On the Probability of Microlensing in GRB Afterglows
L. V. E. Koopmans, J. Wambsganss
The declining lightcurve of the optical afterglow of gamma-ray burst GRB000301C showed rapid variability with one particularly bright feature at about t-t0=3.8 days. This event was…
On the stability of the Kerr metric
Horst R. Beyer
The reduced (in the angular coordinate ) wave equation and Klein-Gordon equation are considered on a Kerr background and in the framework of -semigroup theory. Each equat…
A framework for perturbations and stability of differentially rotating stars
Horst R. Beyer
The paper provides a new framework for the description of linearized adiabatic lagrangian perturbations and stability of differentially rotating newtonian stars. In doing so it ove…
Effect of a neutron-star crust on the r-mode instability
Lee Lindblom, Benjamin J. Owen, Greg Ushomirsky
The presence of a viscous boundary layer under the solid crust of a neutron star dramatically increases the viscous damping rate of the fluid r-modes. We improve previous estimates…
Can we see a rotating gravitational lens?
Hideki Asada, Masumi Kasai
It is known that the rotation of a gravitational lens affects properties of images. We consider an inverse problem: If the lens is dark, can we infer its rotation from the observed…
A radio-microlensing caustic crossing in B1600+434?
L. V. E. Koopmans, A. G. de Bruyn, J. Wambsganss +1
First, we review the current status of the detection of strong `external' variability in the CLASS gravitational B1600+434, focusing on the 1998 VLA 8.5-GHz and 1998/9 WSRT multi-f…
Deformations of Accreting Neutron Star Crusts and Gravitational Wave Emission
Greg Ushomirsky, Curt Cutler, Lars Bildsten
Motivated by the narrow range of spin frequencies of nearly 20 accreting neutron stars, Bildsten (1998) conjectured that their spin-up had been halted by the emission of gravitatio…
