Gravitational lensing in modified Newtonian dynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 AbstractGravitational lensing is most often used as a tool to investigate the distribution of (dark) matter in the universe, but, if the mass distribution is known a priori, it becomes, at least in principle, a powerful probe of gravity itself. Lensing observations are a more powerful tool than dynamical measurements because they allow measurements of ...

Continued Gravitational Collapse for Newtonian Stars [PDF]
Archive for Rational Mechanics and Analysis, 2020 AbstractThe classical model of an isolated selfgravitating gaseous star is given by the Euler–Poisson system with a polytropic pressure law $$P(\rho )=\rho ^\gamma $$ P ( ρ ) =

European Physical Journal C: Particles and Fields, 2018 We construct a general stratified scalar theory of gravitation from a field equation that accounts for the self-interaction of the field and a particle Lagrangian, and calculate its post-Newtonian parameters.

Precision measurement of the Newtonian gravitational constant [PDF]
National Science Review, 2020 Abstract The Newtonian gravitational constant G, which is one of the most important fundamental physical constants in nature, plays a significant role in the fields of theoretical physics, geophysics, astrophysics and astronomy. Although G was the first physical constant to be introduced in the history of science, it is considered to be ...

Probing Yukawian gravitational potential by numerical simulations. I. Changing N-body codes [PDF]
, 2009 In the weak field limit general relativity reduces, as is well known, to the Newtonian gravitation. Alternative theories of gravity, however, do not necessarily reduce to Newtonian gravitation; some of them, for example, reduce to Yukawa-like potentials ...

On the Status of the Geodesic Principle in Newtonian and Relativistic Physics [PDF]
, 2011 A theorem due to Bob Geroch and Pong Soo Jang ["Motion of a Body in General Relativity." Journal of Mathematical Physics 16(1), (1975)] provides a sense in which the geodesic principle has the status of a theorem in General Relativity (GR).

On the reduction of general relativity to Newtonian gravitation
Studies in history and philosophy of modern physics, 2019 Intertheoretic reduction in physics aspires to be both to be explanatory and perfectly general: it endeavors to explain why an older, simpler theory continues to be as successful as it is in terms of a newer, more sophisticated theory, and it aims to ...

Relativistic Newtonian Gravitation That Gives the Correct Prediction of Mercury Precession
Journal of High Energy Physics Gravitation and Cosmology, 2018 In the past, there was an attempt to modify Newton’s gravitational theory, in a simple way, to consider relativistic effects. The approach was “abandoned” mainly because it predicted only half of Mercury’s precession. Here we will revisit this method and
