DOI: 10.1016/j.jog.2018.05.008
Abstract: Abstract With the progress in clock technology heading towards a relative clock accuracy of 10−18, geodetic applications become feasible, such as determining gravity potential differences over large distances at the level of 0.1 m2 s−2. In this… read more here.

DOI: 10.1063/5.0044930
Abstract: For a singleton planet $P$ with gravitational potential $V$, we show that for each $\varepsilon > 0$ there exists a planet $P'$ with gravitational potential $V'$, with $(P',V')$ "$\varepsilon$-close" to $(P,V)$ (in an appropriate $C^0$-sense)… read more here.

DOI: 10.1093/mnras/stw3143
Abstract: The paper 'The mass distribution and gravitational potential of the Milky Way' was published in MNRAS, 465, 76. An error when converting densities measured in M⊙ pc-3 into units of GeV cm-3 meant that the… read more here.

DOI: 10.1093/mnrasl/sly222
Abstract: We have recently shown that the baryonic Tully-Fisher (BTF) and Faber-Jackson (BFJ) relations imply that the gravitational "constant" $G$ in the force law vary with acceleration $a$ as $1/a$. Here we derive the converse from… read more here.

DOI: 10.1103/physrevd.99.121303
Abstract: We show that equations of Newtonian hydrodynamics and gravity describing one-dimensional steady gas flow possess nonlinear periodic solutions. In the case of a zero-pressure gas the solution exhibits hydrodynamic similarity and is universal: it is… read more here.

DOI: 10.1109/taes.2017.2671522
Abstract: In conditions with limited power, such as when constrained by the solar-cell efficiency and/or with reduced solar radiation, it is necessary to efficiently manage the flight energy to ensure continuous flight of a solar-powered unmanned… read more here.
