Peeking under the clouds: Is exoplanet imaging with the solar gravitational lens feasible?

Viktor T. Toth

Exoplanet imaging using the solar gravitational lens is an enticing prospect. The fundamental physical properties of the lens, including its angular resolution and light amplificat…

Pushing limits: Probing new gravity using a satellite constellation

Viktor T. Toth

Building upon earlier work, we explore the limits of using a configuration of satellites to measure the trace of the gravitational gradient tensor using intersatellite laser rangin…

Metric symmetry by design in general relativity

Viktor T. Toth

The usual derivation of Einstein's field equations from the Einstein--Hilbert action is performed by silently assuming the metric tensor's symmetric character. If this symmetry is…

Imaging with a gravitational lens: the geometric view

Viktor T. Toth

We investigate imaging point sources with a monopole gravitational lens, such as the Solar Gravitational Lens in the geometric optics limit. We compute the light amplification of t…

Scalar-tensor-vector-gravity and NGC-1277

John W. Moffat, Viktor T. Toth

NGC1277 is a compact but massive lenticular galaxy that shows no signs of the presence of dark matter. We find that this galaxy's behavior is consistent not only with Newtonian dyn…

Imaging rotating and orbiting exoplanets with the solar gravitational lens

Viktor T. Toth, Slava G. Turyshev

We utilize the well-established properties of the solar gravitational lens (SGL) to consider realistic observational scenarios. Actual exoplanets, which may be the target of an SGL…
