East End Eden: The Gentrification of Portland’s Munjoy Hill

Date: 2024-01-01

Creator: Katharine Kurtz

Access: Open access

This thesis explores the gentrification of Munjoy Hill, a neighborhood on the northeast end of Portland, Maine from 1990-2024. Once the industrial hub of the city filled with factories and an industrial shipping port in the late 1800s and early 1900s, Munjoy Hill is now the most desirable neighborhood in the city with expensive, high-end condos, water views, ocean access, and hip restaurants and breweries. I argue that Munjoy Hill’s industrial past and strong connection to the local environment has made it unique, however the recent gentrification also makes Munjoy Hill a place that resembles, gentrified neighborhoods in cities around the country. This thesis studies Munjoy Hill’s change through three lenses: environment, housing, and food and drink. In the environment chapter I argue that the Hill’s natural beauty and connection to Maine’s scenic coastline primed it for gentrification once the area deindustrialized in the 1990s. In the housing chapter I explore the dramatic increase in housing prices and three ways residents are attempting to control the changes: affordable housing development, zoning, and historic designation. In my final chapter I analyze the role of new food establishments in transforming the Hill’s culture and cementing it as a neighborhood that feels, in part, like gentrified neighborhoods around the country.


Accretion onto endoparasitic black holes at the center of neutron stars

Access: Open access

We revisit the system consisting of a neutron star that harbors a small, possibly primordial, black hole at its center, focusing on a nonspinning black hole embedded in a nonrotating neutron star. Extending earlier treatments, we provide an analytical treatment describing the rate of secular accretion of the neutron star matter onto the black hole, adopting the relativistic Bondi accretion formalism for stiff equations of state that we presented elsewhere. We use these accretion rates to sketch the evolution of the system analytically until the neutron star is completely consumed. We also perform numerical simulations in full general relativity for black holes with masses up to nine orders of magnitude smaller than the neutron star mass, including a simulation of the entire evolution through collapse for the largest black hole mass. We construct relativistic initial data for these simulations by generalizing the black hole puncture method to allow for the presence of matter, and evolve these data with a code that is optimally designed to resolve the vastly different length scales present in this problem. We compare our analytic and numerical results, and provide expressions for the lifetime of neutron stars harboring such endoparasitic black holes.
