Bumpy Black Holes in Alternate Theories of Gravity
Sarah Vigeland, Nicolás Yunes, Leo Stein
We generalize the bumpy black hole framework to allow for alternative theory deformations. We construct two model-independent parametric deviations from the Kerr metric: one built…

Evidence for alignment of the rotation and velocity vectors in pulsars. II. Further data and emission heights
Simon Johnston, M. Kramer, A. Karastergiou +3
We have conducted observations of 22 pulsars at frequencies of 0.7, 1.4 and 3.1 GHz and present their polarization profiles. The observations were carried out for two main purposes…

Evidence for alignment of the rotation and velocity vectors in pulsars
Simon Johnston, G. Hobbs, S. Vigeland +3
We present strong observational evidence for a relationship between the direction of a pulsar's motion and its rotation axis. We show carefully calibrated polarization data for 25…
