Pauli Murray: In & Out of the Pulpit

This keynote address was delivered on August 6, 2018 at Societas Homiletica at Duke University in Durham, North Carolina and explores the relationship between preaching and identity. The lecture introduces Pauli Murray, a local saint whose activism, writings, and ministry challenged the church and broader society. After a detailed introduction, I consider three principal influences on Pauli’s voice: Cornelia Smith Fitzgerald, Langston Hughes, and James H. Cone. Cornelia Smith Fitzgerald, Pauli’s maternal grandmother, provided a lens for thinking about the ethical and spatial contexts in which sermons arise. Langston Hughes, a fêted poet and author, offered literary inspiration and a model for moving among different genres. James Cone, a path-breaking scholar, gave Pauli vital theological footing and a framework for linking preaching, identity, and activism. Overall, I argue that Pauli Murray makes a singular contribution to the study of African American preaching

The Transition Zone in Balmer-Dominated Shocks

We examine the structure of the post-shock region in supernova remnants (SNRs). The ``shock transition zone'' is set up by charge transfer and ionization events between atoms and ions, and has a width $\sim 10^{15}$ cm$^{-2}$ $n^{-1}_0$, where $n_0$ is the total pre-shock density (including both atoms and ions). For Balmer-dominated SNRs with shock velocity $v_s \gtrsim 1000$ km s$^{-1}$, the Rankine-Hugoniot conditions for ion velocity and temperature are obeyed instantly, leaving the full width at half-maximum (FWHM) of the broad H$\alpha$ line versus $v_s$ relation intact. However, the spatial variation in the post-shock densities is relevant to the problem of Ly$\alpha$ resonant scattering in young, core-collapse SNRs. Both two- (pre-shock atoms and ions) and three-component (pre-shock atoms, broad neutrals and ions) models are considered. We compute the spatial emissivities of the broad ($\xi_b$) and narrow ($\xi_n$) H$\alpha$ lines; a calculation of these emissivities in SN 1006 is in general agreement with the computed ones of Raymond et al. (2007). The (dimensionless) spatial shift, $\Theta_{\rm{shift}}$, between the centroids of $\xi_b$ and $\xi_n$ is unique for a given shock velocity and $f_{\rm{ion}}$, the pre-shock ion fraction. Measurements of $\Theta_{\rm{shift}}$ can be used to constrain $n_0$.Comment: 25 pages, 8 figures. Accepted by Astrophysical Journa
