Beyond CDM: Problems, solutions, and the road ahead
Philip Bull, Yashar Akrami, Julian Adamek +37
Despite its continued observational successes, there is a persistent (and growing) interest in extending cosmology beyond the standard model, CDM. This is motivated by a range o…
Testing Gravity Using Dwarf Stars
Jeremy Sakstein
Generic scalar-tensor theories of gravity predict deviations from Newtonian physics inside astrophysical bodies. In this paper, we point out that low mass stellar objects, red and…
Hydrogen Burning in Low Mass Stars Constrains Alternative Gravity Theories
Jeremy Sakstein
The most general scalar-tensor theories of gravity predict a weakening of the gravitational force inside astrophysical bodies. There is a minimum mass for hydrogen burning in stars…
Disformal Gravity Theories: A Jordan Frame Analysis
Jeremy Sakstein, Sarunas Verner
The Jordan frame action for general disformal theories is presented and studied for the first time, motivated by several unresolved mysteries that arise when working in the Einstei…
Astrophysical Tests of Modified Gravity
Jeremy Sakstein
Chameleon and similar (symmetron and dilation) theories of gravity can exhibit new and interesting features on cosmological scales whilst screening the modifications on small scale…
Astrophysical Probes of the Vainshtein Mechanism: Stars and Galaxies
Kazuya Koyama, Jeremy Sakstein
Ghost-free theories beyond the Horndeski class exhibit a partial breaking of the Vainshtein mechanism inside non-relativistic sources of finite extent. We exploit this breaking to…
