Emission-angle and polarization-rotation effects in the lensed CMB
Lensing of the CMB is an important effect, and is usually modelled by remapping the unlensed CMB fields by a lensing deflection. However the lensing deflections also change the photon path so that the emission angle is no ...

Numerical simulations of stellar collapse in scalar-tensor theories of gravity
(Institute of PhysicsClassical and Quantum Gravity, 2016-05-31)We present numerical-relativity simulations of spherically symmetric core collapse and compact-object formation in scalar-tensor theories of gravity. The additional scalar degree of freedom introduces a propagating monopole ...

On the equal-mass limit of precessing black-hole binaries
(Institute of PhysicsClassical and Quantum Gravity, 2017-03-23)We analyze the inspiral dynamics of equal-mass precessing black-hole binaries using multi-timescale techniques. The orbit-averaged post-Newtonian evolutionary equations admit two constants of motion in the equal-mass limit, ...
