a progenitormetallicity of Z⊙/20. We study the sensitivity of features to variations in progenitor metallicity, the outer density profile, and the distribution…Read more
