Probing scalar effective field theories with the soft limits of scattering amplitudes (2017)
Journal Article
Padilla, A., Stefanyszyn, D., & Wilson, T. (2017). Probing scalar effective field theories with the soft limits of scattering amplitudes. Journal of High Energy Physics, 2017(4), https://doi.org/10.1007/JHEP04%282017%29015

We investigate the soft behaviour of scalar effective field theories (EFTs) when there is a number of distinct derivative power counting parameters, ρ1 < ρ2 < . . . < ρQ. We clarify the notion of an enhanced soft limit and use these to extend the sco... Read More about Probing scalar effective field theories with the soft limits of scattering amplitudes.

Gravitational Higgs mechanism in neutron star interiors (2017)
Journal Article
Coates, A., Horbatsch, M. W., & Sotiriou, T. P. (2017). Gravitational Higgs mechanism in neutron star interiors. Physical Review D, 95(8), Article 084003. https://doi.org/10.1103/PhysRevD.95.084003

We suggest that nonminimally coupled scalar fields can lead to modifications of the microphysics in the interiors of relativistic stars. As a concrete example, we consider the generation of a non-zero photon mass in such high-density environments. Th... Read More about Gravitational Higgs mechanism in neutron star interiors.

Discovery of 16 new z ∼ 5.5 quasars: filling in the redshift gap of quasar color selection (2017)
Journal Article
Yang, J., Fan, X., Wu, X.-B., Wang, F., Bian, F., Yang, Q., McGreer, I. D., Yi, W., Jiang, L., Green, R., Yue, M., Wang, S., Li, Z., Ding, J., Dye, S., & Lawrence, A. (2017).

We present initial results from the first systematic survey of luminous z ∼ 5.5 quasars. Quasars at z ∼ 5.5, the post-reionization epoch, are crucial tools to explore the evolution of intergalactic medium, quasar evolution, and the early super-massiv...

Radial acceleration relation from symmetron fifth forces (2017)
Journal Article
Burrage, C., Copeland, E. J., & Millington, P. (2017). Radial acceleration relation from symmetron fifth forces. Physical Review D, D95(6), Article 064050. https://doi.org/10.1103/PhysRevD.95.064050

We show that the radial acceleration relation for rotationally supported galaxies may be explained, in the absence of cold dark matter, by a nonminimally coupled scalar field, whose fifth forces are partially screened on galactic scales by the symmet...
