How well can ultracompact bodies imitate black hole ringdowns?
Kostas Glampedakis, George Pappas
The ongoing observations of merging black holes by the instruments of the fledging gravitational wave astronomy has opened the way for testing the general relativistic Kerr black h…
Universal Relations and Alternative Gravity Theories
Daniela D. Doneva, George Pappas
This is a review with the ambitious goal of covering the recent progress in: 1) universal relations (in general relativity and alternative theories of gravity), and 2) neutron star…
Post-Kerr black hole spectroscopy
Kostas Glampedakis, George Pappas, Hector O. Silva +1
One of the central goals of the newborn field of gravitational wave astronomy is to test gravity in the highly nonlinear, strong field regime characterizing the spacetime of black…
Cup products in the etale cohomology of number fields
Frauke M. Bleher, Ted Chinburg, Ralph Greenberg +3
This paper concerns cup product pairings in étale cohomology related to work of M. Kim and of W. McCallum and R. Sharifi. We will show that by considering Ext groups rather than co…
(G, μ)-displays and Rapoport-Zink spaces
O. Bueltel, G. Pappas
Let (G, μ) be a pair of a reductive group G over the p-adic integers and a minuscule cocharacter μ of G defined over an unramified extension. We introduce and study "(G, μ)-display…
