Phantom-divide crossing and suppressed structure growth in kinetically braided dark energy with momentum exchange
Masroor C. Pookkillath, Shinji Tsujikawa
We construct a linearly stable scalar-field model that realizes both an upward crossing of the dark-energy equation of state, from to , and weakened…
Effective field theory of coupled dark energy and dark matter
Katsuki Aoki, Jose Beltrán Jiménez, Masroor C. Pookkillath +1
We formulate an effective field theory (EFT) of coupled dark energy (DE) and dark matter (DM) interacting through energy and momentum transfers. In the DE sector, we exploit the EF…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
CMB spectrum in unified EFT of dark energy: scalar-tensor and vector-tensor theories
Katsuki Aoki, Mohammad Ali Gorji, Takashi Hiramatsu +3
We study the cosmic microwave background (CMB) radiation in the unified description of the effective field theory (EFT) of dark energy that accommodates both scalar-tensor and vect…
Minimal theory of massive gravity and constraints on the graviton mass
Antonio De Felice, Shinji Mukohyama, Masroor C. Pookkillath
The Minimal theory of Massive Gravity (MTMG) is endowed non-linearly with only two tensor modes in the gravity sector which acquire a non-zero mass. On a homogeneous and isotropic…
Addressing tension by means of VCDM
Antonio De Felice, Shinji Mukohyama, Masroor C. Pookkillath
In this letter we propose a reduction of the tension puzzle by means of a theory of minimally modified gravity which is dubbed VCDM. After confronting the theory with the exp…
