The Symbiosis of Vainshtein and Chameleon Screening
Sergi Sirera, Tessa Baker, Clare Burrage +2
We present the first study of coexisting Vainshtein and Chameleon screening in cosmic structures. Screening hides fifth forces locally, keeping modified gravity viable. Realistic d…
Rolling Galileons: Evolving Braiding Strength for Viable Dark Energy
James Hallam, Krishna Naidoo, Sergi Sirera +1
Motivated by growing observational indications that dark energy may be dynamical, we introduce Rolling Galileon gravity: a minimal shift-symmetry-breaking extension of the cubic Ga…
Constraints on Horndeski gravity with phantom crossing
Krishna Naidoo, James Hallam, Tessa Baker +1
Gravity models in which the dark energy equation of state crosses , also known as the phantom divide, have received extensive interest due to recent analyses favouring this b…
