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…
Spherical harmonics representation of the gravitational phase shift
Slava G. Turyshev, Viktor T. Toth
We investigate the general relativistic phase of an electromagnetic wave as it propagates in the gravitational field of the Earth, which is modeled as an isolated, weakly aspherica…
Science opportunities with solar sailing smallsats
Slava G. Turyshev, Darren Garber, Louis D. Friedman +25
Recently, we witnessed how the synergy of small satellite technology and solar sailing propulsion enables new missions. Together, small satellites with lightweight instruments and…
Imaging faint sources with the extended solar gravitational lens
Slava G. Turyshev, Viktor T. Toth
We consider resolved imaging of faint sources with the solar gravitational lens (SGL) while treating the Sun as an extended gravitating body. We use our new diffraction integral th…
