abstract
Scalar-tensor theories (STTs) are a widely studied alternative to General Relativity (GR) in which gravity is endowed with an additional scalar degree of freedom. Although severely constrained by solar system and pulsar timing experiments, there remains a large set of STTs which are consistent with all present day observations. In this paper, we investigate the possibility of probing a yet unconstrained region of the parameter space of STTs based on the fact that stability properties of highly compact neutron stars in these theories may radically differ from those in GR.

Constraints on minimally and conformally coupled ultralight dark matter with the EPTA
The EPTA data rule out ultralight dark matter beyond a few tenths of the local density and place orders-of-magnitude stronger limits on scalar couplings to matter.
