Modification to the Luminosity Distance Redshift Relation in Modified Gravity Theories
Éanna É. Flanagan, Eran Rosenthal, Ira M. Wasserman
We derive an expression for the luminosity distance as a function of redshift for a flat Robertson-Walker spacetime perturbed by arbitrary scalar perturbations possibly produced by…
Luminosity distance in "Swiss cheese" cosmology with randomized voids: I. Single void size
R. Ali Vanderveld, Eanna E. Flanagan, Ira Wasserman
Recently there have been suggestions that the Type Ia supernova data can be explained using only general relativity and cold dark matter with no dark energy. In "Swiss cheese" mode…
Spinning down newborn neutron stars: nonlinear development of the r-mode instability
Ruxandra Bondarescu, Saul A. Teukolsky, Ira Wasserman
We model the nonlinear saturation of the r-mode instability via three-mode couplings and the effects of the instability on the spin evolution of young neutron stars. We include one…
Cosmic Strings as the Source of Small-Scale Microwave Background Anisotropy
Levon Pogosian, S. -H. Henry Tye, Ira Wasserman +1
Cosmic string networks generate cosmological perturbations actively throughout the history of the universe. Thus, the string sourced anisotropy of the cosmic microwave background i…
